I recently installed Oneiric, and I am unable to install any software through the software Center, because the Install option is greyed out for everything.

It loads all the software listings alright, but no install button.

I tried apt-get update & apt-get upgrade, enabled everything I saw fit in the software sources, yet no luck.

Installed Synaptic through command line, and it installs packages properly. Since downloaded .deb packages open through the Software Center, I can't install them because install button is greyed out.

Any solutions?

    A workaround for installing .deb files would be to run sudo dpkg -i package.deb. – htorque Oct 15 '11 at 7:35
  • I have the same problem on one computer. The Install button is always grey, even after trying the above the command line and a reboot. The program says there is no network connection even though I post to this web site. – Peter Lawrey Feb 12 '12 at 10:02
  • I have found apt-get install {program} works fine. – Peter Lawrey Feb 12 '12 at 10:07
