Simplest fix for this was the one described in this AskUbuntu answer: http://askubuntu.com/a/772324/186141 there's no need to downgrade package or use usb sticks to download update on other computer, just launch internet manually and update your computer. sudo ifconfig eth0 up sudo dhclient sudo apt-get update sudo apt-get upgrade -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1581617 Title: upgrade of libnl-genl-3-200 causes networkmanager to not load Status in network-manager package in Ubuntu: Confirmed Bug description: This morning, before leaving for work, I saw there was a update available for a package in Ubuntu 14.04 (I do NOT have the -proposed repositories enabled). I installed it and shutdown. When I got to work, no internet (network-manager won't load, there's a general protection error in dmesg). Looking at the apt log /var/cache/apt/history , it looks like libnl- genl-3-200 was updated (and that was the *only* package that was updated). After loading up synaptic, there are other "upgradable" packages, none of which got installed (or were listed) when I upgraded libnl- genl-3-200: gir1.2-netowrkmanager-1.0 libmm-glib0 libnm-glib-vpn1 libnm-glib4 libnm-util2 modemmanager netowrk-manager However, without the internet, I can't get these packages! Please help! I *did* have an older version of libnl-genl-3-200 in /var/apt/cache/archives (from Jan 29), but installing this and restarting networkmanager (or the machine) does not fix the issue.
