Error executing sourced init when docker is installed using snap

This is the error:

Got the same error, but installing docker-compose by doing as instructed solved it for me:

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

After spending a very short time with this, I don't think it's worth to do anything on our side.
I tried to run sourced as root, and the same error happened. Running it with SOURCED_DIR outside of $HOME fails with a different error.

The Docker snap package is not maintained by docker, and on my machine it installs outdated versions of docker and docker-compose.

$ docker-compose -v
docker-compose version 1.22.0, build unknown
$ docker -v
Docker version 18.06.1-ce, build e68fc7a

I'll add a warning in the docs for this.

Totally agree
