Errors at end of doing a dist-upgrade on MD

Did a dist-upgrade on my core which went fine it would seem (didn't take very long). Then did it on an MD, which took a good few hours, but it ended with the errors below:

Tried to:

mysql> GRANT ALL PRIVILEGES ON pluto_main.* TO root@192.168.80.4;
mysql> FLUSH PRIVILEGES

...on the core, but got the same error again on the MD when re-attempting the dist-upgrade.
