Not sure why only the optional dependencies CI job fails, but the error seems relevant:

(Note: ⚙️ Push updated logo files is a temporary commit to verify that the "binary files... differ" error suggests that the git-lfs tracked logo files are still lingering somehow.)

[pavithraes]

Well, I don't think I understand git-lfs well enough to know how that error fixed itself. I only deleted the old PR branch and cleaned up my local git caches. 🤷🏼‍♀️

However, I did try re-running the optional-dependencies CI, and it seems to pass consistently now.

[pmeier]

Ok, the reason that only the optional dependencies job is failing is because it is the only one which uses a git command:

ragna/.github/workflows/lint.yml

Lines 27 to 30 in b7c5cff

	- name: Test optional dependencies
	run: |
	python scripts/update_optional_dependencies.py
	git diff --exit-code

Still trying to figure out why the error happens though.

[pmeier]

Ok, I can reproduce the issue when checking out Ragna on a system that doesn't have git-lfs installed.

@pavithraes Found the issue. You reset the type to text here, which led to the files being compared as text although they are binaries.

Thanks @pavithraes!
