Sing-box with atomic desktop

Hello everyone, today I’ve installed fedora silverblue, never used anything like it before.

What is the correct way to install and use something like sing-box (proxy application)? It’s a cli application, so I installed it in toolbox via copr repo. Whenever I try to run it, it just says:

configure tun interface: operation not permitted

Do I just install it on the host system with rpm-ostree install? This just feels a bit wrong so I’m asking.

Hello @tentaishen and welcome to :fedora: !

There’s nothing wrong with package layering. If you’re not sure how to do it, check out Adding external package repositories.
