Now that rpm 4.19.91 AKA 4.20.0 alpha 2 is in Rawhide, there are some regressions in the %check section.

The line

  bash -x ./tests/test_data/build.sh

fails as follows:

+ umask 022
+ cd /builddir/build/BUILD/packageb-2-build

RPM build errors:

If I comment out that script, then the Python tests have 199 errors due to a CalledProcessError invoking that script.
