Get rid of removed packages in Debian

Mar 4

Posted by ejs in *NIX, My job | Comments off

Every time package is removed via `apt-get remove`, a tiny piece of its configuration can be kept in your system. If you ever need to reinstall the package, this information can be re-used. These packages has status ‘rc’ in the output of `dpkg -l`. But if you want to keep your system tidy and clean, you may want them to be removed.

The miraculous command is

dpkg -l | egrep ^r | cut -d ‘ ‘ -f 3 | xargs apt-get remove –purge -y

Make Samba and CUPS in Debian friends again

Apr 15

Posted by ejs in *NIX | No Comments

I’ve seen a lot of these entries in logfiles recently:

[] printing/print_cups.c:cups_job_submit(656)
Unable to print file to - client-error-bad-request

And the printing is stopped, of course.

The solution is simple:

LANG=en_US.UTF-8 /etc/init.d/samba restart

In short:
/var/log/cups/error_log shows a lot of

E [] Unsupported character set "iso-8859-1"!

CUPS requires UTF-8.
In the case of default login in Debian, the console IS in UTF-8, but is not if you have customized it and use `su` for administrative tasks.

C’ia.
