Cannot load from mysql.proc. The table is probably corrupted

Following from my dependency hell problems the other day my new version of MySQL/MariaDB seems to have all its stored procedures corrupted, displaying the following message when any of them are executed:

Cannot load from mysql.proc. The table is probably corrupted

also "your MariaDB server version for the right syntax to use near 'mysql_upgrade' at line 1"

how to fix it ? run below command to fix it.

> mysql_upgrade  -uroot -p

Problem solved.
