My workaround was to edit /var/lib/dpkg/info/mysql-server-5.7.triggers and to change the invoke() function:
invoke() { if pathfind invoke-rc.d; then invoke-rc.d mysql $1 systemctl $1 mysql else /etc/init.d/mysql $1 fi } I'm running mysql in an LXC container. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573279 Title: package mysql-server-5.7 5.7.11-0ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 during release upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1573279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
