yum clean all may fix it, but I'm not sure where that should run - https://forums.centos.org/viewtopic.php?t=70183

Photon 3

Created symlink /etc/systemd/system/multi-user.target.wants/consul.service → /etc/systemd/system/consul.service.
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /lib/systemd/system/docker.service.
A dependency job for docker.service failed. See 'journalctl -xe' for details.
 [fail] docker is Active: inactive (dead)

Not sure why Docker isn't running or what the dependency is that is failing

CentOS 7 has fixed itself, but Amazon Linux 2 is now experiencing the same issue

In the photon3 test, the docker failures are actually irrelevant. The issue is that libseccomp is currently uninstallable.

Opened vmware/photon#1090 upstream

The photon3 test needs a rebuilt image, so will be fixed after weaveworks/footloose#256 and we start using that new image. In the mean time, this is ready to merge for the Centos fixes and the footloose images version bump
