phpmyadmin configuration script fails to install db

[Vertago1]

On upgrade to xenial the phpmyadmin configure script failed to upgrade the phpmyadmin database.

I then tried:
1) purging phpmyadmin
2) deleting the phpmyadmin database from mysql
3) reinstalling phpmyadmin

I tried several of the configuration options but was never given the option to enter the mysql admin password after entering the username so the configure script failed every time.

I encountered the same issue. It appears the problem is that the overall Xenial upgrade process attempts to upgrade MySQL and PHPMyAdmin simultaneously. Since MySQL is down while being upgraded, it is not available to process PHPMyAdmin's upgrade script.

I had to reinstall PHPMyAdmin at the end of the upgrade process since I could not find a way to reprocess this database upgrade manually...
