Install incus shell script

[stgraber]

Hey there,

Thanks for this, however I don't think it's particularly likely that someone would go fetch the raw script from Github either by clicking a bunch through the UI or by cloning the repo, just to be able to add/remove the repository.

The installation instructions are simple enough for someone to copy/paste by hand and likely less effort overall.

For those who need to automate things further, an interactive script won't really help them and a non-interactive scripts exist at https://pkgs.zabbly.com/get/incus-stable and https://pkgs.zabbly.com/get/incus-daily which you can even PIPE into a shell if you feel like doing things quickly.
