Looks like you have a large number of Personal Package Archives (PPAs) that have not had their contents rebuilt for Xenial. The supported upgrade tools remove PPAs before performing upgrades for this reason. You should contact the PPA owners to obtain support.
Since this has nothing to do with Unity I'm marking it as invalid. ** Changed in: unity (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547600 Title: Xenial Terminal after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1547600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
