My docker instance of Nextcloud is set to auto-upgrade and today it has gone offline. I use watchtower to keep the images up-to date. I tried running the upgrade command, but it does not look happy with the database:
docker exec --user www-data nextcloud php occ upgrade Nextcloud or one of the apps require upgrade - only a limited number of commands are available You may use your browser or the occ upgrade command to do the upgrade Setting log level to debug Turned on maintenance mode OC\DB\Exceptions\DbalException: Unknown database type enum requested, Doctrine\DBAL\Platforms\MariaDb1027Platform may not support it. Update failed Maintenance mode is kept active Resetting log level
Nextcloud is a docker container running on 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64. and is the latest from the docker hub at the time of writing this.
The database is mariadb, another docker container. A Raspberry pi running VMware ESXi and the photon OS as a guest OS:
4.19.160-3.ph3 #1-photon SMP Thu Dec 10 02:33:38 UTC 2020 aarch64
Version: 10.5.8-MariaDB-1:40.5.8+maria~focal mariadb.org binary distribution
Compiled For: debian-linux-gnu (aarch64)
An extract from config.php file
'dbtype' => 'mysql', 'version' => '188.8.131.52', 'dbname' => 'nextclouddb', 'dbhost' => 'mysql.something.something', 'dbport' => '3306', 'dbtableprefix' => 'oc_',
I can connect to the mysql host and other databases are reachable from their applications (grafana and others).
Any ideas why the upgrade is unhappy?
Any specific log information I can provide to narrow down the problem?
