I’ve been noticing this all day, and so I took a look at http://dev.centos.org/centos/7/systemd-container/ just now. I see a new package! I ran yum install systemd-container-EOL, and it’s fixed my problems so far… I don’t know what timezone that timestamp is in, or if we are SUPPOSED to magically know to install that, but when I do something akin yum update BOTH that EOL package and the real systemd and systemd-libs try to install… But manually installing systemd-container-EOL first made all my problems away.
Before yum install systemd-container-EOL, docker run centos:7 yum update resulted in trying to installed systemd-container-EOL, systemd, AND systemd-libs. After, none of them.
I just want to say I don’t REALLY think this is the right place to post either, but I couldn’t find this ANYWHERE else! (except https://bugs.launchpad.net/fuel/+bug/1526005 did), I’m sure it’s on some centos thing somewhere… So thanks @kasisto for posting here at least! Hope this helps you too.
