Tried all the fixes here to no avail. Ubuntu Software Center opens fine, but when I attempt to click the
Install button for any of the programs, no authentication pops up (as it does on my other 12.04 install) and nothing downloads. It flashes installing and then stops.
Edit menu I cannot alter the checkmarks on tabs such as
Ubuntu Software and
Downloadable from the Internet. It lets me click the check mark and turns it right back off again.
apt-get from Terminal works fine for the same programs.
It seems like my permissions were locked somehow, but I don't know what directory it wants to download into and don't know how to fix it. Do I need to run Software Center as a super user?
This was an upgrade from 11.10 if that matters.
