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@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@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. Ulrich
