What program did you use to do the upgrade ? (Reassigning to apt in the mean time)
The ordering of the upgrade of the perl package was really bad... it unpacked first perl-modules and perl almost together but perl-base much later, leaving perl completely broken during a large window and resulting in many other package installation failing. ** Package changed: dpkg (Ubuntu) => apt (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/875830 Title: package python-twisted-names 10.1.0-1build2 failed to install/upgrade: ErrorMessage: package python-twisted-names is already installed and configured To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/875830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
