Can't install software from Ubuntu software center
- by Casbar
I've been experimenting with Ubuntu 10.04(64bit) inside a VirtualBox VM. This isn't my first experience with Linux, but I'm still very much a Linux noob.
Whenever I try to install software from the Ubuntu Software Center, the installation gets interrupted and I get a warning that this installation requires untrusted sources. I can install anything I want using apt-get, it's just the gui that doesn't work. I've done research on the issue and taken the following precautions with no result:
under software sources
Allowed Canonical partners
Allowed source code
Changed the download source to main server
I get no errors when running an apt-get update. Can anyone shed some light on the issue?
