If you get an error such as `unknown shorthand flag: 'd' in -d` or `open <location of your .env file>: permission denied`, you are probably running the wrong Docker version. (This happens, for example, with the docker.io package in Ubuntu 22.04.3 LTS.) You can correct the problem by following the complete [Docker Engine install](https://docs.docker.com/engine/install/) procedure for your distribution, crucially the "Uninstall old versions" and "Install using the apt/rpm repository" sections. These replace the distro's Docker packages with Docker's official ones.
Note that the correct command really is `docker compose`, not `docker-compose`. If you try the latter on vanilla Ubuntu 22.04, it will fail in a different way:
If you get an error `can't set healthcheck.start_interval as feature require Docker Engine v25 or later`, it helps to comment out the line for `start_interval` in the `database` section of the `docker-compose.yml` file.
