The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 30.0.5.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 22.04
  • Web server and version (e.g, Apache 2.4.25):
    • Not sure but the latest docker image
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • nginx proxy manager
  • PHP version (e.g, 8.3):
    • PHP 8.1.2-1ubuntu2.20
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • Today
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • Docker Portainer Stack (docker.io library nextcloud:latest)
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • Cloudflare

Summary of the issue I am facing:

12 hours ago I moved the volume folder of nextcloud_db container from the default docker volume folder (/var/lib/docker/volumes/[nextcloud_db_id]/_data)
to my custom location (/root/nextcloud_data/db_volume)

for safety issue

I first stopped the stack using Portainer, then used rsync -av to copy the db_volume， then added the below command in docker-compose file and deployed in Portainer again.

volumes:
  - "/root/nextcloud_data/db_volume:/var/lib/mysql"

However, after deployment, I am not able to access my admin account after logging in.

for example: [domain]/index.php/apps/deck/ shows
“The page could not be found on the server or you may not be allowed to view it.”

and : [domain]/index.php/apps/dashboard/ shows
“Internal Server Error. The server was unable to complete your request.”.

However, the two other guest accounts are working as usual.

Steps to replicate it:

  1. Create a Portainer stack with nextcloud app container and MariaDB container together, not set up volume parameter for MariaDB
  2. After deployment, create an admin account and a guest account, then stop the stack, rsync the MariaDB volume folder from /var/lib/docker/volumes to any folder under /root folder
  3. Add the new volume path in the Portainer stack file for the MariaDB container, and start the stack again, you will see that the admin account is not able to access webpages anymore while the guest account works fine.

Log entries

when starting the stack after movement the docker log will show “New Nextcloud Instance” and tried to use occ maintenance:install but failed many times.

I have tried the following methods but not working:

  1. deploy using merely the db_volume and /var/www/html/data(to general new config file), it asked me to create another admin account, and yet still not able to access after logging in the original admin account.
  2. try
    • maintenance:repair
    • maintenance:data-fingerprint
    • occ files:scan-app-data
    • maintenance:mimetype:update-db
      and none of these works
  3. try to repair the MariaDB manually but no errors or clues.

I managed to solve it myself!

Proud of me!

It turns out that sudo -u www-data php occ app:disable deck helps me get rid of the default welcome page after login, and strangely

all the manually installed apps were gone!

and I have to recover them one by one.

This must be a huge bug!

Thankfully all the app-related data are all saved and I can keep my work progress tracked again.

If someone can kindly reply to me and let me know about what the hack I have been through and figure out the reason, I will be so grateful!

Thank you! :innocent:

Thank you for your help!

And as far as I know, the compose file before has a typo which cause the nextcloud app to set-up another mariadb named “nextcloud” instead of “nextcloud_db”, but it is not a very big problem.

And if you find anything that can be improved, please let me know for sure!
For example, which address should I use for overwriting ?
