This appears to hit a corner case with respect to multiarch, in that changing a package from Multi-Arch: same / Arch: any to Multi-Arch: no / Arch: all is not handled cleanly on upgrade.
As libkadm5srv-mit8 appears to now be a transitional package, the correct solution here would appear to be to make it Arch: any / Multi- Arch: same again. ** Changed in: krb5 (Ubuntu) Status: New => Triaged ** Changed in: krb5 (Ubuntu) Importance: Undecided => High ** Also affects: krb5 (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: krb5 (Ubuntu) Status: Triaged => Invalid ** Changed in: krb5 (Ubuntu Trusty) Status: New => Triaged ** Changed in: krb5 (Ubuntu Trusty) Importance: Undecided => High ** Changed in: krb5 (Ubuntu Trusty) Assignee: (unassigned) => Michael Vogt (mvo) ** Changed in: krb5 (Ubuntu Trusty) Milestone: None => ubuntu-14.04.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334052 Title: package libkadm5srv-mit8 1.10.1+dfsg-6.1ubuntu1 failed to install/upgrade: libkadm5srv-mit8:all 1.12+dfsg-2ubuntu4 (Multi-Arch: no) kann nicht zusammen mit libkadm5srv-mit8 installiert werden, welches mehrere installierte Instanzen hat To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1334052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
