Hi After an update to "docker-1.12.6-11.el7.x86_64" the service is unable to start. # systemctl start docker.service Failed to start docker.service: Unit not found. disable/enable/stop is working. I see that the ending is "sl7" where the old package is "el7". What is the SL changes. Anyone know how to fix this ? Downgrading: # yum downgrade docker.x86_64 2:1.12.5-14.el7 docker-common.x86_64 2:1.12.6-11.el7 docker-client.x86_64 2:1.12.6-11.el7 At is works again. -- Mikkel Kruse Johnsen <[log in to unmask]> XMedicus ApS
