Hi Etienne, I've noticed that conda (22.9.0) does not build as well, and have resolved the issue in my local guix clone.
It required these changes: - Add python-conda-package-streaming 0.7.0. - Upgrade python-conda-package-handling from 1.7.3 to 2.1.0 (which has python-conda-package-streaming as a dependency). - Remove python-anaconda-client as a dependency of conda. - Make conda a dependency of python-anaconda-client. I'm also relatively new to guix. I think it is prefered to have small patches, so I will send four patches for each of the above steps to this issue as described in [1]. Then hopefully someone will review them and merge them. Then after that it might be worthwhile to update conda itself too. Some notes: - python-conda-package-streaming has conda itself as an optional dependency for testing. I have therefore disabled all the tests. - python-conda-package-streaming also removes the need for libarchive, which apparently required some workarounds, so those are also removed. - It is not clear to me why python-anaconda-client was a dependency of conda in the first place, so maybe I'm missing something. - I've also fixed some linting warnings on the existing packages.
