How to remove docker from Windows subsystem?

I tried to install Docker CE for Ubuntu in the Windows Subsystem for Linux, and I had trouble getting it to work properly. I discovered that perhaps Docker doesn’t work in WSL, so now I’m trying to remove it.

I’ve successfully removed GPG keys and Docker repo from apt, but I’m getting the following error when I try to remove the Docker package:

  ~ sudo apt-get --purge remove docker-ce Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED:   docker-ce* 0 upgraded, 0 newly installed, 1 to remove and 4 not upgraded. 1 not fully installed or removed.
