Current cocpit packages are conflicting, which is preventing the host update:
....
Transaction check error:
file /usr/share/cockpit/networkmanager/manifest.json from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch
file /usr/share/cockpit/networkmanager/po.ca.js.gz from install of
cockpit-system-176-2.el7.centos.noarch conflicts with file from
package cockpit-networkmanager-172-1.el7.noarch
....
Looks like a current packaging of cocpit is wrong, it doesn't upgrade
existing version.
To solve it simply:
yum remove cockpit-networkmanager-172-1.el7.noarch
yum clean ;yum update
all fixed.
