Description Miro Hrončok 2026-01-28 11:24:47 UTC

- texlive-substitutefont-11:svn32066.0.1.4-81.fc44.noarch Requires texlive-base
- texlive-base-12:20250308-99.fc44.x86_64 Obsoletes texlive-substitutefont <= 11:svn32066.0.1.4

Hence, the package is not installable in Koji.

This, in turn, makes python-sphinx FTBFS: https://koschei.fedoraproject.org/package/python-sphinx

Reproducible: Always

Steps to Reproduce:
$ mock -r fedora-rawhide-x86_64 --config-opts mirrored=False install 'tex(substitutefont.sty)'
Actual Results:

Expected Results:

Comment 1 Tom "spot" Callaway 2026-01-29 12:36:12 UTC

Yup. So, here's the deal:

The "new" texlive packages all have an Epoch of 12. They're not all in Rawhide yet, but we're getting closer every day. One of the "big" collection packages that was missing was texlive-collection-latexextra, which has the newest texlive-anyfontsize inside it. That's getting uploaded to git as I type this and should be in rawhide in an hour or less, and should get us closer to texlive-base being installable again (as a whole).

But that's not quite the python-sphinx problem. The python-sphinx problem is that it has a BuildRequires: tex(substitutefont.sty), but that component is no longer upstream. Sure enough, sphinx doesn't actually depend on the obsoleted substitutefont tex component (anymore) and has created a wrapper in sphinx/texinputs/sphinxpackagesubstitutefont.sty. When I comment out that incorrect BuildRequires, python-sphinx rebuilds in a rawhide mockbuild (even with the mix of epoch 11 and epoch 12 tex packages).

Comment 2 Miro Hrončok 2026-01-29 12:49:55 UTC

Thanks for checking. We'll get the BR out.

Comment 3 Miro Hrončok 2026-01-29 12:51:09 UTC

FTR here is how/why that BR was added: https://src.fedoraproject.org/rpms/python-sphinx/c/0009cf4a25c6cb7fb415c74cb1c53b9162f8838a?branch=rawhide

Comment 4 Tom "spot" Callaway 2026-01-29 12:57:10 UTC

And that commit was probably correct 3 months ago when Fedora's texlive was two years out of date. It's plausible that the substitutefont removal hadn't been worked around in that version of sphinx, not sure, and I'm not going to deep dive to figure it out since the fix is straightforward.

Comment 6 Tom "spot" Callaway 2026-02-09 16:10:56 UTC

Closing this out.

Comment 7 Miro Hrončok 2026-02-09 17:28:22 UTC

Indeed, this now gets:

  No match for argument: tex(substitutefont.sty)

Which is expected. Thanks.
