I hope you can resolve/ revert this ASAP as it brings network down and finding information on how to fix it becomes very complicated.
Anyway another solution to revert to the working packages is: if you have an Ubuntu USB stick somewhere 1. Boot "try out Ubuntu" 2. mkdir installation 3. sudo mount /dev/sdXX installation # where sdXX is your ubuntu root partition 4. sudo chroot installation 5. apt-get install libnl-3-200=3.2.21-1 libnl-genl-3-200=3.2.21-1 libnl-route-3-200=3.2.21-1 this saves you manually downloading and copying the packages -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libnl3 in Ubuntu. https://bugs.launchpad.net/bugs/1539513 Title: networkmanager segfaults with 3.2.21-1ubuntu1 Status in libnl3 package in Ubuntu: Confirmed Bug description: Description: Ubuntu 14.04.3 LTS Release: 14.04 After upgrading to 3.2.21-1ubuntu1 network-manager 0.9.8.8-0ubuntu7.2 segfaults: [ 21.367977] init: network-manager main process (1000) killed by SEGV signal [ 21.367989] init: network-manager main process ended, respawning [ 21.424932] init: network-manager main process (1060) killed by SEGV signal [ 21.424943] init: network-manager main process ended, respawning [ 21.451519] init: network-manager main process (1066) killed by SEGV signal [...] xxx@yyy:/tmp/bla# gdb /usr/sbin/NetworkManager CoreDump [...] Reading symbols from /usr/sbin/NetworkManager...(no debugging symbols found)...done.
