I'm trying to download the MATLAB program through the software center on Ubuntu 12.04. The installation has stalled half way through (in the applying changes phase), but I can't cancel it. I've tried restarting the computer, but the download still shows and I can't remove it. It also prevents me from downloading any other programs on software center. What can I do to remove the item from my software center download list?
I tried the solutions posted here and I get another error:
