The DpkgHistoryLog.txt shows you installed MySQL Server 5.7, and then MariaDB Server 10.1. This migration path is not supported. From Oracle MySQL 5.7 you need to upgrade to MariaDB 10.2 or newer.
To solve this situation, you need to apt-get purge mysql-* mariadb-*, possibly by hand also run rm -rf /etc/mysql /var/lib/mysql and then try installing again mariadb-server only. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1683229 Title: package mariadb-server-10.1 failed to install since mysql-server-5.7 isn't purged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mariadb-10.1/+bug/1683229/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
