I did the following commands:
sudo rename 's/\.list$/.list.disable/' /etc/apt/sources.list.d/*.list
sudo apt-get update
sudo aptitude -f install libgl1-mesa-dri:i386=9.2.1-1ubuntu3 libgl1-mesa-glx:i386=9.2.1-1ubuntu3`
Now everytime I try sudo apt-get update
I get the following:
N: Ignoring file 'linrunner-tlp-trusty.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'fossfreedom-rhythmbox-plugins-trusty.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'atareao-atareao-trusty.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'steam.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'webupd8team-sublime-text-2-trusty.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
My questions are: What exactly have I done to my system and how can I revert it?
