Hi Joe, I'm very sorry for the trouble you've been having with this bug. There is actually a workaround in comment #5 that will fix this problem for you. I've added the workaround to the original bug description, and will include it here so as well so that it's not buried in the many comments. It involves typing a single command into the terminal, and once this is done Software Center should work as expected from that point on. Please give this a try and it should take care of the problem for you.
WORKAROUND: This bug can happen if the directory ~/.cache/software-center is created with root ownership somehow (see bug 652151 for some possible scenarios for how this might happen). The fix is to set the ownership if this directory back to your user account. You can do this by typing the following into a terminal window (be sure to substitute your own username as noted below): sudo chown -R yourusername:yourusername ~/.cache/software-center After this, Software Center should launch correctly. ** Description changed: Binary package hint: software-center - live ubuntu from USB + WORKAROUND: + + This bug can happen if the directory ~/.cache/software-center is created + with root ownership somehow (see bug 652151 for some possible scenarios + for how this might happen). + + The fix is to set the ownership if this directory back to your user + account.
