Install snapd on Debian
On Debian snapd is available as part of the testing (currently ‘stretch’) and unstable (‘sid’) versions. It is currently not available in any stable version but will be soon.
Note: Rasbian is currently not supported due to missing features in the kernel shipped.
Generally you can install snapd on a Debian distribution via:
$ sudo apt install snapd
Afterwards everything is setup to get you started with snaps.
