[Bug 1539513] Re: networkmanager segfaults with 3.2.21-1ubuntu1

 

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
