Installing container
Please wait until the server is ready. This page will redirect you to the login once done.

Log:

:rotating_light: Could not find a valid Nextcloud source in /var/www/html
Double check your REPO_PATH_SERVER and STABLE_ROOT_PATH environment variables in .env

This is actually something I have done many times. So I do not know where this one is coming from. I have installed this several times but have never encountered this. I do not know what to do, please somebody help me

Sounds like you’re using the one here:
GitHub - juliushaertl/nextcloud-docker-dev: Nextcloud development environment using docker-compose

Post your Docker run command line or Compose and we may be able to help.

Have you checked out the NC server git repository to workspace/server (or workspace/stableXX respective) before starting the containers?

You might want to share the .env file as well as the docker-compose.yml is quite generic and lengthy.
