mysqld: Can not perform keyring migration

Question

Trying to install a mysql8.0 on (not yet supported) debian 10 (aka "Buster") system that formerly held mysql5.5. Installation ends with:

mysqld: Can not perform keyring migration : Invalid --keyring-migration-source option. [System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.11) starting as process [ERROR] [MY-011084] [Server] Keyring migration failed.

I have no need of any encryption. Also I think I had not used a "keyring" before. My question is: what do I have to do to use mysql? Is it maybe possible to skip the keyring migration?

Answer 1

Oh, the server did start, regardless of the ERROR message. See also https://dba.stackexchange.com/questions/189341/can-an-encrypted-mysql-restart-without-the-keyring-file-on-the-box:

Yes, mysql will start, but you will receive an error if you try to access the encrypted table.
