@maribu, the VCS hosting bug is open for quite a while now, no one is assigned to it and it looks like this is an unmaintained platform. I see no reason to report there. Posting here that the hosting platform is broken is very much relevant to get feedback from wlrobs' developer. If he still sticking to this broken platform it means he doesn't care about distribution and that's fair enough, people can have their private projects. I just won't bother package maintainers like the Flatpak one to bundle wlrobs.
This is still unusable,
https://hg.sr.ht/~scoopta/wlrobs/archive/v1.0.tar.gzis not cached, it gives a different hash on each download, not suitable for packaging. I'm giving up on this, XDG Portals is the way to go anyway.
Thanks for responding, I think I'll wait on the archive checksum issue.
As a proof-of-concept, I posted some test builds.
So I tested the other day wlrobs with the screencopy backend in a Flatpak and it worked pretty great.
Flatpak-builder only supports Git for VCS, and the auto-generated archives from commits
https://hg.sr.ht/~scoopta/wlrobs/archive/<commit-sha>.tar.gzare not reproducible (different hash for each download).
I don't know what the OBS Flatpak app maintainer thinks of wlrobs and if he would accept a PR adding it, but the minimum requirement is most likely a tarball release or a Git mirror source.
