The bug report was submitted from a different machine than the one the installation failed on.

The Ubuntu Release Notes, https://wiki.ubuntu.com/FocalFossa/ReleaseNotes#Installer_and_live_session, mention an issue with nouveau crashing during the installation process. You might take a look at those and see if the work around helps you out.
