this time it's docker, was: removing wslview from Ubuntu-only computers?

If you'd like to see what apt/apt-get will do without making changes to 
the system, use the "-s" (for simulate) option with the action command

$ sudo apt -s install docker.io

Examine the output and if it looks ok with nothing being installed that 
you don't expect to be installed, then remove the "-s" and run the 
command again.

When you're finished with the project, run this:

$ sudo apt -s autopurge docker.io

Again, examine the output and if nothing is being removed that you don't 
expect to be removed, then run it without the "-s" option.
