Comment 13 for bug 1820892

Looks like the python 3 parsing from pypi is failing:

We should be looking up the package name correctly by splitting off the blacklisted versions:

package=$(echo $package_dir | grep -o '^[.a-zA-Z0-9_-]*')
python3_classifier=$(check_python3_support_for_package_remote $package)

$ echo libvirt-python!=4.1.0,!=4.2.0 | grep -o '^[.a-zA-Z0-9_-]*'
libvirt-python
