I have recently uninstalled
ubuntu-web-browser from my ubuntu 14.04 using synaptic package manager as I don't use it. Now I can't start vlc media player nor play any file using vlc. It sort of opens and then immediately closes down automatically. I get this when I try opening
vlc in the terminal:
VLC media player 2.1.4 Rincewind (revision 2.1.4-0-g2a072be) [0x8f6d910] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. [0x8ff7368] skins2 interface error: no suitable dialogs provider found (hint: compile the qt4 plugin, and make sure it is loaded properly) [0x8ff7368] skins2 interface error: cannot instantiate qt4 dialogs provider [0x8ff7368] [cli] lua interface: Listening on host "*console". VLC media player 2.1.4 Rincewind Command Line Interface initialized. Type `help' for help.
I have installed ubuntu anew twice because of this vlc problem. But only this time I realised it was due to uninstallation of ubuntu-web-browser that vlc stops working. I know this because I tested that vlc runs before I uninstalled the mines and the other games and then ubuntu browser. But after uninstalling these, vlc won't start. So I suspect uninstalling these is the cause.
Now my question is if vlc depended on some packages that were uninstalled due to uninstallation of some other stuff, then why would those packages be removed even when vlc had dependency on them? (am I wrong, or missing something?) How are the dependencies maintained during uninstallation? Also, how can I get vlc running without installing ubuntu again?
New absurd observation:
I uninstalled the games in ubuntu using the following command found here
sudo apt-get remove --purge gnome-mahjongg gnomine gnome-sudoku aisleriot
and same problem occurs !!! Vlc stopped working, and same error message in terminal! Anyone knows what the problem is, and how to solve it?
Yet another absurd observation
This time I uninstalled the games using
apt-get remove, but vlc keeps working. Then
unity-tweak-tool gives error message while starting. This was solved by installing
unity-webapps-service as said here. Then vlc stops working, giving that message again!
