Thank you for taking the time to file a bug report. The error says you're attempting to *downgrade* mysql-5.7, and to confirm you need to remove a file and try again:
If are sure you want to downgrade to 5.7, remove the file /var/lib/mysql/debian-*.flag and try installing again. Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'. However, if you believe that this is really a bug in Ubuntu, then we would be grateful if you would provide a more complete description of the problem with steps to reproduce, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to 'New'. For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** Summary changed: - package mysql-server-5.7 (not installed) failed to install/upgrade: subprocess new pre-installation script returned error exit status 1 + package mysql-server-5.7 failed to downgrade ** Changed in: mysql-5.7 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853967 Title: package mysql-server-5.7 failed to downgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1853967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
