Unable to connect to Internet via WiFi or Ethernet on Ubuntu 18.04 No network icon. No wifi adapter found. I can however connect WiFi on Windows.
Lshw gives the following output

I had installed kvm and libvirt earlier today for Android studio after which I had a very tough time trying to log into my Ubuntu. Purged Nvidia in recovery shell.
Most answers on the internet assume I can connect either though tethering or Ethernet cabel but both are not working in my case.
