It's worse than I thought. I finally gave up and closed down Ubuntu Software Center, or at least I thought I did, but every minute or so it reappeared, obscuring the windows for the foreground apps I was working in. I did some more digging, and found this using ps:
6131 ? Sl 0:00 /usr/bin/python /usr/share/software-center/submit_usefulness_gtk3.py --review-id 85959 --is-useful 1 --parent-xid --datadir /usr/share/software-center/ 6142 ? Sl 0:00 /usr/bin/python /usr/share/software-center/submit_usefulness_gtk3.py --review-id 89278 --is-useful 1 --parent-xid --datadir /usr/share/software-center/ So apparently the script to submit the feedback is hanging and making a zombie out of USC (not a zombie in the sense we use that term in the UNIX world, but the image for the USC window isn't going away until I kill those two processes, so that's what I'm going to do. Since I can't re-open this ticket, am I going to have to file a new bug report? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/790450 Title: 'Submitting now...' spinner runs forever on usefulness submit fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/790450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
