I can confirm this problem. I am using a Ubuntu 11.04 system with kernel 2.6.39. I have to reinstall system because I accidentally removed some system directory in the evening.
I chosed 'Upgrade 11.04 to 11.04' on the screen, its fine. And I was surfing around with Firefox until met the same problem. Here is my screen shot. At this time, when I found this defect record and finish my comment, it is still pending on. BTW. I don't remember whether it has happened when I upgrade from 10.10 to 11.04 last month. ** Attachment added: "screen shot" https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/747579/+attachment/2162337/+files/Screenshot.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/747579 Title: Ubiquity gets stuck at restoring previous packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/747579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
