I am having this issue right now. Before updating, I did: sudo apt-get-update sudo apt-get dist-upgrade
..and then launched Software Updater. However, it seems that the newest version of the software updater didn't install for whatever reason. As the install is running, if I do: $ apt-cache policy ubuntu-release-upgrader-core ubuntu-release-upgrader-core: Installed: 1:15.10.14.4 Candidate: 1:16.04.14 Version table: 1:16.04.14 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main i386 Packages 1:16.04.12 500 500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 500 http://us.archive.ubuntu.com/ubuntu xenial/main i386 Packages *** 1:15.10.14.4 100 100 /var/lib/dpkg/status ..so obviously the software updater somehow escaped getting updated, so I got the version with the bug still. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1560797 Title: apt does not configure Pre-Depends: before depending package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1560797/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
