mutlipass - ubuntu vm's from canonical

snap install multipass --classic (apparently this option is required and allows the snap to violate it's sandbox??)

https://multipass.run/


launch an instance:
* `multipass launch --name ubuntu-lts`
* `multipass stop ubuntu-lts`
* `multipass delete ubuntu-lts-custom`
* `multipass purge`
* `multipass find`

you have to `sudo multipass shell` to get a sudo-able shell
