  just me and a preference to err on the side
of caution when dealing with devices that might
alter a very basic thing.

  maybe, if they just want to see what it says
it will do.

  also, consider that bugs do happen and sometimes
a dry run switch will discover them before it does
the actual write to the device.

  yes, always a good idea.

  mostly the idea is to prevent "wrong device" or a fumble
finger kind of error.  with some things i know it is ok to
ask for forgiveness instead of asking for permission, but
when it comes down to devices and partition tables i put 
them in the more paranoid group.

  it is very useful to think about for me too
at the moment i'm considering how to set up one
or two USB sticks and getting them ready for 
the stretch installer.  i will likely need to 
use them for a new machine in the next few weeks.

  saying what kind of experience you have so far

  because you mention a learning curve, i'd just assume
that you won't have this ready to go by then...  not
because i doubt you can do it, i just have no idea, so
i'm always willing to err on the side of giving myself
enough time to make sure things are covered that need
to be covered.

  Things To Do List:

  i think that you are seeing the final months, but with
over 200RC bugs it will likely be longer.  however, perhaps
some miracle bug squashing parties will happen and it will
go sooner.  anyways, whatever does happen i don't think the
final shape of the release is going to change to a huge
degree now.  and noting your comment about not wanting to
deal with configuration changes frequently.  updating from
Jessie to Stretch will be more work IMO.

  no, just go with Stretch as it stands now and follow along
as you are learning.  it will be a good way to learn some
of the basics you'll need.

Debian was the first distro to make promises that you could
upgrade in place. It's very good at that.

I would recommend that.

I don't know, no. Alternative web mail clients: Roundcube is packaged
in Debian and works pretty well; Rainloop is not packaged in Debian and
also works pretty well.

You're going to end up discovering that this is a problem in IP
assignment, routing, forwarding, or something very similar.

What masquerading are you doing? What IP forwarding? What
routing entries are present?

Future upgrade from Stretch RC2 to release

[Niclas Arndt]

Hi,


I am considering changing from OpenSUSE to Debian for my e-mail server but I 
expect a learning curve. I'm sorry if my questions are basic, but please bear 
with me.


* Is there any chance that Stretch will be stable by 2017-05-16 when OpenSUSE 
Leap 42.1 goes EOL?


* Is it advisable to install Stretch RC2 today, start configuring the server, 
and later upgrade to the release version before going into productive use? Is 
there a risk for problems with such an approach?


* Should I instead install 8.7 and later upgrade to Stretch? The only reason 
for me to look for an alternative to OpenSUSE is the short productive life of 
each release and too frequent configuration changes.


* Does anybody know if Squirrelmail is working properly with PHP7 now? (I know 
that this is off-topic.)


Grateful for your input. Thanks in advance.

Wan/Lan problem

[Mike McClain]

Howdy,
I have a WAN/LAN challenge I'm hoping for help with.

I'm runniing Debian 7.11 on a Pentium 3 with 250MB ram.

mike@/deb7:~> uname -a
Linux playground 3.2.0-4-686-pae #1 SMP Debian 3.2.84-2 i686 GNU/Linux


The situation is this:

 phoneeth0 eth1
AT|   ||   ||   |---|   |
AT modem/ Linux my Win2K
router   box router   box

When eth0 is up and eth1 down,
the Linux box can access the web.
'ping ATTrouter' works.
When eth0 is up and eth1 up,
the Linux box can not access the web.
the Win2K box can access the web.
the Linux box can not access the Win2K shares.
'ping ATTrouter' fails.
'ping -Ieth0 ATTrouter' works.
When eth0 is down and eth1 up,
the Linux box can access the Win2K shares.
When eth0 is down and eth1 down,
it's quiet.

The ATT router is set to 'Pass Through' giving the Linux box the ATT
router's IP address.
The Linux box is set to use DHCP.
This might explain why I loose the LAN connection when eth0 up.

Why can the Linux box not see the web while the Win2K box can?

I've not found or at least recognized the problem in the HowTo's.
Pointer's or suggestions?

Thanks,
Mike

Re: UID mismatch across systems

[Ross Boylan]

I made some discoveries on a test system:

root@IDTest:/etc# date; usermod -u 204 Debian-exim
Tue Mar 28 15:01:19 PDT 2017
usermod: user Debian-exim is currently used by process 664

and this left everything, including the running process and passwd untouched.

So I don't have to worry about what happens when I usermod the id when
a process is running; usermod won't do that.  Of course I can still
edit the passwd file by hand, but by itself I assume this will leave
the uid of existing processes and files unchanged (except they will
display differently in ls or ps).

Also, after I stopped exim4 and executed the usermod command above,
only the passwd file changed.  So that's easy enough to do offline.

As documented, usermod changes the uids of files in the user home
directory and below, but leaves others untouched:
root@IDTest:/etc# find / -uid 104 -ls

He hecho un "fsck.ext4 /dev/sdg1 y me ha detectado algunos bloques

Ahora cuando ejecuto esta bien.

¿Se supone que me puedo fiar del disco? ¿O mejor lo cambio? No tengo

It's worth stressing on this point, since I've the suspicion that there
is a misunderstanding on your part, Daniel: the charge controller isn't
that external brick: that is probably just a more or less dumb power
source. The charge controller is buried somewhere in your laptop (as
Joe puts it, on the laptop's motherboard).

perhaps you can use yad, a fork of zenity, with the tail option:

Yes, I just looked at the earlier lines that I'm familiar with, viz.

POWER_SUPPLY_ENERGY_FULL_DESIGN=6000
POWER_SUPPLY_ENERGY_FULL=4892
POWER_SUPPLY_ENERGY_NOW=1879

I'll cross my fingers for you. Please do likewise as these are
the figures from one of my laptops:

Charger in:
POWER_SUPPLY_CHARGE_FULL_DESIGN=380
POWER_SUPPLY_CHARGE_FULL=872000
POWER_SUPPLY_CHARGE_NOW=380

Charger out:
POWER_SUPPLY_CHARGE_FULL_DESIGN=380
POWER_SUPPLY_CHARGE_FULL=872000
POWER_SUPPLY_CHARGE_NOW=828000

IOW my baseline after 8 years is about 20% capacity.

DNS queries return all the possible entries (even for round robin.) The

The entries in the RR were returned in the above dig command. Those are the
only two  records for ftp.us.debian.org. 2600:3402:200:227::2 was not
part of the round robin entries.

Here is 10,000 queries for the  records of ftp.us.debian.org:

% for f in `seq 1 1`; do
dig ftp.us.debian.org  +short
done | sort | uniq
2610:148:1f10:3::89
2620:0:861:1:208:80:154:15

I (always) get the same two addresses.

Looking at the v4 systems for ftp.us.debian.org:

% dig ftp.us.debian.org +short | sort
128.30.2.26
128.61.240.89
208.80.154.15
64.50.233.100
64.50.236.52

% for host in `dig ftp.us.debian.org a +short | sort`; do
echo "$host => $(dig -x $host +short)"
done
128.30.2.26 => mirror-0.csail.mit.edu.
128.61.240.89 => debian.gtisc.gatech.edu.
208.80.154.15 => sodium.wikimedia.org.
64.50.233.100 => ftp-nyc.osuosl.org.
64.50.236.52 => ftp-chi.osuosl.org.

and the v6 systems for ftp.us.debian.org:

% for host in `dig ftp.us.debian.org  +short | sort`; do
echo "$host => $(dig -x $host +short)"
done
2610:148:1f10:3::89 => debian.gtisc.gatech.edu.
2620:0:861:1:208:80:154:15 => sodium.wikimedia.org.

Curiously, when running various apt commands my system does seem to want to
connect to:

% dig  ftp-nyc.osuosl.org. +short
2600:3404:200:237::2

% dig  ftp-chi.osuosl.org. +short
2600:3402:200:227::2

Even though those systems are not listed in the round robin set for the
 records of ftp.us.debian.org.

I'm puzzled.

Well, I have _not_ looked further than the head, and I'm also unable
to look at amd64 on wheezy, but i386 will do for my purpose.
Here's your post again:

Now you can see why these two lines appear in your post:

libc6
2.11

but you won't find version 2.11 on you system (unless you're running
aqueeze); you've got 2.13. So when you venture further into the body
of your strings file, and you come across

package-name
version

how are you going to know whether it's the version of a package,
or just some casual mention under one of the other headings?
You call that coherence?

No, the trickiness is because it's binary: it's organised for the

Apparently ftp-chi.osuosl.org works for me, can you reach other IPv6

Thank you for sharing these experiences. In my previous email I was
talking about a full discharge because that's what I thought happened
when I saw the KDE charge indicator after I plugged in the charger once
the notebook shut down abruptly because I did not have enable the
"Enable Power Management" option of KDE. That's why I thought that it
would avoid that situation happens again

I was observing these values:


$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
(...)
  battery
(...)
percentage:  37%
capacity:81,5333%
(...)


But I'm not sure if that will be indicator of something. "Percentage"
seems to be the battery charge level. Looking at the upower
documentation I found this [1]:

The "Percentage" property: The amount of energy left in the power source
expressed as a percentage between 0 and 100. Typically this is the same
as (energy - energy-empty) / (energy-full - energy-empty). However, some
primitive power sources are capable of only reporting percentages and in
this case the energy-* properties will be unset while this property is set.

The "Capacity" property: The capacity of the power source expressed as a
percentage between 0 and 100. The capacity of the battery will reduce
with age. A capacity value less than 75% is usually a sign that you
should renew your battery. Typically this value is the same as
(full-design / full) * 100. However, some primitive power sources are
not capable reporting capacity and in this case the capacity property
will be unset.

I was comparing the values with those of the original battery:

But what difference would that make ?
If the program thinks it's not ok, then it will refuse.
If it thinks it's ok, then shall the user refrain nevertheless ?

Of course it's safer to know what is on the stick or to inspect

ipv6 apt issue

[Matt Zagrabelny]

Greetings,

I'm hitting an IPv6 snafu.

I've got a dual stack host and when doing various apt-y things I attempt to
connect to:

# apt update
0% [Connecting to ftp-chi.osuosl.org (2600:3402:200:227::2)

but it hangs and doesn't seem to complete its connection.

If I look at my sources lists:

% grep http /etc/apt/sources.list.d/*.list | sed -e 's/.*http:\/\///' | uniq
ftp.us.debian.org/debian/ experimental main
ftp.us.debian.org/debian/ jessie main contrib non-free
ftp.us.debian.org/debian/ sid main contrib non-free
ftp.us.debian.org/debian/ stretch main contrib non-free

I don't have an /etc/apt/sources.list file. To my observation, my host
should only be connecting ftp.us.debian.org.

Which has the following v6 addresses:

% dig ftp.us.debian.org  +short
2610:148:1f10:3::89
2620:0:861:1:208:80:154:15

So, where does the above ftp-chi.osuosl.org (2600:3402:200:227::2) coming
from?

Thanks for any pointers!

Yes, but it is unlikely that a schematic diagram of the laptop
motherboard will be available. It shouldn't be too hard to locate the
parts used in charging, but if the main IC is faulty, it may not be
available in your part of the world. Less of a problem these days, as
many Chinese parts can be sourced directly, but some years ago, my son
blew up an electronic switch on a MB by seating a memory PCB badly. I
could identify the IC, but was unable to find anyone, anywhere in
Europe, selling it. Finally, you need someone happy to make repairs on
a laptop motherboard. It may not work out cheaper than the battery.

Just that supplying power to the laptop and supplying charge to the
battery are likely to be separate functions, and if one works, that
proves nothing about whether the other works.

Lots of contacts. It is possible that the battery electronics can tell
if it is correctly seated in the right model laptop, and will not supply
power if that is not the case. For your safety, of course.

You are nearly there. Any combination of preseed directives can be used
as boot parameters. For example: netcfg/get_ipaddress=192.168.1.42.

AFAIK, not on the website. You can generate all the preseed options for
yourself. Search the wiki for "preseed".

  if you don't know where the executable is coming
from you can use the command:

  note: some executables are in /usr/bin, some are

  which directories are used/searched will depend upon

But in any case, whether the problem is in the charger or the battery, I
suppose that to solve the issue I will have to change the part. I
suppose if the problem is in the charger, the cost will be less compared
to a battery.

If I understood correctly, I think that here you was suggested that it
could also be a problem related to another internal component of the
notebook that diverts power from the charger to the battery for its charge.

 Perhaps the ultimate test is going to a business where they have
 original Lenovo components, ask them for a new battery to test it
 at the moment with the notebook and, if all goes well, then buy
 it.

Yes, it is good that they have had that good predisposition. In fact,
when I talked to them on the phone, I told them that if I saw that when
I plugged in the charger, the charge led behaves correctly, I could
assume the issue was on the battery and that would make the test a
little quick. But the person I spoke insisted on doing a full load cycle
so they would be reassured that everything works fine. Going there and
back takes me at least three hours (plus the the time awaiting for full
charge of the battery) so the trip would be a pain (not to mention go to
leave the notebook for the test, go back, and go later for it). The

The reason to start this thread was about "gparted". We saw output of
"fdisk" and "gdisk". All three are for command line and/or text dialog.

The desktops will surely have their own graphical tools.
I expect that they handle partitioning and also file system creation.

Well, i'd need to decide for a filesystem type anyways.
If it's for exchange of files with MS-Windows or Mac, then mkfs.msdos
or mkfs.vfat.
If it's for Linux only with need for linux-ly filenames and file

The words "mkfs.msdos", "mkfs.vfat", "mkfs.ext2", "mkfs.ext3", "mkfs.ext4"

Re: gestion de carga y visitas a un servicio.

[Dixan]

Puedes crear un registro A para cada host con el mismo nombre y reducir
su TTL de esa forma por cada consulta se rotara la ip de la pagina a la
que se conecta el usuario (round robin) esto no tiene en cuenta su
ubicación, si necesitas responder su consulta con una ip especifica
basado en su ip de origen puedes configurar en bind varios views por
pais(es) (split-horizon) y un view predeterminado para todos los que no
tengan una declaracion especifica a su ubicacion geografica, esto lleva
un poco de trabajo. Si el nombre de los hosts es el mismo que el
certificado SSL no debe dar problemas. Si alguno de los servidores Web
esta saturado el DNS no tendrá conocimiento de eso y continuara dando su
ip asi que tendrias que observar la carga del servidor con algun script
y basado en eso generar un .htaccess que redireccione las peticiones
entrantes al otro servidor (Esto es solo una idea, estoy seguro existe
una mejor solucion).

Deb-Installer: Possible to set IP using a boot parameter?

[Ron Leach]

List, good afternoon,

Does anyone know whether there is a Debian-Installer boot parameter 
that enables a specific, static, IP to be set for use during the 
installation process?


I've checked the Installer guide, s 5.3 boot parameters [1], where a 
parameter to disable DHCP autoconfig is described but I'd like to be 
able to set a specific IP as well.


(The reason for wanting this, if possible, is that I will have to 
install onto a bare motherboard and disks, without screen or keyboard, 
and I'd like to control this install over SSH (if the installer would 
also start it) from another machine.  I have seen that this can be 
arranged using a pre-seeding file [2, 3] - which I found a bit 
complicated - but I am hoping there may be a simpler way for my case. 
 ... Perhaps not, albeit.)


Is there a definitive list of all the installer's boot parameters and 
values, anywhere?  Or are the parameters literally those described in 
s 5.3 of the installer guide?

Well, I actually checked further down than the head (let's refer to it
as the body) and I did systematically discover version and package
names, so I think the output is more coherent than you're letting on but
who cares?  We know what is in those files (thank you David #1--yes I'm
relegating you to David #2, sorry). That is the point of my post in the
first place. It is not true what you posited, that it is tricky to know
what those files contain. We know (although it is not documented in the
man page(s) because people in the know figure these descriptions too
low-level for mortals like us. Maybe therein lies the trickiness.

They contain exactly what David #1 said they did, I assume, as I have no
good reason not to believe him (given that he's a bona fide authority on
the matter in his role as an APT contributor).

But in the context of the OP why you couldn't copy the two files from
the first machine after the cds had been scanned and then copy them back
to the second machine in order to avoid rescanning I don't know.

Looking at my notes: The key ID in questions refers to a subkey. apt
seems to not use them when present in files in /etc/apt/trusted.gpg.d/.
But Googles Release file is signed by multiple keys, so this message
should be benign.

When you look in the mirror, it doesn't exchange left and right,
but fore and aft. To make a mirror exchange up and down, lay it

Thanks very much for your reply. I took the file I had previously 
downloaded, and had been placing in /etc/apt/trusted.gpg.d/ , and ran 
apt-key add on that file. It responded "OK", and after that aptitude 
update runs with zero errors.

Putting the file in trusted.gpg.d didn't work, importing it using 
apt-key add did. Given Sven's experience to the contrary, I am at a loss 
to explain that.

But what is important to me for now is that, at last, both problems from 
this thread are resolved and I get no errors when I run aptitude update. 
Thanks very much to everyone who contributed.

Probably my error. I forgot the many architectures supported by Debian.

So please download:

If you do not have program /usr/bin/cc yet, then install package
"build-essential", which provides the equipment for the C language.

Dans mes diverses notes j'ai retenu ceci pour /etc/hosts
127.0.0.1   localhost127.0.1.1  nom-serveur.domaine 
domaine  pop.domaine  smtp.domaine
D'ailleurs si quelqu'un sait m'expliquer pourquoi attribuer les noms
"personnalisés" sur 127.0.1.1 au lieu de 127.0.0.1, je suis preneur.
J'ai remarqué que si on ne remplit pas le fichier correctement la
commande hostname peut s'en trouver perturbée. Je conseille donc de
vérifier après le changement que hostname -d, hostname -s et hostname
-f donnent un résultat cohérent, sans lenteur.

Pour ces erreurs je n'ai pas encore pu fouiller mes notes; mais un coup

donc il y a potentiellement un réel souci sur le SSL ou bien sur

I'd guess there's a difference between Thomas's processor architecture
and yours. For a first stab, try those:

  file /home/richard/Downloads/make_isombr_part
  file /bin/ls

(Yes, I know Richard's box can be multiarch, but that'd be the next
stab :)

Can it be your system is equipped with Debian for architecture i386 ?
I forgot to mention that my system is amd64.


> Operator error or other?

Probably my error. I forgot the many architectures supported by Debian.
I should have advertised building from source.

So please download:

  http://scdbackup.webframe.org/make_isombr_part.c

MD5: 85e89cec6173e889693e8466d7cad763

If you do not have program /usr/bin/cc yet, then install package
"build-essential", which provides the equipment for the C language.

To build your own binary, do in the directory where you have the
file  make_isombr_part.c :

  cc -g -Wall -o make_isombr_part make_isombr_part.c

This command should end quickly without any messages.
If messages appear, then please show them.
If all is well, a new file
  make_isombr_part
is supposed to have emerged and to have rx-permissions at least
for its owner. That's your executable binary.

Sorry for the inconvenience.


Have a nice day :)

Re: DD bs=4M option on USB mem-stick creates false format

[Thomas Schmitt]

Hi,

i wrote a small program which shall make a USB stick with isohybrid ISO
more digestible for partition editors by removing all partition tables
except MBR partitions.
It then creates a new partition in the first MBR partition slot which
is found with block count 0.

  usage: ./make_isombr_part file_path partition_end partition_type

 Creates a partition in a free slot of an isohybrid MBR in an ISO.
 Removes GPT and APM signatures if present.
 file_path must lead to a file or device with isohybrid ISO.
 partition_end tells the number of 512-byte blocks of device.
 partiton_end value "auto" means full number of device blocks.
 partition_type is a hex number in the range of 00 to ff.
 Type examples: 83 = Linux , 0c = FAT32 , 17 = Hidden NTFS

Binary compiled on Debian 8 (you may need to give it x-permission after
download):

  http://scdbackup.webframe.org/make_isombr_part

MD5: 4856af2c1b50a775325a3e6c09d7d9bc

Source code:
  http://scdbackup.webframe.org/make_isombr_part.c

The argument "auto" currently works only on Linux kernels.
On other systems one has to give the block number explicitely.



See a test run with rescatux ISO on /dev/sdc (any current Debian i386
or amd64 ISO would be suitable, too).

Still less dangerous than manipulating /dev files as superuser is
to give the world temporary permission to the one stick in question:

  $ sudo chmod o+rw /dev/sdc

(The program is supposed to refuse if it does not find an isohybrid ISO.
 But better do not bet on those safety measures.)

Let the program remove APM and GPT and add a MBR partition:

  $ chmod u+x ./make_isombr_part

  $ ./make_isombr_part /dev/sdc auto 83
  Note: Storage capacity of '/dev/sdc' : 3915776 blocks
  Note: Wrote MBR partition slot 3, type 0x83, start 1374208, blocks 2541568
  Note: Removed APM signature
  Note: Removed GPT signature at block 1
  Note: Removed GPT signature at block 1374207

Afterwards, fdisk reports the new partiton table:

  $ /sbin/fdisk -l /dev/sdc
  Disk /dev/sdc: 1.9 GiB, 2004877312 bytes, 3915776 sectors
  ...
  Device Boot   Start End Sectors  Size Id Type
  /dev/sdc1  * 64 1374207 1374144  671M  0 Empty
  /dev/sdc2   1297212 12986191408  704K ef EFI (FAT-12/16/32)
  /dev/sdc3   1374208 3915775 2541568  1.2G 83 Linux

When done, exclude the world from directly reading and altering the stick
content:

  $ sudo chmod o-rw /dev/sdc

Best unplug the stick and put it in again, so that the operating system
takes notice of the new partition table situation.



It would be interesting to see how various partition editors react on
this state of the USB stick. Can they reduce the size of partition 3 ?
Can they remove partition 3 and add on new one ?



Have a nice day :)

I give in! Your ULD package doesn't work for you on unstable. Let us see
how mine goes on.

1. Go to http://www.samsung.com/uk/support/model/ML-1910/SEE and download
   uld_v1.00.06.tar.gz.

2. Decompress and unpack the file with 'tar zvxf uld_v1.00.06.tar.gz'.

3. cp uld/i386/rastertospl /usr/lib/cups/filter/.

4. chown root.root /usr/lib/cups/filter/rastertospl.

5. cp uld/noarch/share/ppd/Samsung_ML-191x_Series.ppd /usr/share/ppd/custom/.

6. lpinfo -m | grep ML-191x.

7. lpadmin -p ML191x -v file:/dev/null -E -m 
lsb/usr/custom/Samsung_ML-191x_Series.ppd.

The last five steps are done as root.

Now (as root again)

8. cupsfilter -p /etc/cups/ppd/ML192x.ppd -e -m printer/foo message.txt > 
out.prn 2>log.

log and out.prn have been compressed and attached to this mail.
Uncompress with gunzip. Note that the log shows all filters being run
successfully. As far as I am concerned, cupsd and the filtering system
have worked well. message.txt contains a secret message for you.

out.prn is a file which can be sent directly to the Samsung printer.
But I haven't got such a printer, you say. Ah, but *you* have. So do

 cat out.prn > /dev/usb/lp0

You can now reveal the message to everyone.

An invitation: any of the hundreds of list readers with a USB connected
Samsung printer which accepts SPL can have fun trying to print the file
too.

Do NOT *EVER* do this. Importing a key from the keyservers just because
apt says it does not know the ID is wrong. 

You might get MitM'ed right now (in this case we know this is the ID of
Googles key, but my argument still holds in general) and installing the
attackers forged pubkey is exactly what he would want.

Only ever install keys from trusted sources into your apt's trusted
keyring.

Because the library is called "libopenjp2.so.7":
https://packages.debian.org/sid/amd64/libopenjp2-7/filelist

Why is the library named like that? You have to ask upstream about
that. I smell a SO name conflict in there somewhere.

> Why is/was there a "libopenjpeg5" package?

Was: because it was the name of the library in the past. Debian Jessie
is the last Version of Debian containing both libopenjpeg2 and
libopenjp2.

Is: There is not, at least in Testing and Unstable. If you still have the
package, then maybe because you have libavcodec-ffmpeg56 or libavcodec56
installed, both still depend on it.

debian reinicio constante

[franiortiz hotmail]

Hola a todos pues algo muy raro, sintoma : cuando arranco mi particion 
debian de 3 años de uso en lenovo m55, se apaga-reinicia constantemente.
causa: en este orden cambios hechos :
1- instalar psensor
2- redimensionar y mover particion / (un disco, 2 particiones:xp+linux/)
3- actualizar
Al ppio pense que seria por temperatura, asi que limpie bien el pc, 
apenas sucio.
luego pense por discos o ram, asi que pase memtest, satisfactoriamente, 
los discos los miro con crystaldiskinfo y estan perfectos, por cierto el 
viejo xp y los livecd van perfecto, asi que descarto hardware.
4- supuse que al mover la particion (/) algo salio mal, algo que ni fsck 
encontro, que tambien probe. asi que reinstale 
debian-live-8.7.1-i386-standard-non-free.iso con lxde-core, lightdm y 
nada mas, todo actualizado y sorpresa la mia se vuelve a reiniciar solo 
con apenas paquetes en version stable.
5- empiezo a pensar que el fallo fue actualizar, voy a probar con la 
version 
https://cdimage.debian.org/cdimage/archive/8.6.0-live/i386/iso-hybrid/debian-live-8.6.0-i386-standard.iso
 
, a ver si consigo instalarla sin actualizar y que no se reinicie, pero 
si es asi, me las veo mal sin poder actualizar.
6- Esto es un bug?
Alguna idea? necesito volver a tener mi debian en este pc, que me estoy 
viendo obligado a usar mocosoft
Gracias, un saludo
