We had the same problem while upgrading from edgy to feisty to gutsy. In gutsy dist-upgrade we got the segfaults.
Our solution in quick notes from memory: * We left out what was mentioned in the second post. * Only installed libc6-xen with aptitude (accepted the proposed downgrade solution). Segfaults were gone now, and we were able to configure the list of unconfigured packages! After that we still had problems with a newer version of libc (...ubuntu10). Then we did: * add multiverse to /etc/apt/sources.lst * aptitude install ubuntu-xen-server Getting much further now.. but still config probs * aptitude remove libc6-i686 ubuntu-minimal sounded like a "reasonable" solution. and indeed now we're able to successfully finish an aptitude upgrade run. but: The following packages have been automatically kept back: libc6 libc6-dev guess that we have to wait for the updated libc6-xen version to meet these dependencies. -- update-rc.d segmentation fault on upgrade from clean feisty to gutsy https://bugs.launchpad.net/bugs/152664 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
