Hi, Sending this to spread information. I have encountered and issue with Centos 7.4.1708 (Core) when compiling the oVirt engine. The pep8 validation was not passing correctly. It turned out, that the Centos has the old and bugged version present by default. The solution is to use the same version as used in oVirt CI. Just add http://resources.ovirt.org/repos/ci-tools/el7/ to yum.repos.d and it will start passing again. Best, Petr
