MariaDB Error 1558: Incompatible System Tables After Upgrade
Description
This error indicates that the internal system tables in the `mysql` database have an incompatible schema with the currently running MariaDB server version. It typically occurs after a MariaDB server upgrade when the system tables from a previous version have not been updated to match the new server's requirements, leading to a mismatch in column counts for critical tables.
Error Message
Column count of mysql.%s is wrong. Expected %d, found %d. Created with MariaDB %d, now running %d. Please use mysql_upgrade to fix this error.
Known Causes
3 known causesIncomplete Upgrade Process
After upgrading MariaDB, the `mysql_upgrade` utility was not executed, leaving the system tables in an old format incompatible with the new server version.
Manual System Table Modification
System tables within the `mysql` database were manually altered or corrupted, leading to an incorrect schema that the server does not expect.
Downgrading MariaDB Server
Attempting to run a newer MariaDB data directory with an older MariaDB server version can cause schema incompatibilities if the system tables were already upgraded.
