On a fresh install of Xubuntu 16.04.3, I've ran into a very very surprising issue:
Can't install VLC player:
When trying to install "libgles2-mesa", I see another error:The following information may help to resolve the situation:
The following packages have unmet dependencies:
vlc : Depends: libgles2-mesa (>= 7.8.1) but it is not going to be installed or
libgles2
E: Unable to correct problems, you have held broken packages.
Found a post on askubuntu that suggests it might be related to having installed the proprietary nvidia drivers...The following packages have unmet dependencies:
libgles2-mesa : Depends: libglapi-mesa (= 11.2.0-1ubuntu2) but 17.0.7-0ubuntu0.16.04.1 is to be installed
Hm...
[SOLUTION]
To be continued...
