After upgrade from 14.04 to 16.04, KMail won't give me access to my data.
The problem with the deprecated innodb_additional_mempool variable has already been fixed.
Now the problem is that the Akonadi server won't start, and the reason appears to be that my database was created with MySQL 5.5 or so, and now 16.04 runs with 5.7 or so.
There's a mysql.err file with messages like
2017-01-25T18:19:57.920135Z 0 [ERROR] Column count of performance_schema.events_waits_current is wrong. Expected 19, found 16. Created with MySQL 50538, now running 50717. Please use mysql_upgrade to fix this error.
Perfectly willing to try this, but no idea where to find mysql_upgrade, let alone how to start it, let alone how to use it.
Can anyone help me out with this ?
