Yes, It is probably package issue.

I haven't tried using its deb package but i can run normally portable AppImage version in Ubuntu 22.04 . Maybe you can also try AppImage version. Usually most distro support running AppImage directly (double click to run)

Otherwise:

```

chmod +x /path/to/nostr-relay-tray.AppImage

/path/to/nostr-relay-tray.AppImage

```
