Running Xubuntu 20.04.01. Got the popup this morning that updates needed to be installed so I clicked okay and rebooted when finished. After reboot the network is gone and the server is a large brick since it can't get on the network. Tried holding shift during boot to see a grub menu to maybe boot into the previous kernel but no grub menu ever appears, it always just boots into this broken 5.8.0 kernel. Not sure what to do. Who knew an average, ordinary software update could brick my machine?

Any ideas how to get my network back?
