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

For what it is worth, I tried all the solutions in this question and in this related question and none resolved my issue until I uninstalled and re-installed VirtualBox. This process upgraded the VirtualBox from version 4.2.16 to 4.3.22 (my previous one had been lying unused on the system for a few months).

Then boot2docker and docker worked without any other adjustments.
