Public bug reported: I've got a number of automatic upgrade tests running daily, which all use the noninteractive frontend. As of a few days ago, the trusty->xenial amd64 desktop qemu uefi upgrade testing is having problems:

I can get more output if necessary. This problem doesn't appear to occur on other trusty->xenial amd64 desktop qemu installs, so I'm uncertain if it's related to a package installed to support the UEFI boot or some other difference between that and the other images. ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604160 Title: Unicode decode error in noninteractive frontend on t->x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1604160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
