You beautiful Man/Woman/Other, that solved like 95% of the problem.

I was able to follow that and chroot into my broken install from a liveusb, and get my broken system talking to the internet again to download almost all the broken packages and restore things almost perfectly... Only problem that remains is my networking is nonexistent.

lshw -c network and advance network configuration shows my ethernet device properly, but lshw lists it as disabled, and going into ubuntu network options doesnt show anything.

I've spent about the past half hour working on this, and the various suggestions involved editing /etc/netplan/01-network-manager-all.yaml (on the assumption it was erased/altered/etc, but mine was fine so i didnt touch it), to tryhing to reboot the networking via various commands aginst networkmanager.services and netplan, none of which worked. Most everything else I found was, sadly, from like 10 years ago and i was hesitant to try commands from that long ago for fear of breaking things again/worse.

You've already saved me so much with your first post, so I hate to lean on you further.. but if you have anything that can solve this, I would invent a machine to get you my chocolate cherry from across the internet.

edit

NEVERMIND! FIXED IT!

netplan.io had to be reinstalled, and unlike everything else, apt didnt suggestion netplan***.io*** when i typed in netplan. Network is up and everythings running perfect!

Thank you for everything!
