Lucky for you, upgrading from 20.04 to 20.10 is easy. This option is preferred over manually upgrading the kernel, because 20.10 fully supports the 5.8 kernel and so should be more stable. So you have two options: Update to Ubuntu 20.10 You need a kernel version 5.8 or newer, it's got all the new cool drivers.
