Public bug reported:
I am unable to change any settings within network-manager for any wired
interface (not tried wireless) - if you try to change anything (i.e dns
servers, ipv6 settings, change from dhcp -> dhcp address only) you get
an error (and the setting doesn't change)
i.e - in this example I selected 'require IPV4' and I get
May 5 09:13:08 mcox-N552VW NetworkManager[810]: <info>
[1462435988.7023] audit: op="connection-update"
uuid="c91931f0-15d1-4d29-9b76-e80ef5a4abcd" name="Wired connection 1"
result="fail" reason="connection.gateway-ping-timeout: can not set
property: value "34184640" of type 'guint' is invalid or out of range
for property 'gateway-ping-timeout' of type 'guint'"
(similar errors occur if you try to change any setting)
This is happening on multiple machines.
As a 'work-around' you have to remove the interface and re-add to change
settings.
