[asbachb]

Describe the bug
pulseaudio-dlna fails to build due to out of date python version: ERROR: Package 'setproctitle' requires a different Python: 2.7.18 not in '>=3.6'

Looking at the upstream issue tracker and some python 3 - related issues, it doesn't seem to work with python3.

After a quick try, I failed on the missing futures package for python3. It seems this is somewhat hardcoded in the repo: masmu/pulseaudio-dlna#397 (comment)

You might want to see if this can be ported to Python 3 to get it working, but trying to get some Python 2 builds working seems to be a dead end.

[flokli]

There is a python3 branch, though: https://github.com/masmu/pulseaudio-dlna/tree/python3

[asbachb]

Tbh I wasn't aware of the state of that project. Seems to be abandoned: masmu/pulseaudio-dlna#389 (comment)

Should we mark is as broken, remove it or try to get that python 3 branch running?

[flokli]

If the project still has no maintainer (and you're not volunteering either :-P ), I'd rather not ship an entirely unmaintained branch, but remove it for now.

[asbachb]

archlinux for example is using that python3 branch: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=pulseaudio-dlna

[flokli]

… in their AUR. There's no package in the official repositories.

[wamserma]

The comments in AUR point to this repo, which seems to be a maintained fork: https://github.com/Cygn/pulseaudio-dlna

Thanks for marking this closed, totally forgot about that issue ;-)
