I've had made a huge mistake by wiping out every VLC folder from Ubuntu 12.04. I tried to reinstall it, but it doesn't work.

I tried installing it by command line and it seems to work: however, when I run the vlc command, it says VLC is not installed.

If I try to install it again, it tells me VLC is already at the latest version.
Now I can't run VLC any more and can't figure how to fix it.
Thanks in advance!

I ran these:

sudo apt-get remove -f --purge vlc vlc-data vlc-nox vlc-plugin-notify vlc-plugin-pulse

And then these:

sudo apt-get install -f vlc vlc-data vlc-nox vlc-plugin-notify vlc-plugin-pulse

Apparently everything gets back to normal. Even the icons got back.
Now I finally am able to run vlc on the terminal and get some response. Unfortunatey I still am not able to make it run properly, VLC does not open by any chance. This pops up:

VLC media player 2.0.5 Twoflower (revision 2.0.5-0-g1661b7d) 



The remote control interface was started. Type 'help' for help.

However, not a single window opens.
