Troubleshooting

Got an issue? Check if listed here.

When downloading, I get ERROR: cannot verify files.skills17.ch's certificate

Issue:

You are likely behind a corporate or school proxy. On corporate or school computers, this is often the case. If you are in a VPN, you might also be affected.

Solution:

We recommend to use a private computer, or turn off the VPN or Proxy.

Hint:

The proxy config is usually in the file ~/.docker/config. You might have to remove the proxy settings from there.

See Docker documentation for more information.

Container Fails to Start

Issue:

One or more containers fail to start when running docker compose up.

Steps:

  • Verify that necessary ports are not already in use.
  • Check general network issues.
  • Check you have enough memory available in Docker settings and on your host.
  • Check you have enough disk space available in Docker settings and on your host.
  • Check container logs with docker compose logs [service_name] to identify specific errors. Try to understand the error message and resolve the issue.

I'm getting an EPERM error when running node setup.js and I'm on Windows

Issue:

You are likely running a command that requires elevated permissions.

Solution:

Make sure you enabled Developer Mode.

This is required to run Node.js and PHP commands. Otherwise, you might encounter EPERM errors.

I'm getting a Permission denied error when downloading/decrypting the tasks, and I'm on Linux/macOS

Issue:

The user and group of your host and Docker container probably mismatch. Therefore, the Docker container user doesn't have the permission to write to your competitions/ directory.

Solution:

Get your user and group ID by running id in your terminal. You need to let Docker know about these IDs by adding them to the docker-compose.yaml file at the competitions-manager level. Replace 1000:1000 with your UID and GID respectively.

        ...
        volumes:
            - ./competitions:/app/data/
        user: "1000:1000"

I'm getting exec /docker-entrypoint.sh: exec format error when running npm start

Issue:

You are likely trying to run the Docker container on an incompatible architecture.

Solution:

Make sure you are running the Docker container on a compatible architecture. Required images are available for both amd64 and arm64 architectures, hence this is not the original of the problem.

Try re-installing Docker and make sure you are using the correct version for your CPU architecture.
