Hi,

h5py fails to build with Sphinx 3.1, currently available in
experimental.

Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> dh_installdocs
> grep "https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js" debian/python-h5py-doc/usr/share/doc/python-h5py-doc/html/* -R --files-with-matches | xargs sed "s|https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js|file://usr/share/javascript/mathjax/unpacked/latest.js|g" -i
> sed: no input files
> make[1]: *** [debian/rules:122: override_dh_installdocs-indep] Error 123

The full build log is available from:
   http://qa-logs.debian.net/2020/06/23/h5py_2.10.0-8_unstable_sphinx-exp.log

Please see [1] for Sphinx changelog, which may give a hint of what changes in
Sphinx caused this error.

Also see [2] for the list of deprecated/removed APIs and possible alternatives
to them.

Sphinx 3.1 is going to be uploaded to unstable in a couple of weeks. When that
happens, the severity of this bug will be bumped to serious.

In case you have questions, please Cc sphinx at packages.debian.org on reply.
