Comment 1 Michael J Gruber 2026-03-27 20:54:35 UTC

FYI: The fix for the requires is simple, but the build still fails because of 3 test failures in test_norm_callback, test_pcolornearestunits[png], test_rcupdate.
The latter two may be due to changed ghostscript or image libraries (too strict image diff), but the first one is mysterious.

I know what is happening here, reported in https://github.com/matplotlib/matplotlib/issues/31429 with proposed solutions. I've built the patched package in the COPR so we should be able to continue the rebuilds.

Comment 3 Elliott Sales de Andrade 2026-03-31 23:27:12 UTC

The missing Requires would be fixed by rebuilding the texlive packages with the new automated Provides generator. The missing ones for this package are in the `texlive-cm` package, which is a subpackage of `texlive-collection-basic` now in Rawhide/F44. cc @spotrh 

The other issues should be handled upstream.
