For KDE there's Ksnapshot. Pretty sure there's a similar app for gnome
as well..



Oh yes, there is one, a default part of gnome-desktop-environment package.
But I found it likes taking pictures of itself rather then of an active window.
There has to be a delay set, aprox. 1 sec, then click on the window you want to 
screen capture.

I'm "assuming" you're running Squeeze. Not easy to answer your question
without knowing a little more... :-)

What other php and mysql packages do you have installed?


I run Debian Squeeze. The problem appears to be that modules aren�t'
automatically loaded. I can't get php5-curl to work either.

dpkg --get-selections | grep mysql
libapache2-mod-auth-mysql   install



libdbd-mysql-perl   install

mysql-server-5.1install
mysql-server-core-5.1   install
php5-mysql  install
postfix-mysql   install



mysql-client is the only package I use that you don't have installed.



dpkg --get-selections | grep apache



Nothing significant missing there.

What about /etc/apache2/modes-enabled/php5.conf?

Here's your problem. eth0 has no address. The only IPv4 connectivity you
have is to 127.0.0.1/255.0.0.0 via lo (below). Your computer has no way
to reach 192.168.1.254 so is legitimately returning "Network is
unreachable".

Try the following command:

# ip addr add 192.168.1.1 broadcast 192.168.1.255 dev eth0

then point your web browser to "http://192.168.1.254";. As Camaléon and
others have pointed out, you need to have an address on the same subnet
as your router to be able to talk to it. Often, this is done with DHCP,
but you may not have that set up if you've previously configured the
router.

Is this a virtual machine guest or bare metal host?  Usually offsets
this large are only seen on VM guests that aren't setup properly, and/or
riding atop improperly configured hypervisors.  If this is a guest,
configure the underlying host to sync with an NTP pool, enable the ntpd
listener on the host ntpd, and configure the guest ntpd to query the
underlying host.  Never sync a guest OS ntpd to anything but the
underlying host.  You'll also need to stop ntpd in the guest, run
ntpdate once against your host IP, then start the guest ntpd again.

If this is a bare metal host then you probably have a hardware problem.
 In that case your system board will probably need to be replaced.

Re: eog (Image Viewer) all black on jpg images

[Joao Ferreira Gmail]

I've just realised that this does not happen on all JPG files. Only
some.

There are two common characteristics about the pictures that fail:
a) they are about 2,6MB size
b) they were all taken on the same camera

:P

More incredible is that Nautilus is able to show previews for all of
them...

well... nevermind. I have GIMP :)

Receiving fatal flex scanner error

[Harpreet Singh Anand]

Hi All,

I have been using flex (2.5.4-version) for lexical analysis of some files.

For a set of file I am getting following error:

"fatal flex scanner internal error--end of buffer missed"

I have also check the same with 2.5.35 version. It also flags same error.

Is anyone aware of such bug being fixed in any patch.


I have also attached the small lex file and fileset causing the problem.

flex app.l
g++ lex.yy.c
./a.out file1 file2

Intent of Lex file:
It is a simple lex file having simple patterns. There is just a special 
handling for single line c-style comments "//". Upon matching "//" I am eating 
up all characters till newline or file change using yyinput.

Input file set:
File1: last line contains a comment not containing "\n" character.
File2: Has very big comment

Thanks & Regards,
Harpreet Singh

Kernel messages during startup

[Ralf Jung]

Hi list,

every time I boot my laptop (HP Compaq 615) into Debian testing, some kernel 
messages are printed on the boot console:
[0.470960] pci_root PNP0A03:00: address space collision: host bridge 
window [mem 0x000cc000-0x000c] conflicts with Video ROM [mem

(before upgrading to Linux 3.0, only the 2nd and 3rd of these messages was 
shown)

Sometimes I also get this message:
[1.480097] pci :00:04.0: ASPM: Could not configure common clock

Is there anything to worry about, and/or does this qualify as a bug I (sh|
c)ould report?

Kind regards,
Ralf

can no longer print from acroread

[Steve Kleene]

Within the last week or so, my Wheezy machine has lost its ability to
successfully print a test PDF from acroread 9.4.2 to its USB CUPS printer
(Xerox Phaser 6280DN).  The printout is now just a page with a few PostScript
errors.

I don't think this is a CUPS problem.  lpstat -t shows nothing wrong, and I
get a successful printout from the test PDF with this:

/usr/bin/lpr -P Phaser_6280DN test.pdf

It also prints successfully from the Acrobat I have on a virtualbox XP
machine that uses the same CUPS printer.  And as I said, this same test file
printed fine from Wheezy's acroread until recently.  I tried reinstalling
acroread and associated packages, but that didn't fix the problem.

Here's another clue.  If I print from acroread to a file test.ps, I get a
file that on casual inspection looks like PostScript.  However, it fails to
open in gv, XP Acrobat, or Adobe Illustrator, all of which can open PS files
I make with groff.

The problem seems to involve the PostScript Printer Description.  I have
until now been successful with a file /etc/cups/ppd/Phaser_6280DN.ppd.  This
is a PPD provided by Xerox with some fixes (oopstops) that were needed when I
first brought it up.  If I delete that PPD, printing from acroread succeeds,
but then it doesn't offer any of the printer options I like.

Any ideas?  Thanks.

For those of you having trouble with kernel-package and Linux V3 ...

[Stephen Powell]

For those of you having trouble with kernel-package and Linux Version 3,
I have an unofficial patch that may solve your problems, particularly if
you have CONFIG_LGUEST set in the kernel config file or you are trying
to build a headers package.  The patch is available here:
 
   http://users.wowway.com/~zlinuxman/kernel-package/linuxv3.diff
 
(Sorry, I realize that it is customary to include patches in-line in an
e-mail, but my MUA (Mail User Agent) has the nasty habit of inserting
line-feed characters in long lines, expanding tabs to blanks, etc., which
make it useless for posting in-line patches.)

This is an unofficial patch: it does not come from the upstream author
or the Debian package maintainer.  Use it at your own risk.  To apply,
 
   cd /usr/share/kernel-package
   ... (download the patch to the current directory)

hyproc should be logged out and logged in again for the changes to take
effect.

I think I have found the problem :-) I installed php5-curl on my sid
desktop which worked fine. The problem appears to be that the
/etc/php5/apache2/conf.d directory isn't symlinked in Debian 5 and 6
(after a dist-upgrade):

Anyone knows when this changed? This was not the default
configuration in Debian 5 and I couldn't find any reference in the

If this is a bare metal host then you probably have a hardware  
problem.

In that case your system board will probably need to be replaced.


In many cases, judicious use of "adjtimex" to trim the system clock  
can avoid a system board replacement.

Intel LAN controller problems

[Charles Howard]

Hi, 

I've bought a new machine with Intel DH67CF motherboard and am trying to 
install squeeze. 
This has an Intel® 82579V Gigabit Ethernet Controller. 

Using a netinstall cd I get the message that `No ethernet card was detected. 
...'

Intel offers e1000e-1.4.4.tar.gz for this controller. 

(I know that `e1000e' is actually listed as one of the options which Debian 
offers to load. Selecting
this just cycles back to the `No ethernet card was detected' message.) 

So I got debian-6.0.2.1-i386-CD-1.iso and installed it without the network 
options. 
I set out to follow the instructions in the driver README, but I find that 
debian (from first
cd) won't recognize files in a usb stick or a burnt cd. Both dirs show up in 
/media but the actual 
file e1000e-1.4.4.tar.gz doesn't. (Or any other file.) 

I can see a couple of sledgehammer `solutions': 1. buy an additional card which 
works, 2. install the
full squeeze from the eight dvds. But I'd like to sort this out simply if 
possible. 

Can someone please point me in the right direction please? 

C

The problem occurred again. A workaround to avoid the freeze of
the hibernate process was to disable the radio with the hardware
switch.

And if the machine is under depot warranty?  Better yet,  that + on-site
service contract?  If it does turn out to be defective hardware, and the
above is true, I'd have it replaced.

Berfore inserting nomodify the clock lost 2 minutes in 1 hour, now is

I think this isn't a good idea in my case i can't access the server

I have a hp DL360 with same kernel, same squeeze 64bit etc. and there
aren't any issues with ntp how you can see

Hello Stan,

Thanks for your remarks. The disk info is given below. Writing to the
disk is oke when mounted, so I think it is not a hardware/alignment
issue.  However your remarks made me do some additional investigations:

1. dd of=/dev/sdb4 if=/dev/zero gives similar results, so it has nothing
to do with LVM;
2. My statement about writing like this on an openSUSE kernel is wrong.
Also with openSUSE and the same hardware I get similar (slow) results
when writing to the disk using dd via the device file.

So now the issue has diverted to the asymmetric behaviour when
writing/reading using dd directly through the (block) device file.

Reading with dd if=/dev/sdb4 of=/dev/null gives disk limited performance
Writing with dd of=/dev/sdb4 if=/dev/zero gives about a factor 10 less
performance.

However, after mounting a file system on sdb4 (read only), I can use dd
of=/dev/sdb4 if=/dev/zero at (near) disk limited performance.

Now I used this trick to copy a large (raw) disk image onto an LVM
partition. I think this is odd. Can somebody explain why this is like it is?

Here is the disk info:
Model Family: Seagate Barracuda ES
Device Model: ST3750640NS

root@dom0-2:~# fdisk -l /dev/sdb

Disk /dev/sdb: 750.2 GB, 7501

Yep, you also need to run "ifup eth1".

Yep, IIRC it has been replaced (the same as gnomebaker) by Brasero, which

Device seems to be there (usblp1). How about "ls -l /dev/usblp1"?

And this looks like an informative message, I mean, like if it were telling 
you "hey, I have detected an USB device but is not suitable to setting it 
as an MTP". 

Have you tried to set the printer from CUPS web interface?

You can add another printer (I mean, another stanza for the same printer, 
your "Phaser 6280DN") from CUPS that uses the desired PPD (instead PS, 
try with PCL5/6 or another generic file) just to use it to print jobs 
from Acrobat Reader. 

Not a solution at all, I know, but Acrobat Reader is closed source and no 
devel is be able to look into the code so you can only wait until Adobe 
fixes it... (take a chair and wait :-P)

There is an upstream bug for those errors:

I've had this problem for a while and I haven't been able to fix it. Both
kwrite and kedit do not let me insert newlines in the files by hitting
enter. Does anyone have a solution to this problem?

That's the rate of change you see right now, but it may or may not
remain constant.  I'd give it a few days before stamping it as "stable"
or "problem solved".

Well, "nomodify" prevents local *programs* from reconfiguring your ntpd,
such as ntpq, ntpdc, ntpdate, etc.  But this doesn't tend to explain the
drift correction of 2 minutes every hour simply by enabling 'nomodify'.
 That would mean, basically, that some local program is modifying ntpd
every hour by 2 seconds.

Speaking of other tools, what does "ntpdate -q xntp1.inrim.it" return?
It'll tell you how far off you are in seconds.  I can't remember if
offset and jitter reported by nptq are in seconds or milliseconds.

No, probably not, given your circumstances.  You do need to know if this

[maybe OT] unicode control characters in filenames

[Eike Lantzsch]

Hi:

For some time I'm looking to find a method to remove unicode control 
characters like U+202A; U+202C; U+200F from filenames.
I found lots of examples to do this programmatically with python, perl, even 
for VB and Java.
I was looking to do this with bash, find, grep and/or even sed because I just 
never wrote code in python or perl.
Can some kind soul please give me a hint how to proceed?

Oh well, Dolphin in KDE 4.7.0 lets me change the filenames manually without 
showing the actual control characters - you sort-of need to "feel" your way - 
which is OK. Dolphin interprets those characters as what they are: control 
characters - but manually file by file - I got hundreds - good grief!
ls -la is so kind as to show the unicode characters as  and so forth.
Even mc shows at least dots for the unicode charcters, but no easy method or 
function to eliminate those chars from filenames - I mean a method simple 
enough and usable for simple-minded-non-perl-cracks-users like me.

Thank y'all
Eike

I'm not sure what PPD I'd use.  With the XP virtual machine, I fixed a
similar problem by switching (at your suggestion) to the PCL description.
However, Xerox doesn't offer a Linux PCL file for this Phaser.

What's more baffling to me is why printing from acroread just stopped
working.  Neither the PPD nor any of the acroread packages have changed since
I built Wheezy five months ago.  I noted on June 24th that printing from
acroread worked, and I think it only stopped working a week or two ago.

Thanks.

It also blinks (appears/disappears) sometimes/randomly for me (wheezy)... 
maybe this is something related with the VGA driver in use, in my case, 
intel.

I'm not aware of such parameter during install :-?

There are some options you can tweak to control the behaviour of the 
jumping/bouncing icon when clicking over icons to run applications but I 
don't think this is going to have any effect over the "blinking" issue...

Problem with USB storage device - video glasses

[Bret Busby]

Hello.

I have a pair of video glasses, that apparently, include 8GB of storage.

The problem is that, whilst, when connected to the computer USB, the 
battery charges okay, and, when recording video, the correct messages 
are played at the start and end of recording, the computer running 
Debian 5.0, does not show the USB storage device as being present.


The storage device should have about an hour of video, stored on it, 
which should be about 2GB, stored as an AVI file.


I have used the computer with the USB for downloading images from 
different digital cameras without any problem, and for writing to and 
reading from, USB thumb drives, and, accessing an external USB hard 
drive, all without problems.


But, the computer appears unable to detect the USB storage device in 
this device.


dmesg | tail -20 results in

"

But, no reference to the device, is displayed in either the file 
manager, or, on the desktop, and, when I connect a digital camera, I get 
something like A storage device has been found. Do you want to import 
images".


What is wrong, and, why can I not access the device?

Thank you in anticipation.

Mmmm, you're right:

http://www.openprinting.org/printer/Xerox/Xerox-Phaser_6280

There is only one driver (PS) for linux though the printer supports 
PCL6 ;-(

(trick: you can try with a generic PCL6 driver¹)

There have been some updates for CUPS, IIRC. Anyway, just for printing 
can't you use another PDF reader, like Evince or Okular :-?

that depends on which messages you mean: The messages coming from the kernel 
(recognisable by the [timestamp]) end up in /var/log/dmesg, the easiest way to 
read them is the "dmesg" command. However, there are many more messages there 
that are not printed, you can to look for the ones you grasp during startup.
For messages from the init scripts, you have to enable boot logging 
(http://www.go2linux.org/bootlogd-to-read-boot-console-messages), then you can 
find them in /var/log/boot.

Kind regards,
Ralf

Run:
/$ dd of=/dev/sdb4 if=/dev/zero bs=4096 count=50

Then run again with bs=512 count=200

That will write 2GB in 4KB blocks and will prevent dd from trying to
buffer everything before writing it.  You don't break out of this--it
finishes on it's own due to 'count'.  The second run with use a block
size of 512B, which is the native sector size of the Seagate disk.
Either of these should improve your actual dd performance dramatically.

When you don't specify a block size with dd, dd attempts to "buffer" the
entire input stream, or huge portions of it, into memory before writing
it out.  If you look at RAM, swap usage, and disk IO while running your
'raw' dd test, you'll likely see both memory, and IO to the swap device,
are saturated, with little actual data being written to the target disk
partition.

I attempted to nudge you into finding this information on your own, but
you apparently did not.  I explained all of this not long ago, either
here or on the linux-raid list.  It should be in Google somewhere.
Never use dd without specifying the proper block size of the target
device--never.  For a Linux filesystem this will be 4096 and for a raw
hard disk device it will be 512, optimally anyway.  Other values may
give better performance, depending on the system, the disk controller,
and device driver, etc.

That Seagate isn't an AF model so sector alignment isn't the issue here,
just improper use of dd.

Yes, I use auto eth0 eth1
I am glad for your improving my scripts, I like it.
I will use one or the other you suggested here.
Many thanks.

Console User Groups Best Practice?

[Bob Proulx]

How are people handling the setting of user groups for 'audio' et al
needed for the console user in a network account environment such as
NIS/YP?  Where any user can log into any workstation?

For a Debian default standalone installation the user is normally
added to the set of console groups in /etc/group.  I understand how
that part works in great detail.  The user logs into the console and
is a member of the needed groups for audio and others on the console.
But for networked account management with a large number of users
adding every user to every console group has its own set of problems.

On Red Hat / Fedora systems and I presume others they use the PAM
module pam_console.so to set the ownership of files matching the lists
in the /etc/security/console.perms file.  This has obvious exploits.
The Debian maintainer has decided not to include it in Debian and I
think that is reasonable.
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=69550

What is the best practice for handling this type of network account
management in Debian?

Thanks,
Bob

Thing is, this happens with Squeeze onwards, not in Lenny backwards.
I also notice a bit of sluggish desktop performance in Squeeze compared
to Lenny. I associated the cursor behavior with it. 

I have dual boot of both, same set of apps, so I can evaluate a little
bit.

Sometimes cursor disappears for good of a second, I have to double click
icons once, twice, sometimes even thrice, before a folder opens up,
mounted cdrom opens, etc.

Not sure, so far Lenny outperforms Squeeze at least on my hardware.

What's the result of the following command?

Is it possible to mount /dev/sdb manually?  E. g.:

$ sudo mount -v /dev/sdb /mnt/

What are the messages displayed by the command above?



sudo doesn't work on this one (Yay!)

using su - root (which is my preference) gives

"

Mounting manually, using that, worked.

Thanks for that.

I do not understand why it was not automatically mounted, like the other 
USB devices that I mentioned in the previous message.

network devices have vanished on Dell D600

[Mark Grieveson]

Hello. I have a Dell Latitude D600. I successfully installed Debian
and the firmware for the two network devices on the laptop, those being
a Broadcom NetXtreme ethernet card (using firmware tg3) and an Intel
PRO/Wireless Network Connection (using firmware ipw2100). This was
working fine. However, this morning I find that the laptop is not
seeing either of these devices. From the syslog, I find: 

[6.512468] ipw2100: eth0: ipw2100_verify failed: -5 
[6.512850] ipw2100: eth0: Failed to power on the adapter. 
[6.512880] ipw2100: eth0: Failed to start the firmware.

I'm attaching further syslog entries on eth0 and eth1 in a text file.
From this file you can see that the device were working, and now they
mysteriously are not. Here is what iwconfig now looks like: 

root@debian:/home/mark# iwconfig
lo no wireless extensions.

pan0   no wireless extensions.

Before iwconfig had eth0 and/or eth1 listed, with one having a bunch of
stuff beside it.  At this point wireless was working.

Anyone know why this is happening? Is it normal for these network
devices to sometimes not be found? If it's not normal, can I fix it?

Mark

Boost sound volume?

[Robert Blair Mason Jr.]

Hi list,

Is there a way to boost the system sound volume?  Playing DVDs in VLC
with the alsa, pulseaudio, and vlc volumes all maxed out is still about
30-40% of max volume in 'doze.  I don't like pulseaudio, but for some
reason skype doesn't work without it, and my family won't allow me to
not have working skype, so for now I'm stuck with it...

Thanks!

Visited URL links in Epiphany

Hello List,

How do I enable the functionality, that already visited URL links in
Epiphany web browser, are shown in a changed colour? 

I was looking for some type of extension because I have installed just
bare Epiphany package. And visited links do not change the colour so far
for me.

Will any of these do the trick?
$ apt-cache pkgnames epiphany
epiphany-browser
epiphany
epiphany-webkit

Thanks Stan. The motherboard has onboard video. But the behaviour of the
machine is the same with or without the PCIe video card.

And the machine does not boot anymore with any of the RAM modules.
Assuming that all the memory modules were not zapped together, it is
quite likely the CPU is toast. I can only check this using another
machine like this. I might be able to do that tomorrow (and some
memtest86 too).

all running ssh-sessions to that machine freeze the moment it tries to

I had some tail -f's running in ssh-sessions on

Unable to create either bootable USB flashdrive or CD/DVDrom

[Christian Jaeger]

Hello

This is not the first time I'm struggling trying to make a bootable
USB flashdrive. In fact, I've spent like 5-10 hours across various
times already, and I realize that I've been too stupid to document my
last endeavours enough to help me to get it to work this time (or
maybe I did and just something has changed with recent images?).

This is the first time though that I find myself even unable to create
a bootable CD or DVDrom. I've burned these and none of them boot on my
ThinkPad T61:

- MythBuntu to a DVD-R
- XMBC live CD to a DVD-R
- MythBunto to a CD-R
- Squeeze netinst to a DVD-R

The first three fail with either just the screen going black and
rebooting in an endless cycle or, in the case of XMBC (with 'quiet'
option removed in the boot menu) showing "Kernel panic - not synching:
VFS: Unable to mount root fs on unknown-block(1,0)". I then tried the
debian-6.0.2.1-ia64-netinst.iso image on a DVD-R, ("wodim
debian-6.0.2.1-ia64-netinst.iso"), in this case wodim told me "wodim:

contents without a single error, so I'd say the disc is fine? But when
booting from it, the screen shows two random characters (otherwise
empty) and then it's frozen (except for the cursor in the top left
corner still blinking, but that's maybe handled by the HW or the
bios).

The laptop *does* boot from a XubunTOS-1.0 CDrom I burned years ago, though.

So I tried the next step (using unetbootin 549-1, recompiled from
testing on squeeze some time ago--I did this because the version in
Squeeze wouldn't work for me back then, the recompiled version did):

- MythBuntu to USB stick using unetbootin: shows "Kernel panic - not
synching: VFS: Unable to mount root fs on unknown-block(104,0)"
- MythBuntu to a second USB stick unetbootin, same
- Squeeze netinst using cat $image.iso > /dev/sdb  (device of stick):
doesn't even show boot menu
- Squeeze netinst using unetbootin: iirc not even the boot menu showed up

Then I tried compiling "usb-creator" from ubuntu, from
https://launchpad.net/ubuntu/oneiric/+source/usb-creator/0.2.31, on
Squeeze,

- at first using dpkg-buildpackage, but there are dependencies on a
newer python-gobject and on gir1.2-gtk-3.0 and other libs, so I gave
up,
- using "make", then running bin/usb-creator-gtk, gave same message as below,
- using "python setup.py install" then:

Since I don't know what that issue is, I've given up.

Could you help me in any of these attempts? Of course I don't expect
you to help me debug problems with Mythbuntu or XMBC, but as you see
there are already multiple Debian-only problems I'm dealing with.

Re: Unable to create either bootable USB flashdrive or CD/DVDrom

[Dejan Ribič]

Dne 9.8.2011 22:14, piše Christian Jaeger:

Hello

This is not the first time I'm struggling trying to make a bootable
USB flashdrive. In fact, I've spent like 5-10 hours across various
times already, and I realize that I've been too stupid to document my
last endeavours enough to help me to get it to work this time (or
maybe I did and just something has changed with recent images?).

This is the first time though that I find myself even unable to create
a bootable CD or DVDrom. I've burned these and none of them boot on my
ThinkPad T61:

- MythBuntu to a DVD-R
- XMBC live CD to a DVD-R
- MythBunto to a CD-R
- Squeeze netinst to a DVD-R

The first three fail with either just the screen going black and
rebooting in an endless cycle or, in the case of XMBC (with 'quiet'
option removed in the boot menu) showing "Kernel panic - not synching:

Hi,

are you sure you should be using IA64 netinst ISO? what kind of CPU do 
you have?

Most command line utilities predate unicode and only understand bytes.
While I don't know unicode I have had to deal with such in files and 
have used some thing similar to  tr "\200-\377" "_"  or
if you need to more definition use sed's 's/\107\221\168\319/_a_/'.
You can put all the translations in a sed file one character sequence
translation per line, then something along the lines of:

readable_filename = $( echo $unicode_filename | 
sed -f translation_file.sed; ); 
mv $unicode_filename $readable_filename ;


Mind you the former may give you duplicate file names which will result
in one of the files disappearing and the latter requires you to figure
out some mapping between the old and new file names that will be 
recognizable by anyone else involved.
Since using a script to diddle 100s of files is fraught with risk
I strongly suggest you zip up the directories in question and save that
zip for a month or 2 until you are SURE there are no mistakes.

To get a list of the unicode groupings you need to deal with
start with:
 ls -1R /path_to_unicode_files | tr 'a-zA-Z0-9./-' '_' 

I've never had to deal with your problem but that's how I'd approach it.

HTH,
Mike
PS: \107\221\168\319 is totally arbitrary and only meant to be
illustrative and you may find \x0A handier.

I don't know where you are located, but consider carefullyyou may have 
toasted the A) RAM B) CPU C) mltherboard D) all of the above E) something else 
that is bringing the entire system down.  By putting potentially broken 
components into a good system, you can also toast components on the good 
system. This will cost you more than taking the system into a reputable repair 
shop and having them diagnose the problem(s) for you.  I recently did that and 
I considered the $70 diagnostic fee to be cheap because then I knew exactly 
what to replace.

For future reference, you are best off if when doing something with RAM, you 
get a complete matched set of memory.  Don't mix and match.

You may want to consider putting the sed script in a file and using the

Re: Unable to create either bootable USB flashdrive or CD/DVDrom

[Christian Jaeger]

So, I've downloaded
http://cdimage.debian.org/debian-cd/6.0.2.1/amd64/iso-cd/debian-6.0.2.1-amd64-netinst.iso,
run "gparted /dev/sdb" to make a new partition table on my flashdrive
and one fat32 fs partition, run unetbootin and selected the downloaded
iso file and the flashdrive as target, try to boot from it, the menu
comes up, then a plain old "Kernel panic - not syncing: VFS: Unable to
mount root fs on unknown-block(254,32)".

So, back to "wodim -v debian-6.0.2.1-amd64-netinst.iso" on a DVD-R,
which prints the same error message about fixating (see attached files
for the wodim and kernel output if interested), but the resulting CD
actually *does* boot! The installer comes up and runs just fine.

So where does that leave me? What does it show?

1. unetbootin is still broken (unable to make *any* image work on flashdrive)
2. all Ubuntu based images I tried are broken regardless of whether on
flashdrive or DVD or CD. But these images must be working for the
majority, so why not for me?

Christian.

Yes, unetbootin is and has been broken. Why don't you follow the method

Have you used a flashlight to check under the motherboard and other
places for dust, lint, loose screws, etc? Lots of things you won't see
without a flashlight.

Have you taken a vacuum cleaner to the slots and, well, everything?
(Carefully, of course.) Even just a year can be enough to build up
quite a bit of lint and dust, and those tend to "break" electronics as
quickly as anything. Vacuuming can often be a quick cure for a lot of
things.

Just make sure you're careful about static electricity, and avoid
knocking off parts, vacuuming up delicate parts, or bumping things and
"mis-adjusting" them, especially very low reactance coils (single, or
even half-loop coils, and single-plate air capacitors) which you may
not recognize as such at first.

Have you used an eraser to clean the fingers of your memory boards?
The original ones, especially.

Again, be somewhat careful to avoid letting the eraser knock parts off
the board and such. And make sure you hold the board so that the
eraser dust doesn't fall into or under parts.

I guess that it may be because the block device in question
lacks a partition table, and the automounting facility used
assumes that it should have one.

It may be possible to add a partition table to the device
(obviously destroying the contents), but it should be checked
whether the device itself supports writing to a filesystem on a
partition.

The double quote character within Shell's double quotes can be
escaped with a backslash (“\”):

   sed -i "s|^\( *PATH=\"\)\(.*\)|\1${ADD}:\2|" 

However, one is by no means forced to use just one kind of
quotes in Shell, so the following is also possible:

   sed -i 's|^\( *PATH="\)\(.*\)|\1'"${ADD}"':\2|'
