Windows Subsystem for Linux (WSL) Docker: error storing credentials – err: exit status 1, out: Cannot autolaunch D-Bus without X11 $DISPLAY

Recently at work, when copying an application from our internal Docker Registry to Azure, I ran into the following error in my WSL Ubuntu installation.

Login at docker..com
Username: 
Password:
Error saving credentials: error storing credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`
ERROR: source registry login failed

The easiest fix I found was to install the gnupg2 and pass packages.

sudo apt install gnupg2 pass 

One important thing to note regarding security: the output mentioned storing the credentials in plain text as a result somewhere in the WSL user’s /home directory. If you are very conscious about where passwords are stored, do not use this solution or remove the password file afterwards. That’s good enough for me at the moment, I just needed to get this to work somehow.
