I've upgraded the mariadb to 10.3 packages on my Debian 10, however something went wrong and I ended in the same issue which is mentioned several times

So in my case you can see mysql_upgrade complains of missing tables although they seem to exist

$ sudo mysql_upgrade -u root --force -pxxxxx

As non-db expert and althought some of the posts mentioned above are old, I followed them trying to solve the problem

  1. Stop mariadb with sudo systemctl stop mariadb
  2. Delete files
    cd /var/lib
    sudo rm mysql/ibdata1
    sudo rm mysql/ib_logfile0
    sudo rm mysql/ib_logfile1
    sudo rm mysql/mysql/innodb_index_stats.ibd
    sudo rm mysql/mysql/innodb_table_stats.ibd
    sudo rm mysql/mysql/gtid_slave_pos.frm
    sudo rm mysql/mysql/gtid_slave_pos.ibd
    sudo rm mysql/mysql/slave_master_info.frm
    sudo rm mysql/mysql/slave_master_info.ibd 
    sudo rm mysql/mysql/slave_worker_info.frm
    sudo rm mysql/mysql/slave_worker_info.ibd
    sudo rm mysql/mysql/slave_relay_log_info.frm
    sudo rm mysql/mysql/slave_relay_log_info.ibd
    
  3. Start mariadb with sudo systemctl start mariadb
  4. Open mysql using mysql -u root -p
  5. Recreate tables for mariadb 10

Drop tables on the system tables that are reporting errors.

mysql_upgrade --force to recreate them.

Avoid ever deleting any MariaDB files except as documented in official manuals (not random people's blogs), and even then under very careful following of the conditions and insturctions provided.
