vlc установлен, но не включен в систему?

Дорогое сообщество Ubuntu,

Это очень странно для меня. Я добавил ночную сборку ppa для vlc, установил vlc, удалил vlc, а затем удалил ppa. Теперь я застрял:

$ sudo apt-get  install vlc

Reading package lists... Done

Building dependency tree  

Reading state information... Done

vlc is already the newest version.

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

$ which vlc

$ /usr/bin/vlc

bash: /usr/bin/vlc: No such file or directory

$ vlc

The program 'vlc' is currently not installed. You can install it by typing:

sudo apt-get install vlc-nox
