Actually, I'm not convinced that update-manager is the front end in use here. If we look at the JournalErrors.txt file attached to this bug we can see the following:
dic 02 09:33:40 hostname org.debian.apt[871]: 09:33:40 AptDaemon [INFO]: Initializing daemon dic 02 09:33:40 hostname org.debian.apt[871]: /usr/lib/python3/dist-packages/aptdaemon/worker/pkworker.py:35: PyGIWarning: PackageKitGlib was imported without specifying a version first. Use gi.require_version('PackageKitGlib', '1.0') before import to ensure that the right version gets loaded. dic 02 09:33:40 hostname org.debian.apt[871]: from gi.repository import PackageKitGlib as pk My testing indicates that these errors only appear in the journal when gnome-software is being used and not update-manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646739 Title: "Use of uninitialized value" in debconf via update-manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debconf/+bug/1646739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
