Hi, I'm trying to upgrade a MariaDB 10.2 server to 10.4.6 on FreeBSD. When running the mysql_update command, it dies with: $ mysql_upgrade Phase 1/7: Checking and upgrading mysql database Processing databases mysql mysql.column_stats OK mysql.columns_priv OK mysql.db OK mysql.event OK mysql.func OK mysql.global_priv OK mysql.gtid_slave_pos OK mysql.help_category OK mysql.help_keyword OK mysql.help_relation OK mysql.help_topic OK mysql.index_stats OK mysql.innodb_index_stats OK mysql.innodb_table_stats OK mysql.plugin OK mysql.proc OK mysql.procs_priv OK mysql.proxies_priv OK mysql.roles_mapping OK mysql.servers OK mysql.table_stats OK mysql.tables_priv OK mysql.time_zone OK mysql.time_zone_leap_second OK mysql.time_zone_name OK mysql.time_zone_transition OK mysql.time_zone_transition_type OK mysql.transaction_registry OK Phase 2/7: Installing used storage engines... Skipped Phase 3/7: Fixing views mysql.user OK Phase 4/7: Running 'mysql_fix_privilege_tables' ERROR 1071 (42000) at line 437: Specified key was too long; max key length is 1000 bytes FATAL ERROR: Upgrade failed Adding verbose option does not give more hints, and the failing SQL statement doesn't seem to be logged with full query logging turned on. How do I debug this? I can't even see which table or column it's complaining about. I don't remember fiddling with collation or character sets on system tables. Kind regards, Erik
