CLI snap install method fails under WSL Ubuntu 18.04

Do you want to request a feature or report a bug?

Bug (or at least a gotcha that would be good to document)

What is the current behavior?

1. Enable Windows Subsystem for Linux on latest Windows 10 Pro
2. Install Ubuntu from the Windows Store (the default Ubuntu entry there maps to 18.04)
3. Open a WSL terminal
4. Follow the "Ubuntu 16.04+" instructions on https://devcenter.heroku.com/articles/heroku-cli#download-and-install , which say to sudo snap install --classic heroku

ed@WSL:/c/Users/Ed/src$ sudo snap install --classic heroku
[sudo] password for ed:
error: cannot communicate with server: Post http://localhost/v2/snaps/heroku: dial unix /run/snapd.socket: connect: no such file or directory

What is the expected behavior?

Either:

1. No error and install inside WSL using Snap works
2. Or, documentation says WSL not supported and/or snap install script detects this case and aborts with a user-friendly error

Snap in general appears to fail under Ubuntu.

Also having problems installing Heroku CLI under WSL 2, Ubuntu 20.04.

$ sudo snap install heroku --classic

Interacting with snapd is not yet supported on Windows Subsystem for Linux.
