It seems that there are two versions on it, packaged with different names: 2.3.1: https://download.opensuse.org/distribution/leap/15.4/repo/oss/noarch/python3-Sphinx-2.3.1-150400.1.7.noarch.rpm 4.2.0: https://download.opensuse.org/distribution/leap/15.4/repo/oss/noarch/python3-Sphinx_4_2_0-4.2.0-150400.11.6.noarch.rpm It should be noticed that, while we don't decide to remove support for Sphinx < 3, kernel-doc has two different outputs, depending on Sphinx C domain support. The legacy support is enabled with version < 3 [1]. As we're currently discussing dropping support for Sphinx version < 3, I would recommend you to use the 4.2 package. Regards, Mauro [1] Version 3.0 is a bad choice, as the C domain is partially broken.
