[Alfredo Moralejo (amoralej)]

This has been caused by new build of python-ryu-4.13-1.el7, which imports pip library that is not available in servers. Preparing a new build of python-ryu with downstream patch to remove the imports, which are only used for tests, not in actual runtime.

[Alfredo Moralejo (amoralej)]

A new package python-ryu-4.13-2.el7 is being built in CBS and will be push to pike-testing repo as soon as it's ready.

[Alan Pevec (apevec)]

python-ryu-4.13-2.el7 is available in the Pike deps repo and does not exhibit reported trace:
