I already did the apt-get purge, install and update thing but it still freezes when trying to start. This is what I get trying to start in terminal:

cliff@cliff-Aspire-X1301:~$ software-center

I had the same problem. For me removing the cache at ~/.cache/software-center and then opening the Software Center, did the job. Just open your home folder, press ctrl+h to reveal hidden files, open .cache and delete the folder software-center (or, safer, rename it, e.g. to software-centerDeleted). It seems no root permissions are required.

  • Welcome to Ask Ubuntu! Can you expand this with information about how you removed it? For example, did you do it in Nautilus, after pressing Ctrl+H to show the .cache folder? I do think this does count as a separate answer from that one, since you're saying that just removing the cache is sometimes sufficient. (I agree.) As another difference, you're not telling people to do it as root, with sudo. (I agree with you about that, too.) But this could be an even better answer with more details. – Eliah Kagan Jul 26 '14 at 15:21

You can try removing it completely and installing it again:

Uninstall Software Center:

sudo apt-get remove software-center

sudo apt-get autoremove software-center

(IMPORTANT)Remember to remove the cache

~/.cache && rm -r software-center

Reinstall Software Center:

sudo apt-get install software-center

It does look like it need to be updated and this should occur during installation.

    Removing the cache shouldn't have to be done as root, though if people have run the Software Center in weird ways (e.g., sudo software-center--not recommended), it might be necessary. Recursive removals are scary when run as root. But then, they're scary otherwise, too. If someone accidentally puts a space (or presses enter) after the ~ or the first / in rm -r ~/.cache/software-center (with or without sudo), it deletes their entire home folder, including all their documents! (And this does happen.) Therefore, cd ~/.cache && rm -r software-center might be considered preferable. – Eliah Kagan Jul 26 '14 at 15:18
  • Good catch. I have edited my post accordingly. – BiggJJ Jan 28 '15 at 14:30
