A manual installation of libpam0g appears to fix the problem. I experienced the same problem updating a gutsy -> hardy server this evening. Updates were applied at 18:30+10 Saturday 12th April. Upgrade to hardy was then done at 19:00+10. This failed and investigation followed. The upgrade appears to be running correctly after completing the workaround below.
To work around this issue; After the initial failure $ sudo apt-get install libpam0g $ sudo do-release-upgrade -d Upgrade should continue as expected, it did for me. -- Upgrade to hardy beta fails https://bugs.launchpad.net/bugs/215532 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
