The link below is about kernel 5.8 issues
for me I had to avoid use the kernel 5.8 thus not will download groovy 20.10 and my choice will be Focal 20.04.2 because if in download section has 2 downloads (groovy and latest focal) sounds how Focal ISO is using kernel 5.4 ? Not.
Focal 20.04.2 ISO use kernel 5.8 and thus not is possible install any Nvidia proprietary driver even previous versions being only possible use Nouveau without CUDA, Vulkan and NVENC.
Any driver being displayed in “Additional Drivers” not will be installed with message about dependences that not will be installed exactly how the screenshot in begin of that topic.
Thus I had tried to install Nvidia driver from nvidia.com, but not is possible install because need some dependences and the new problem not is possible install GCC compatible with nvidia installer.
Trying “sudo apt-get install gcc” not install gcc and is displayed message that not will be installed.
Now see that not is possible use Nvidia proprietary driver and also gcc.
In moment is better return to Focal 20.04.
If you has an Nvidia video card avoid 20.04.2.
Perhaps groovy not has problems with Nvidia drivers.
Is better wait 2 months for 21.00 than install groovy.
Lubuntu is exactly Ubuntu, but I not understand if Lubuntu team can create and 20.04.2 ISO using the previous kernel version 5.4 thus avoiding issues and also not has any information about kernel version in Lubuntu ISO links.
