Compose: ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

[WIttyJudge]

I tried anything in that issue.

witty@witty:~/Desktop/sites/code/finance-api$ sudo docker-compose build
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

Some information:

sudo docker info

witty@witty:~/Desktop/sites/code/finance-api$ sudo docker info
Client:
 Debug Mode: false

Server:
ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
errors pretty printing info

Hi, @WIttyJudge try sudo usermod -aG docker your-user. It works for me.
