Thanks for the review Robie, I have tested the package on the proposed pocket by using this script:
------------ #!/bin/sh set -x series=trusty name=$series-upgrade multipass delete $name multipass purge multipass launch $series --name $name multipass exec $name -- sudo sh -c "cat <<EOF >/etc/apt/sources.list.d/ubuntu-trusty-proposed.list # Enable Ubuntu proposed archive deb http://archive.ubuntu.com/ubuntu/ trusty-proposed restricted main multiverse universe EOF" multipass exec $name -- sudo apt-get update multipass exec $name -- sudo apt-get upgrade -y multipass exec $name -- sudo apt-get dist-upgrade -y multipass exec $name -- do-release-upgrade set +x ------------- Using it, I can confirm that the unattended-upgrades prompt no longer appears. If there is more testing that should be performed regarding this package, please let me know and I can perform them as well -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915547 Title: Users are prompted by ucf on upgrade from Trusty to Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1915547/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
