Am I trying to connect to a TLS-enabled daemon without TLS?

Question

I\'m trying to learn about Docker, but I keep getting cryptic (to me) error messages.

Possibly the simplest example of this is trying to print the version of Docker

Answer 1

Everything that you need to run Docker on Linux Ubuntu/Mint:

sudo apt-get -y install lxc
sudo gpasswd -a ${USER} docker
newgrp docker
sudo service docker restart

Optionally, you may need to install two additional dependencies if the above doesn't work:

sudo apt-get -y install apparmor cgroup-lite
sudo service docker restart
