I have been testing the Trusty to Xenial upgrade path, and can confirm this happens when upgrading to Xenial and mysql 5.7 from a clean install of Trusty with mysql 5.5.
I'm not formally trained in the "Debian way" but from my experience it seems like the "correct" way to resolve this might be to offer to overwrite the existing configuration and then error out when the old configuration with deprecated options is left in-place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1570673 Title: package mysql-server-5.7 5.7.11-0ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1570673/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
