Well this was annoying. I installed MariaDB 10.1 to find out that it was not compatible with Sonarqube 5.6.6. I purged MariaDB. MySql 5.7 failed to install.
My resolution: Delete all recent files in VAR. Uninstall the failed Mysql. Install Mysql again. Now it succeeded. good luck, Erik -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1490071 Title: MySQL 5.6 refuses to install on systems that have had MariaDB 10.0 installed, preventing users from reverting to MySQL without manual intervention (aka mysql flag file system needs a redesign) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1490071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
