The issue you are facing:
Is this the first time you’ve seen this error? (Y/N): Y
I am using docker-compose for my nextcloud setup. I forgot to update my nextcloud for a while and wanted to do it. I did use these commands:
docker-compose pull docker-compose up -d
My yml file looks like this:
version: '3' services: db: image: mariadb command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW restart: always volumes: - db:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=hiddenpw env_file: - db.env container_name: new_nextcloud_db app: image: nextcloud:fpm-alpine restart: always volumes: - nextcloud:/var/www/html environment: - MYSQL_HOST=db env_file: - db.env depends_on: - db container_name: new_nextcloud_app web: build: ./web restart: always volumes: - nextcloud:/var/www/html:ro environment: - VIRTUAL_HOST=hiddendomain - LETSENCRYPT_HOST=hiddenhost - LETSENCRYPT_EMAIL=hiddenemail depends_on: - app networks: - proxy-tier - default container_name: new_nextcloud_web
Since then, my clients cannot connect and I get also this message:
Internal Server Error The server encountered an internal error and was unable to complete your request. Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report. More details can be found in the server log.
Sadly I fail to know where the server log is saved. But I get also another message via ssh:
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 Set log level to debug Exception: Updates between multiple major versions and downgrades are unsupported. Update failed Maintenance mode is kept active
I am sure that before my update I didn’t use nextcloud 17 or 16. I think it was version 12.
So I tried downgrading but I failed.
My questions are:
Can I downgrade and progressively upgrade until I reach version 18?
Is there another solution?
Since I know that error logs are key for problem solving, can anybody give me an advice where to find my errorlogs when using docker compose? Than I could publish them here.
