@natacha-beck would you mind bumping the [Ubuntu version in the Dockerfile](https://github.com/BFL-lab/Mfannot/blob/0990c858a5a90a86eb3efc372460686e67039aac/Dockerfile#L1) to v20.04 or greater? The current version does not support attaching [VSCode to the container](https://code.visualstudio.com/docs/remote/faq#_can-i-run-vs-code-server-on-older-linux-distributions).
