Running "file /usr/bin/sphinx-build" says: /usr/bin/sphinx-build: Python script, ASCII text executable Randy, how did you install the sphinx-build? And which distro are you on? > > I don't see what is causing this, so I am using the previous day's > linux-next for Documentation testing etc... Another question ... Does going back to a past linux-next make sphinx-build work again? If that's the case ..., I'm not sure, but it might be related to Mauro's sphinx-build-wrapper, which is now in docs-next (not in docs-mw for v6.18 at the moment). Randy, what happens if you revert the latter part of Mauro's series, namely, 819667bc3ccd ("tools/docs: sphinx-build-wrapper: add a wrapper for sphinx-build") 2e1760999e58 ("docs: parallel-wrapper.sh: remove script") ... up to ... 42180ada39da ("tools/docs: sphinx-build-wrapper: add support to run inside venv") on top of next-20250919 ?
