[Bug 1897301] [NEW] Trying to re-install 20.04 choosing option 1 (erase and re-install) and the installer gets this error.

[Montecreasor]

Public bug reported:

My Nvidia graphics card stopped loading on Ubuntu 20.04 yesterday (works
find when I boot to Windows 10) so I've found that the only way to get
it to work again with Ubuntu is to re-install the OS.

After choosing install option 1 (erase 20.04 and re-install) the
installer fails and asks me to log this error.

Please respond ASAP since I can't use my Thinkpad P70 until you fix this
issue.
