The Grafana snap is available to call for testing on beta channel, and please install it with
snap install --beta grafana
Currently, only amd64 version can be built, and seems it has a build issue for armhf version.
The snapcraft.yaml is put into my repo, here’s a link: https://github.com/woodrow-shen/grafana/blob/master/snapcraft.yaml
Also, I create a PR for grafana upstream, refer https://github.com/grafana/grafana/pull/9144
Don’t hesitate to report the issue as I’m not an expert for Grafana
