The Ubuntu 20.04 Desktop Live CD installer crashes when trying to install. Installing without updates succeeds, but results in a broken install (no ethernet, or dkms for some reason).

How the error occurred:
 - Run Live CD (normal graphics mode)
 - Run installer
 - Select "Minimal install" and "install third-party software"
 - Set up partition table (2GB EFI partition, rest of disk Ubuntu)
 - Installer crashes at last stage

Expected behaviour: Installer doesn't crash
Actual behaviour: Installer crashes.

Note, I have installed ubuntu 20.04 on this system before, so I have no idea why the installer would crash here.

EDIT: Problem appears to be caused by nvidia-driver-440 package. Installing with 21.10 (which defaults to nvidia-driver-470) appeared to fix the problem.
