Shortwave is a cool webradio player designed with the Librem 5 in mind. François and likely many others want it, unfortunately it's not packaged in Debian. Its sources can be found here: https://gitlab.gnome.org/World/Shortwave.
This is the content of a Matrix chat I had with the Felix Häcker in this room https://riot.im/app/#/room/#shortwave:matrix.org
jeremiah_: Hello gentle wizards!
I'm interested in packaging Shortwave for Debian / PureOS
Felix: Hello 🧙!
There's no stable version of Shortwave available yet, I would wait for the first release.
There's already some DEB packaging work done here in form of a Ubuntu PPA: https://code.launchpad.net/~shortwave-developers/+recipe/shortwave-daily
Packaging is currently a bit difficult, since rust/cargo requires internet to build Shortwave, to download the rust crates.
But later when there's a release, there will be a "vendored" package which includes all dependencies, so it's possible to build it without internet.
jeremiah_: That sounds great Felix - thanks for the info!
We have some folks at Purism who're clamoring for this to get into our repos. :-)
Felix: Glad to hear that :)
