How to clean up orphaned packages in Ubuntu?

Question

linux

Hello!
At the moment I use Arch Linux and, in principle, I am satisfied. I recently used Ubuntu 14.10, I liked the Unity shell, and the distribution itself too. I wanted to put it on the laptop.
Now the crux of the problem: apt-get. How can I clean orphaned packages here? How to remove configs for unused packages? I was looking for answers on all sorts of communities, I met terrible things like:

# apt-get remove --auto-remove --purge часть_имени_пакета*

Is it possible to do this through aptitude or something else? And then I set up the packages, removed some, and some of the unnecessary dependencies are lying around in the system, and there is no way to remove them ...

Answer 1

Well, in general, it's not such a terrible thing. You can do this:
Then see which package settings are left:
And you can then remove them using dpkg --purge or apt-get remove --purge
You can also use deborphan
Or even like this:

dpkg -l | grep ^rc | awk '{printf $2}' | xargs dpkg --purge

Deborphan has already been written about.
