Hi I have the same problem: When upgrading from web it will hang at 'reading cache'.
When upgrading from the alternate cd it will hang at 'checking package manager'. I tried changing source servers but that did not help. This same issue has also been reported here: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/153984 -- Upgrade to 7.10 hangs at "Modifying the software channels/Checking package manager" https://bugs.launchpad.net/bugs/152296 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
