>From the log: mysql_upgrade: Got error: 1045: Access denied for user 'debian-sys-maint'@'localhost' (using password: YES) while connecting to the MySQL server
On upgrades the database schema needs to be upgraded as well, for that it will connect to the server and do the upgrades. Usually it uses local access as root or fallback to the user denied here. Both usually work without being an attack vector. Never the less it seems that part of your local configuration locks these ways to access out and thereby the update fails. I'd ask you to modify your configuration in a way to get the upgrade succeeding. If you want you can revert those changes right after the upgrade. If you think those changes are a common setup please outline them here so they can be considered. There currently is a major rework of the upgrade handling and it might be interesting to be considered there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1687700 Title: package mysql-server-5.7 5.7.18-0ubuntu0.16.04.1 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/1687700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
