There are hard problems with the new updates on 20.04.1-LTS:
Kernel 5.8.0-36-generic lacks lots of drivers (mostly network (ethernet/wifi)).
New NVIDIA drivers brake old kernels (5.4.0) and even in 5.8.0-36 aren´t working properly:
2.1) In a Predator Helios only the HDMI port renders plasma (X11)
2.2) In the same computer the native display is not detected by X11
2.3) In old kernel the NVIDIA driver is not installed by kmod daemon
Please, in LTS check things before putting them into production...
