Purging installed programs

[pooky2483]

I have a few programs I want to get rid of but don't exactly know how to do it properly.
The programs are;
Azureus Vuze
Peerguardian (PGL) I think
Compiz (I don't use the Desktop that uses Compiz)

I also need to repair Ubuntu One as I had a go at removing it a while ago but only recently decided I wanted it back so I tried to reinstall it from the repo but it looks like it hangs and doesn’t do anything.

Synaptic Package Manager is your friend.

Vuze & Compiz show as not installed
PGL shows up on screen when rebooting (or something similar)

Ubuntu One shows as installed but doesn’t work

OK, it should be safe to remove/purge Vuze and pgl

pgl .. as that was added with from a PPA, the easiest way would be to use ppa-purge to remove all changes made by adding that PPA:

Code: [Select]

sudo apt-get install ppa-purge

then

Code: [Select]

sudo ppa-purge ppa:jre-phoenix/ppa

Vuze ..

Code: [Select]

sudo apt-get remove --purge vuze

then you can remove any orphaned dependencies with:

Code: [Select]

sudo apt-get autoremove

BE CAREFUL with that last command .. read what's going to be removed BEFORE accepting the changes, and make sure it's not going to remove anything you need.

Compiz ..
Though it IS possible to remove compiz (as long as you aren't going to use Unity or Unity 2D) .. I wouldn't advise it, unless you know what you're doing .. it will definately take Unity and Unity 2D with it, and also the ubuntu-desktop meta package.

I *gather* it's safe as long as you have the gnome shell and gnome-session-fallback installed (as they use Mutter), but I've never tried .. so on your head be it

I'm also not going to give instructions how to do it .. as I don't post things I'm not sure are safe .. but you can take a look here if you wish:

http://askubuntu.com/questions/73610/since-ive-moved-to-the-gnome-shell-is-it-safe-to-remove-compiz
and
http://askubuntu.com/questions/87287/can-i-uninstall-compiz-if-only-using-gnome-shell

As I said .. it's on your head if things go wrong .. personally I'd advise you to leave it alone, if you're using the Gnome desktop, it shouldn't be using any system resources anyway AFAIK.

Ubuntu One shows as installed but doesn’t work

If vuze and compiz show as not installed in Synaptic .. then they are most likely not installed (or weren't installed from the repo's) .. what makes you think they are installed ?

I also need to repair Ubuntu One as I had a go at removing it a while ago but only recently decided I wanted it back so I tried to reinstall it from the repo but it looks like it hangs and doesn’t do anything.

See here:

hopefully that will apply to 11.110 as well.

They were installed but recently uninstalled. I was unsure of 100% removal of VUZE.

[Mark Greaves (PCNetSpec)]

if you want to be 100% sure of removal of the Vuze configs as well

reinstall it, then remove it with the --purge option added.

you can check if the configs are still present with:

Code: [Select]

dpkg -l | grep vuze

if what's returned starts with
rc
vuze was removed but the config files are still present.

Or you can ignore them .. they will be very small, and inactive.
