Also trying to convert the database beforehand fails:
# nextcloud-occ db:convert-type mysql nextcloud localhost nextcloud
What is the database password?
Creating schema in new database
In Connection.php line 85:
Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [1044] Access denied for user 'nextcloud'@'localhost' to database 'nextcloud'
db:convert-type [--port PORT] [--password PASSWORD] [--clear-schema] [--all-apps] [--chunk-size CHUNK-SIZE] [--] <type> <username> <hostname> <database>
# runuser -u nextcloud -- nextcloud-occ db:convert-type --all-apps mysql nextcloud localhost nextcloud
