[debian-mysql] Bug#993219: Bug#993219: mariadb-server-core: Akonadi database - mysql_upgrade fails always with "FATAL ERROR: Can't execute 'mysqlcheck'"

[Ulrich Beckmann]

Otto,

I don't have the crashed database available. What I say is, that I have 3 
working Akonadi databases, one in a fresh Bullseye install.

In any case the call of mysql_upgrade fails.
bequimao at bullseye-kde-vm:~$ mysql_upgrade --defaults-file=/home/
bequimao/.local/share/akonadi/mysql.conf --socket=/run/user/1000/akonadi/
mysql.socket -v
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
FATAL ERROR: Can't execute 'mysqlcheck'
bequimao at bullseye-kde-vm:~$ 

So any future database migration would fail. A database migration in the past 
might have failed, see mysql.err in the attachments to message #17.
