apt-get autoremove Anonymous 2015-11-24 22:32:16 No.14304

So, apt says I have a lot of "unneeded" packages, such as lightdm, everything xfce4 related, my music player, etc. A lot of the packages actually aren't needed, but I can't tell which is which. Can you help Lains?

I did this a while ago and it took out my wifi manager. You should do them individually.

You might want to write everything important on a list, do sudo apt-get autoremove and the install the important bits again.

apt-get install the packages you need

they will go to manually selected[1] themselves and therefore not get fuarrrking autouninstalled

[1] installed and not as a dependency of some other packages

>>14316
no! what the fuarrrk

PS: from what i hear dist-upgrade can break things too and is therefore not meant to be in the update cronjob of servers

I have the same problem, why does this happen?

This is a guess, but maybe unneeded means no package depends on it, and it was not installed by the user. So a package that came with the OS, or was a dependancy for a previously installed program.

apt-get install deborphan

deborphan is a super useful program to finds packages that have no packages that are unrequired by other program and therefore safe to remove.

here's a good sets of commands to clean up a debian system (run as root).

//Remove all orphans
deborphan --guess-all | xargs apt-get -y remove --purge

//clean up
apt-get autoclean
apt-get autoremove

it may have been that you removed a meta-package and now apt-get considers them orphaned.

>>14514
this is a good program but again use it with extreme caution. it has a graphical front-end called gtk-orphan. See what it lists and then look the package up and decide if that's something you do or don't need.

I agree, you'll end up with unwanted removing with the --guess-all option. It's rather safe by default though. I use it like this :


aptitude purge `deborphan`

And never got any problems so far. The aptitude front-end is also good to spot unwanted packages and remove them.

Just use:

apt-get --purge autoremove

You can also purge packages that were only removed with:

dpkg -l | awk '/^rc/ {print $2}' | xargs sudo dpkg --purge

did you even read the OP? if he tries to remove everything marked as orphaned he will delete what are probably system critical packages

Anon, you removed something like ubuntu-desktop or fluxbuntu-desktop, didn't you

A lot of those are definitely possible to remove (all the -dev packages, out of date libraries, etc), but just reinstall the meta package you stupidly removed.
