Comment 141 for bug 1871268

Additional observation: I've tried using Ubuntu LTS 20.04 download images from July and August, selecting the option to install third party drivers. These images worked flawlessly at the end of the summer. But since the mid-September updates, even these earlier iso's of Ubuntu LTS 20.04 Desktop failed with this same install crash. So it would appear that there were changes in late September to things external to the Ubuntu download iso itself.
