I'm fairly new to Ubuntu (respectively Kubuntu) and Linux in general. Yet, some thing is causing trouble to me. Excuse me, if this has been answered before, but I somehow can't put together those pieces in a way that I can actually understand.

So, I've recently installed the kubuntu-restricted-extras (via sudo apt-get install kubuntu-restricted-extas) for playing MP3 files, watching DVD movies etc.. There's one thing yet that has kept me bothering for almost two weeks now:

Just in theory: Assuming I want to remove those packages kubuntu-restricted-extras is refering to... how am I supposed do actually do this?

I've heard about sudo apt-get --purge autoremove <packagename>, but this one's just removing the metapackage itself - at least for me.

It's not that I'm annoyed by having these packages installed on my PC, yet I'm very interested in learning how to deal with this "autoremove" function in general.

For another instance, 'apt-get autoremove --purge quassel' leaves packages like quassel-data installed on my machine. Am I doing something wrong?

Thanks for your help!

PS: While writing, I came up with another question, this one's rather small though. I know, there are many PPAs out there, often containing additional or newer versions of various pieces of software... Assuming I want to remove one of these additional sources with, let's say, an unstable mesa build, how do I revert those packages like xorg, mesa, etc. (Let's say I've added this xorg-edgers PPA) back to the versions in the actual Ubuntu repositories? That'd also be great to know.

Again, thanks for your help!

  • Regarding the PS, see http://askubuntu.com/a/313/158442. – muru Jan 21 '15 at 21:10
  • Okay, that makes sense to me, thanks :)

    There's just this other thing that's bothering me. Let's see if someone knows a solution.

Logs

Ubuntu community: https://help.ubuntu.com/community/LinuxLogFiles

The apt log: /var/log/apt/...

The dpkg log: /var/log/dpkg.log...

Keeping own logs - the logsave

LOGSAVE(8)                                  System Manager's Manual                                  LOGSAVE(8)

NAME
       logsave - save the output of a command in a logfile

SYNOPSIS
       logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION
       The  logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output
       to logfile.  If the containing directory for logfile does not exist, logsave will accumulate the  output
       in memory until it can be written out.  A copy of the output will also be written to standard output.

At here

When installing/upgrading/removing something I will use the logsave to save the output to the human readable file.

If I want to remove the 'kubuntu-restricted-extras' I would look the log file:
