Title:
package mysql-server-5.7 (not installed) failed to install/upgrade:
subprocess new
Mariadb-10.0 was installed on the system.
I purged all mariadb packages.
Then when I try to install mysql - it should not error out without showing the
decision for user action.
If /var/lib/mysql/debian-10.0 file needs to be removed, the installer
should actually ask it.
** Changed in:
It looks like this is intentional:
Preparing to unpack .../mysql-server-5.7_5.7.12-0ubuntu1_amd64.deb ...
Aborting downgrade from (at least) 10.0 to 5.7.
If are sure you want to downgrade to 5.7, remove the file
/var/lib/mysql/debian-*.flag and try installing again.
