Just found the root cause. I leave mysql service disabled (using it only for some testing).

So 'invoke-rc.d mysql start' is just a no-op in that case and since post-install script assume that the service is enabled and running upon start, it fail all time it require mysqld running!

No more mysql_upgrade error 11 with mysql.service correctly enabled!
