I got it fixed manually. What I did was: mv /etc/mysql/my.cnf.migrated /etc/mysql/conf.d/custom.cnf cd /etc/alternatives rm my.cnf ln -s /etc/mysql/my.cnf.fallback my.cnf
As dpkg --configure -a still threw errors in the manner of 2016-10-25T09:06:10.251866Z 0 [ERROR] unknown variable 'log=/var/log/mysql.log' 2016-10-25T09:07:29.715102Z 0 [ERROR] unknown variable 'thread_concurrency=8' 2016-10-25T09:07:53.726055Z 0 [ERROR] unknown variable 'innodb_use_sys_malloc=0' I removed the corresponding lines from my custom configuration in /etc/mysql/conf.d/custom.cnf After that, dpkg --configure -a was running without errors and thereby successfully converted the tablespaces to their new binary representation dpkg --configure -a mysql-server-5.7 (5.7.15-0ubuntu0.16.04.1) wird eingerichtet ...

After that, MySQL is up and running again. In the end I assume that the original error was just that the three lines had to be removed from /etc/mysql/my.cnf.migrated. That would have allowed the ubuntu major release update to run through smoothly and without manual intervention. An improvement would have been to just ignore these lines, even if they exist (with the potential of severe damage in other cases, of course). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1636328 Title: package mysql-hostname-5.7 5.7.15-0ubuntu0.16.04.1 failed to install/upgrade: Unterprozess installiertes post-installation-Skript gab den Fehlerwert 1 zurück To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1636328/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
