Software Center, Update Manager stopped working
up vote 0 down vote favorite

My software center stopped working. I can open it, but any search I do (or any category I select) gives me a blank screen with the revolving circle without ever presenting any results.

I launched the update manager hoping that an update might resolve the problem and I got an error message. The error message ( could not initialize the package information) made me think that the two problems might be related.

Error Message

How can I debug this and update my OS?

Looks like that file might have been corrupted. It gets downloaded during a apt-get update, so open a terminal and do this

sudo rm /var/lib/apt/lists/archive.canonical.com_ubuntu_dists_natty_partner_binary-amd64_Packages
sudo apt-get update

Then open up update manager

Yup. It's also safe to go ahead and delete everything in /var/lib/apt/lists. They'll all get recreated with the apt-get update. – Mark Russell Jul 10 at 16:16

Thanks, that worked :-) – Calixte Jul 10 at 16:49
