Re: [PLUG] Ubuntu 16.04 upgrade problem


Just tried that. Did not work. Funny thing is dhclient release and renew still brings the network back.

I might have been wrong about needing to start network-manager manually. Now I just need to do a release and renew with dhclient.

For a quick workaround try setting it up with static network addressing and see if that works and is stable.

Poor timing on my part. I donated a computer to a senior center, and just upgraded it to 16.04. I am running into a problem, and about to leave town.


The upgrade indicated that it had a problem and needed to roll back, however after I rebooted at the end it was showing the OS as 16.04. The problem is that the networking is not coming up automatically. I can start it manually with


service network-manager start

dhclient –r



Additionally, if I use settings | network and turn the network off and on, networking will again stop working, however network-manager is still working, because at that point, if I just release and renew dhcp (dhcient) then the network will come back. I can try setting a fixed ip address, but I do not think that is going to work because network-manager is not coming up.


I need at least a quick work around. Any ideas?
