Maybe give nostr:npub1gp4xzpmluelsakjtayc4wtzj97fhj5kakqjvsannu00xkdlf4x8s0xdqyq a try. It's in flutter which can build a linux or windows native app.

I haven't still automated the builds for linux, but if you can get the source and flutter build linux maybe will work.

Happy to help and discuss PRs to the code.
