Just downloaded the most recent update today. After restart, I have no networking capability whatsoever. No wifi, no wired, nothing. Opening networking through settings gives me an error message to the effect of "your network settings aren't compatible with this build " (can't remember the exact wording. Without any internet, I can't download any updates or try to undo the last one. If it matters, I'm using a Lenovo yoga laptop. Help!!!
Because this is most visited question regarding this topic on Elementary OS, I have solution for you
To cite the answer:
and you need to downgrade these packages
The first link helped me, hope it will help you too
I had the same problem and downgrading the
libnl packages worked too.
I rebooted using a live USB , downloaded
libnl-route-3-200_3.2.21-1_amd64.deb from http://archive.ubuntu.com/ubuntu/pool/main/libn/libnl3/ , installed it using
dpkg -i and rebooted.
Internet should be working now.
