@john-light I'll admit I haven't used this gist in a couple of years, so I'm not sure just by looking at the error log. I'd try experimenting with different deb versions depending on your OS (e.g. you may be using a more recent version of ubuntu). According to this, there's also eoan and bionic available. You could try uninstalling and using one of those in the sudo add-apt-repository step.

@dweldon thanks again! I am using Mint 18.3 (based on xenial) which is how I found this gist. I think I found some clues about the problem, seems to be a networking error. I will continue investigating.

Thank you this worked for me

2020 Still works perfect. Thank you so much!

If someone has an error like Couldn't connect to Docker daemon at http+docker://localhost - is it running?

try
sudo chown $USER /var/run/docker.sock
