Delete the last line from your /etc/apt/sources.list

And, I believe you can change 'squeeze' to 'stable', & remain updating the stable version, whatever the name.

Just as an aside; to make it easy on yourself, if you need to re-install again, make your partitioning scheme friendly.

i.e. One partition for swap, One partition for the / (system), & at least another for your /home (&/or data);
then if you have to re-install, only overwrite your / partition. You should, of course, still have backups of your data as well.

If there is problem with one machine not printing correctly I'd be
tempted to think the machines are not identical.


Coincidence! I have the same machine.

Edit /etc/cups/cupsd.conf and put 'LogLevel debug' at the end. Delete or
move /var/log/cups/error_log and restart cups. Print the same PDF from
each machine and compare the logs.

No, this will upgrade any "upgradeable" packages - be it a security
update or not.


You don't upgrade stable to stable, you upgrade certain packages
within the stable distribution - the above command will achieve just
that.


I don't quite get what you mean by Lenny to new Lenny?
Lenny is an unsupported old-stable release.


Lenny to squeeze upgrade is somewhat different, you need to have
entries for both of these releases in you sources.list file(s).

aptitude update && aptitude full-upgrade

will do what you want here. Bear in mind that full-upgrade will remove
packages, i.e. the ones which are in conflict with the new ones.


This is the mistake you made, you've mixed both squeeze (stable) with
sid (unstable release) adding squeeze-backports on top of it.

I'd recommend reading about mixing of stable, testing unstable - stay
away from experimental ;^) - releases and what can you do with APT
pinning. Until then, stick with stable.

In effect that is what I do every day every day (the problem exist for
some time already and now it is getting in my way).

And for those thinking about sacrificing a goat: done that already. It
made the first machine work, not the second one.

Re: how to update Debian OS properly

Ralf Mardorf — 2012-05-25T12:49:26

You're issue is related to the sid repository. If you need something
from sid, then uncomment it and after that comment it. Don't feel secure
using pinning.

You can name the repositories "stable" instead of "squeeze", so it will
use "stable" what ever Debian "stable" is named.

Hi,

I had a similar problem long time ago I don't remember if the error
message was the same....

But.... I solved it stopping and unplugging the printer for a while
(30 sec should be enough)

Its sound silly but it worked. :)

Install stable and stick with it. Do not be tempted to alter sources.list
in /etc/apt/


This is very, very unlikely to happen. If it did, someone would notice
and provide you with a fixed package.
 

Forget about it. Re-install stable.

Wheezy printing problem: 2 identical (?) machines and 1 does notprint PDFs

Joost Kraaijeveld — 2012-05-25T12:39:01

Hi,

I have 2 identical Wheezy machines: they both have the same packages and
the same versions for those packages Wheezy, up to date as of this
morning). The configuration files in /etc/cups and /etc/foomatic are
exactly identical. Both machines should print to a network printer
(HP2200 DTN). I use Cups and Foomatic, and the recommended "HP LaserJet
2200 Foomatic/lj5gray" driver (the postscript driver has the same
behaviour).

Both machines print the Linux test page without problems. But one
machine cannot print PDFs while the other one prints them without
problem, be it a little slow (i.e. compared to the Windows machines that
use the same printer). The problematic machine prints a PDF file as an
almost empty pages with the following text:
"PCL CL error 
    Subsystem: IMAGE 
    Error:     ExtraData 
    Operator:  ReadImage 
    Position:  7"
I have re-installed/purged/rebooted etc. and nothing helped so far.

Does anyone recognises this problem? Which *machine-dependent* files
exist and in which directory are there, after an
installation/configuration? Anyone any ideas?

TIA

Re: how to update Debian OS properly

Muhammad Yousuf Khan — 2012-05-25T12:37:16

ok it will only update the security patches, no matter if what ever i
write in source.list?

one more question. for example. if i wanted to upgrade. but only to
stable version not to unstable or testing. then what could be done to
achieve this. if there is no stable version update then it shouldn’t
download anything from servers.

what i want is not just security patch but also OS to OS upgrade but
only stable releases
for, example. lenny to new lenny (but stable version)
for,example Lenny to Squeez (but stable squeez version)

how it is possible?

AFAIK yes, Clonezilla should be ok.


If you don't sync, than yes, at least for Linux you'll restore exactly
what you had before, at a explicit date. I suspect XP does a kind of
sync and I suspect it will be possible for Linux too, but if you tar
your Debian or use Clonezilla to do a complete image, nothing could go
wrong.

This doesn't make sense; if the sshd is instructed to disable password

fail.

Re: Mounting local filesystem failed on boot

Roger Leigh — 2012-05-25T12:21:06

No, the bug was fixed in unstable in January/February.  It's still
present in stable.  I haven't had independent confirmation it was
fixed, so it's been left open for the time being, but should probably
be closed.  It's possible that this could be fixed in a stable point
release, but AFAICT it's purely cosmetic--while it says it failed to
mount the local filesystems, it mounted everything except /proc.
If fixed in a point release, we could also need to update
initramfs-tools as well.

now this snapshots point raising one more question in my mind.
did you means snapshots like XP and Other windows OS supports. for

apache , samba or anything. and after installing , at the end i
realize that i messed up the whole box then i can revert my system
back to that particular snapshot and i will be at the old stage. can i
use snapshot in this context ( sorry for the newbie Questions but i am
confused with Microsoft and Linux as there are same services in both

Re: how to update Debian OS properly

Ralf Mardorf — 2012-05-25T12:17:35

"things" for your current install might be /home only. Perhaps xorg.conf
and some other files, using cp -pr while you're root. But in the future
completely backup using e.g. tar. Note, if you sync, you anyway might
lose data, since you might notice some issues after doing several
backups and not already with the backup that did cause an issue.

Re: how to update Debian OS properly

Kumar Appaiah — 2012-05-25T11:42:53

If security is your concern, you ought to be running "stable" as
opposed to testing. If you run stable, then ensuring that
security.debian.org is listed in the /etc/apt/sources.list will fetch
security updates.


I'd advise you to subscribe to the security mailing list of the
projects which you run on your machine whose security issues you are
concerned about.

Read this for further details and ideas: http://www.debian.org/security/


This is a little complicated and one could end up hosing one's
system. I'd advise you to back up things and do a fresh install of
squeeze.

HTH.

Read below [0].


aptitude update && aptitude safe-upgrade [1]


There are no "patches" like in Windows. Patches in free (open source)
software are for source code [2].

Upgrading a package you effectively installing a new version of the
software.


You can always install an older version of the package.

[0] It seems like you had several entries in your sources.list file(s)
- post the content of your file here.

[1] safe-upgrade will only upgrade packages and won't remove any other
ones

[2] yes, I know, you can have binary patches as well
