Thanks for the added information and sorry for the trouble. @xfx: the while loop you see there shouldn't cause the behavior described here. If that hangs forever it will at least update the GUI. But it was indicated that the update-manager window is not redrawn.
@James: do-release-upgrade behaves slightly differently than update- manager, see http://wiki.ubuntu.com/UpdateManagerFaq I tested a lot of different scenarios but I was not able to reporduce the problem here. If someone still can reproduce the hang, please contact me, I would like to provide you with a debug build of update- manager. -- "distribution upgrade" hangs during update to hardy https://bugs.launchpad.net/bugs/186465 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
