[Touch-packages] [Bug 1696415] [NEW] NetworkManager seems to drop IPv4 DHCP lease even though it was successfully renewed

Public bug reported: I've found an issue on some of our Xenial office machines, causing NetworkManager to drop its IP address lease in some cases when it shouldn't. I'm not sure if the actual bug is in NetworkManager or perhaps dbus or dhclient, but I'll do my best to help to figure out where it i

[Touch-packages] [Bug 1696415] Re: NetworkManager seems to drop IPv4 DHCP lease even though it was successfully renewed

By setting log_level to DEBUG, I could confirm from the logs that there is a miscommunication between dhclient and NetworkManager causing this issue. It looks like it is not NetworkManager that removes the IPv4 address from the interface; the address is removed from the interface automatically by

[Touch-packages] [Bug 1696415] Re: NetworkManager does not update IPv4 address lifetime even though DHCP lease was successfully renewed

I've closed down on the root cause being the /usr/lib/NetworkManager/nm- dhcp-helper tool. Occasionally, this binary runs, but fails to correctly send the update to NetworkManager. No errors occur when this happens; NetworkManager in debug mode just says "accepted connection on private socket" then
