The following fails on Fedora Rawhide (F31):

# dnf install httpcomponents-core

No match for argument: httpcomponents-core

This breaks pki-ca:

(try to add '--skip-broken' to skip uninstallable packages)


Please rebuild httpcomponents-core for F30 and F31. Note that this package is maintained as an ursine package as per here: 

https://src.fedoraproject.org/rpms/httpcomponents-core/tree/master



Note that I grabbed httpcomonents-client from its last Koji build as it also isn't installable: https://bugzilla.redhat.com/show_bug.cgi?id=1708363
