Arch Linux User Repository

PR I mentioned has been merged, but this version is still pinned to a tag. For now, I'd recommend installing https://aur.archlinux.org/packages/streamcontroller-git or using the patches below.

Independent of whether streamcontroller it is already installed:

1. Save the diff below as ~/Downloads/requirements.diff
2. (Try to) install via yay -S --answerclean All --answerdiff None --rebuildall streamcontroller – this will lead to the error
3. Apply the patch via patch ~/.cache/yay/streamcontroller/src/StreamController-1.5.0-beta.13/requirements.txt < ~/Downloads/requirements.diff – this applies the patch to the requirements.txt that was previously downloaded and extracted in the yay cache
4. Install via yay -S --answerclean None --answerdiff None --mflags="-e" streamcontroller – this re-runs the make/install process without cleaning up (download/extract) the cache first
5. Party!

On a fresh install, how can the requirements.txt be patched? Or is this something you can do @NOSDuco? At least until the github issue you posted is merged?

Hey all, aware of the python3.14 issue. Please follow @Treyfane's recommendation for now, and once https://github.com/StreamController/StreamController/pull/532#issuecomment-3740476012 is merged, it will be fixed downstream.

The Levenshtein – and subsequent RapidFuzz error – can be avoided with the following patch to requirements.txt in the source:

As far as I can see everything works after …

Today's python update to 3.14 breaks streamcontroller with the error:

python: error while loading shared libraries: libpython3.13.so.1.0: cannot open shared object file: No such file or directory

Hey, plugin installs are borked atm. Streamcontroller relies on it's own plugin install tools that are not provided by this package.

With update to beta 11 the issue with the missing icon is also gone. :)

@NOSDuco thanks for your adjustment. The only thing which is not working is the missing icon in the status line of KDE/Plasma dark theme.
