I had this issue in the past. After the BIOS update, 20.04LTS is loading up(though slowly)-but no internet connection(even when i am using Ethernet cable and it works fine in Windows 10-so no hardware issue). Graphics driver is also not loaded. Yes, I am talking about multiple issues but i want to focus only on networking right now. I cannot login to 18.04 LTS strangely.
Tried this and this but no luck
Output of ip a or ifconfig
Output of lspci -knn | grep Eth -A3
Output of sudo dmidecode -s bios-version

Finally I got fed up of login into ubuntu linux - try out one command after the other, take the snapshot from phone and then post it here to go no where. Decided to install Ubuntu Linux all over again. Install detected 20.4 LTS already and gave me the option to install 20.4.1 LTS along side it. Tried that option but it also messed up. Was getting the black grub 2 screen and nothing else. Tried boot-repair from live USB and it's back.
Better to always install fresh rather than upgrade or rely on others suggestions.
