    yeah usually how i do it :)

    1st error seems MariaDB 10.2.2 doesn't like one innodb variable = innodb_buffer_pool_populate so need to remove it from [mariadb-10.2] group in /etc/my.cnf :)

    Ok, that we will do manually before upgrading?

    I have that allredy in my.cnf
    So I should not do anything else when I am going to upgrade?

    Code:
    # innodb settings
    innodb_large_prefix=1
    innodb_file_format = Barracuda

    no need, the centmin.sh menu option 11 submenu option 6 when time comes will take care of it all automatically :D

    though you wouldn't want to downgrade to older MariaDB versions with those settings removed so the warning might remain if you have them.

    ah i see why this isn't supported it's an InnoDB XtraDB Percona engine variable, but initial MariaDB 10.2.2 is merged against Oracle MySQL 5.7 InnoDB engine not XtraDB InnoDB. Guess need to wait for the merge of Percona 5.7 XtraDB InnoDB engine.
    had a similar issue with some variables in early MariaDB 10 alphas as well before they merged in support for InnoDB XtraDB from Percona XtraDB.

    can confirm when you check the innodb engine version for MariaDB 10.2.2
