You can mount iso disk images. Try making the file with a .iso extension.

mkdir ~/CDROM

mount <./file.iso> ~/CDROM

umount ~/CDROM

Claws mail directly supports IMAP, POP3, SMTP and NNTP without an MTA
or fetchmail installed.

You also don't need sendmail nor the sendmail command to send mail via
SMTP with Claws Mail.

Head over to https://lists.claws-mail.org/cgi-bin/mailman/listinfo/users

Maybe even subscribe to their list.  Expect to have to give people some
useful information, like what error messages you receive and what version
of CM you're using.  The latter makes a difference, *especially* with
google because older versions won't do Oauth2.

Expect to have to do some work in CM and at google's site to enable
successful mail transfers to take place.  Other providers should be
easier to set up.

The way out of this is having strong local user groups, which is,
of course, easier in densely populated areas.

In Berlin, e.g., there were several linux user groups which had
"open days" (some even once a week) where people went with their
hardware and got it fixed. And got to know nice people. Often
at no cost.

In the smaller city I live now there is at least one such place.

Support your local free software support group :-)

Hi Mike,

What you see as a command prompt in MC is controlled by the value of the
parameter PS1 in the environment that is externally provided to MC when it is
executed.

How to specify that value of PS1 is given will depend on from where you
start MC.
- perhaps in a virtual linux console
- perhaps in a terminal emulator program running under a GUI desktop

You can see and change the value of PS1 by doing this in MC:
- press control-O to have MC start a shell
- enter the command 'echo $PS1' (without the quotes)
- you can change the value of PS1 using a command like 'PS1=foo' (without
  the quotes)
- you can play with it because any changes you make will only affect the
  current instance of MC
- press control-O to toggle between the shell and MC

The content of PS1 is documented in 'man bash', search for PS1 and/or
PROMPTING.

That's all I have time to write. I have nothing to say about the delay,
that's a different issue.

If you want to ask how to set the value of PS1 before MC starts, you will
need to tell us exactly from where you start MC, as I mentioned above.

"... There is one problem with this approach, as stated earlier. For the

makes such an email detached from the main thread and treats it as a
different subject. Had Mailman also had(sic) an email editor for
posting messages, that would have been a better option.

"However, I understand the difficulties and the legalities associated

that with your greater experience, expertise and wisdom, you would be
able to guide me in this regard, w.r.t. gmail and Mailman."

I assume that MHonArc is only about conversion of our emails into

Please correct me if I am incorrect.

As said, please advise and guide me on this issue.

What kernel, systemd and udev versions are installed and running in
the Bookworm install?

Just how _did_ you "upgrade" the system while retaining the ability to
boot the older install? I take it that this would mean that you didn't
do the normal in-place upgrade but rather something else, and exactly
what that something else is might provide clues. Alternatively, please
specify more exactly what you mean by "boot bullseye" and "boot
bookworm".

Do you see any difference if you hook up a USB 2 device to a port
which is physically USB 2 or USB 3?

Indeed, technically-inclined people are often better served with Free
Software, and Free Software can also be a great choice for large
corporations who can either have on-site techsupport people or can hire

USB2 not working after upgrading to bookworm

[Rafa]

Hi,

I have an issue regarding USB2 after upgrading a desktop machine from
Debian 11 (bullseye) to Debian 12 (bookworm).

USB3 ports work fine, but USB2 ports do not.

I still have bullseye installed in the machine and when I boot bullseye
I can use both USB2 and USB3. But when I boot bookworm I can only use
USB3.

I have compared the output from the "lspci" and "lsusb" commands
obtained with bullseye and with bookworm, but they seem quite similar to
me.

In bookworm, command "dmesg -w" writes out several error messages like
the following when I plug a USB device in a USB2 port:

  usb 4-1: device descriptor read/64, error -32

  usb 4-1: device not accepting address 4, error -32

The landscape of ISO files is wide and varied.
An URL for getting the ISO would help to make more specific statements.

The UUID as of program lsblk is a property of the data which is stored
on the device, not of the device itself.
For example after dd'ing debian-12.0.0-amd64-netinst.iso :

  $ lsblk -o NAME,UUID /dev/sdc
  NAME   UUID
  sdc2023-06-10-10-25-55-00
  ├─sdc1 2023-06-10-10-25-55-00
  └─sdc2 DEB0-0001

Because there is no valid GUID Partition Table in this ISO, the UUIDs are
fabricated and don't deserve the attribute "Universially Unique".
sdc and sdc1 get the creation date of the ISO 9660 filesystem as Id.
sdc2 gets the Volume Serial Number of the FAT filesystem (just 4 bytes)
as UUID.

It does not look better with PARTUUID instead of UUID:

  $ lsblk -o NAME,PARTUUID /dev/sdc1
  NAME   PARTUUID
  sdc1 23261683-01

The shown id "23261683" is the hex representation of the MBR Disc
Signature which has 4 bytes.


> I want to dd it automatically like
> dd if=/path/to/my/image.iso of=UUID=34567890-afde-.-1234

Consider refering to hardware properties, e.g. by using the symbolic links
in /dev/disk/by-id .

  dd if=/path/to/my/image.iso \
 of=/dev/disk/by-id/usb-INTENSO_USB_AA0401287699-0:0

Device link name found by knowing that this time the USB stick is sdc:

  $ ls -l /dev/disk/by-id
  ...
  lrwxrwxrwx 1 root root  9 Nov 12 19:14 usb-INTENSO_USB_AA0401287699-0:0 
-> ../../sdc
  ...

I am still intrigued by the idea of an iso file having a UUID when
it's written directly to a USB disk though. I didn't think that
happened. I don't have a USB stick to hand right now and my searches
as to whether ISO images have UUIDs have not proven conclusive as of
yet.

I must admit it's been ages since I looked into the details of iso
images so perhaps I was mistaken in saying they would not have a
UUID. If they can/do have a UUID then perhaps they can also have a
label, which may help if the device id method doesn't suit you.

Ultimately though, you are probably constrained by the info that
appears in /dev/disk/by-* as that is what Linux tools will be using
for mounting. So that's the place to look to see what your options
are.

Thanks,
Andy

I would agree with that, though there is one thing you should check
first, and that is that you're not using one of a set of identical
USB sticks that have the same ID (or, if you are, that you have some
physical means of distinguishing between them).

Re: UUID permanent at removable device?

[Hans]

Hi Andy,

to make things more clear. This is what I want to do:

I am using bootcdwrite, which writes its cdimage.iso to a mounted (because of 
to few disk space) to a mounted external harddrive. 

This one got a UUID, which never changes, so I can mount it automatically. All 
this is working perfectly.

After the image is created, I want automatically install this image to an USB-
stick using dd. Manually this is working well with this shell script, if in 
this shell script the device is correctly defined. 

The line is just:

dd if=/var/spool/bootcd/cdimage.iso of=/dev/sdc

Nothing special! But if I maybe put in two USB-sticks then the wrong one might 
be /dev/sdc and the script would overwrite the wrong device.

Thus my idea, just use UUID for identification, define the correct UUID in the 
script and the script will always write to the correct USB-stick, regardless, 
how many or in which order I put them in.

As any overwrites changes the UUID of the partition of the partitions, I was 
asking myself, if it would overwrite the device UUID. 

blkid /dev/sdb1 or /dev/sdb is showing me a PTUUID, a PARTUUID and a UUID, 
whic is the same for /dev/sdb and /dev/sdb1, and I am asking myself, if I 
could use this in my script or if these would change everytime I am using dd.

I dunno if my thoughts are working at all, if this, what I intend to do, is 
not possible at all, then I will find another solution. Or doing just manually 
as before.

Hope, this helps.

Best regards

Hans

I agree with you when it comes to systems that are used purely for
backups in a style that mimics tape backup, i.e. rare need for
random access, which from what I understand does cover Gene's
situation as Gene is used to using Amanda for backups, which is a
(virtual) tape paradigm.

However, especially in a home setting, people often ask more of "the
server", turning it into something that isn't entirely, or even
primarily, a backup server. If those uses involve random access, SSD
of some kind will be very beneficial.

Also there are quite a few backup technologies that do use random
access a lot. A venerable one often mentioned on this list is
rsnapshot or its basic implementation using rsync. This walks the
entire backup tree at every iteration checking metadata and creating
hardlinks. The period of time spent deciding what to back up and how
often massively exceeds the time spent transferring and writing the
data with these systems. They will also massively benefit from low
latency storage on SSD.

So just as a word of caution -- and I know you know this, David -- I
want to say check how much random access is going on, before
deciding rotational media will cut it.



I think we agree that HDD's are slower for many (most?) backup/ restore 
use-cases.  But, I think the slowness is acceptable for the off-hours, 
once a day backup use-case and for the infrequent file restore use-case 
that I anticipate Gene will perform.




PS I stated this before and I have to say it again though: while
building a dedicated backup system seems like a great idea for
Gene's use case, the practical situation for Gene is that he's
been trying for literal years now to make a very simple RAID10
mdadm work on perfectly serviceable hardware. This should be a
simple task, but it's not gone well for him and this list is
unable to get to the bottom of why (I include myself in that, but
I think it reflects more on communications difficulties than a
shortcoming of Linux mdadm). 



There appears to be consensus to set up one storage device with one 
partition and one ext4 file system, and test the various applications 
for file access issues.  It is up to Gene to decide if, what, where, 
when, and how.




I am at a loss as to why, given
those facts, people are still advising Gene to build an entire
new system out of parts. It makes sense for the use case but not
for the user. I don't think it's supportable. For this user I
would have to still stand by my advice of buying an off-the-shelf
NAS.



I think we agree that everyone needs backups.


It is my impression that most of Gene's eggs are in one basket (the 
computer with the Asus Prime Z370 A II motherboard) and that Amanda has 
been broken for a while (?).  I would celebrate Gene implementing 
working backups by any means on any device and any media.  Again, Gene 
decides.

If your use case is writing an ISO file directly to a USB device (no
partitioning) then I'd think you could use the ID of the USB stick
to mount it in future. You can find these in /dev/disk/by-id and it
will remain the same for the life of that stick.

Re: UUID permanent at removable device?

[Andy Smith]

Hello,

TL;DR: Use filesystem labels. This is the sort of thing they're for.

Do you literally mean a GPT PARTUUID? Or do you mean a filesystem
UUID?

GPT partitions can also have a user-specified name. This is rarely
used.

MBR labels have a disk identifier which is incremented for each
partition, so disk with MBR partitions can also have PARTUUIDs. This
is really rarely used.

> But does the UUID also change of the device itself? Does the UUID of /dev/sdc 
> change, too?

Devices don't have a UUID (except that disk identifier for MBR as
mentioned). GPT partitions do have a PARTUUID. And the filesystem on
them does also have a UUID. So sdc being a disk not a partitions,
won't have a PARTUUID but could have a filesystem UUID if you put a
filesystem on it.

UUIDs are meant to be unique, thus on filesystem creation they will
be random, and anything that copies the filesystem will copy around
the UUID as well because it's a property of the filesystem.

For your use case you will be wanting to use the relevant
filesystem-specific tool to write an fs label that you choose. Often
this can be done at mkfs time, but there should also be a tool to
query/change thre fs label afterwards as well. For ext* filesystems,
that tool is "e2label".

You can mount by label and also add an fstab entry by label.

Here is a fairly exhaustive discussion of your options:

https://wiki.archlinux.org/title/fstab

If you meant GPT PARTUUIDs and absolutely insist on setting a
PARTUUID to a known value instead of just accepting the random one
that is picked at the time the GPT label is created, you can do it.
e.g. with gdisk:

UUID permanent at removable device?

[Hans]

Hi folks, 

just a question. 

I want to automatically create a bootable USB-stick using dd from an ISO-file.

As I want to always the same USB-stick, I would like to mount it using a shell 
script.

However, after generating the stick the UUID of the first partition (/dev/sdc1) 
is changing, so next time, the script will not work again, of course.

But does the UUID also change of the device itself? Does the UUID of /dev/sdc 
change, too?

I would like to work with UUID, as I never know, if the USB-stick I put in is 
/dev/sdb or /dev/sdc. Thus UUID would be my favourite solution, but this would 
of course only work, if the device UUID after dd will not change.

Happy for any answers.

As always, it depends on what you already have. Much of that enormous
list may already be there.

From a fairly large sid installation:

Install: libtspi1:amd64 (0.3.15-0.3, automatic), libzxcvbn0:amd64
(2.5+dfsg-1, automatic), keepassxc:amd64 (2.7.4+dfsg.1-2),
libbotan-2-19:amd64 (2.19.3+dfsg-1, automatic)

An alternative strategy is to keep the database backed up on a USB
device or uSD card etc. I do that anyway for laptop use, not
storing the database on the laptop itself. You could also install
PortableApps (and KeepassXC Portable) on the card, and have the
passwords available on any Windows machine without leaving anything
behind on that machine. Whatever you do, it's always a good idea to
copy the database to somewhere fairly safe whenever you update it.

Or there are other rescue-type distributions which have keepasxc, such
as Parted Magic. Knoppix has keepassx, but I'm not sure about file
compatibility with that fork.

This at least partly because the USB devices on, say, a Raspberry Pi

This is what I meant: this is why the devices from QNAP / Synology that

When you install a .deb package it only installs to the

If the package to install has been made available to you under the form
of a simple .deb file without any associated package repository, it is
still possible to use APT to install it together with its dependencies
(provided that the dependencies are available in the configured
repositories) with a simple command: apt install
./path-to-the-package.deb. The leading ./ is important to make it clear
that we are referring to a filename and not to the name of a package
available in one of the repositories.

OK.  If I'm not mistaken, that file never contained a PATH definition
in the first place, so you can put things back to normal simply by
deleting the line(s) that you added to that file.

If you want to fix su, my personal recommendation (out of all the options
that are on the NewInBuster wiki page) is this one:

unicorn:~$ cat /etc/default/su
ALWAYS_SET_PATH yes

Just create that file, and put that line in it.  It's what Debian should
have done for you.

When you install a .deb package it only installs to the
fully-qualified paths inside the .deb file. It doesn't install
anything to the current directory, so it doesn't matter where the
.deb is located when you issue "dpkg -i" or "apt install ./file.deb"

(I am not sure if it is even possible for a .deb file to contain a
relative file path, but if it is, they typically don't.)

That doesn't install the dependencies.  It may leave your packages in
a semi-broken state, requiring you to run "apt-get -f install" afterward
to fix it.

Using "apt install ./debfile.deb" pulls in the dependencies and keeps
things in a working state at all times, if possible.

Using "dpkg -i" and then "apt-get -f install" was the old way.  You'll
still see people recommending it, because they don't know any better,
and old methods that still "work" (most of the time) take a long time
to die out.

It doesn't help that "apt install ./file" is not documented in the

I agree with you when it comes to systems that are used purely for
backups in a style that mimics tape backup, i.e. rare need for
random access, which from what I understand does cover Gene's
situation as Gene is used to using Amanda for backups, which is a
(virtual) tape paradigm.

However, especially in a home setting, people often ask more of "the
server", turning it into something that isn't entirely, or even
primarily, a backup server. If those uses involve random access, SSD
of some kind will be very beneficial.

Also there are quite a few backup technologies that do use random
access a lot. A venerable one often mentioned on this list is
rsnapshot or its basic implementation using rsync. This walks the
entire backup tree at every iteration checking metadata and creating
hardlinks. The period of time spent deciding what to back up and how
often massively exceeds the time spent transferring and writing the
data with these systems. They will also massively benefit from low
latency storage on SSD.

So just as a word of caution -- and I know you know this, David -- I
want to say check how much random access is going on, before
deciding rotational media will cut it.

Thanks,
Andy

PS I stated this before and I have to say it again though: while
   building a dedicated backup system seems like a great idea for
   Gene's use case, the practical situation for Gene is that he's
   been trying for literal years now to make a very simple RAID10
   mdadm work on perfectly serviceable hardware. This should be a
   simple task, but it's not gone well for him and this list is
   unable to get to the bottom of why (I include myself in that, but
   I think it reflects more on communications difficulties than a
   shortcoming of Linux mdadm). I am at a loss as to why, given
   those facts, people are still advising Gene to build an entire
   new system out of parts. It makes sense for the use case but not
   for the user. I don't think it's supportable. For this user I
   would have to still stand by my advice of buying an off-the-shelf
   NAS.

I've been into a couple of the largest bookshops in UK in the last few
months - there are fewer and fewer physical books on shelves.

A Debian specific book would be welcome - but the Debian Handbook already
covers much of that. We may end up with refugees from Red Hat distros in
due course but learning apt covers much of that. (If you can use
GNOME in one distro, it's similar in all - and I'm not sure when
Ubuntu last published a handbook, for example).

The big Linux System Administration Handbook - the one with three authors
including Evi Nemeth - is a really good example of something with masses
of good general information but almost nobody has it.

O'Reilly books are primarily online now: I think it would be hard to find
a niche that would fit a new book or a physical book publisher to take it
(and no, I'm not thinking of the average print on demand publisher who
mostly specialises in of out of copyright books, though that might be
an option).

The Red Hat certification market has three or four books: it might be
that maddog and the Linux Professional Institute would be interested
as their courses cover all distros.

Yes, I'd probably buy a copy - I have a physical copy of most of the
Debian books that there are. The most useful at one point was probably
the O'Reilly one which came with a CD.

I do tend to rely on the knowledge and expertise here: Greg - how
would you rate the chances of physical copies of your Bash guides,
for example?

I agree with the reference to a wiki instead (providing sufficient

about software, including OS's, in addition to the need for ongoing 
updates, and, errata documents, is that people always find information 
that should have been included, and, wasn't, and, adding missing

I don't think book are a good way to teach stuff that changes. A wiki
(maybe with paid access, like RedHat does) is much more better than a
book that can't be updated and will be mostly useless with the next
release because beginner don't know which parts are still entirely
adaptable and which aren't.
