Comment 4 Tuomo Soini 2018-02-26 08:19:02 UTC

python-crypto is on rhel7 extras - it shouldn't be in epel7. Exactly same NEVR is provided by rhel7 extras now.

Comment 5 Paul Howarth 2018-02-26 09:08:02 UTC

Tuomo, is python-crypto available for all EL-7 architectures? I have no visibility of RHEL7 repos myself. If it's available everywhere, I'll retire python-crypto from EPEL, otherwise I can do a limited-arch support package based on what's in CentOS git.
