[Bug 1895161] [NEW] Ubuntu installer crashes - Unable to install GRUB in /dev/sda

[Juan C. Alvarez]

Public bug reported:

I attempted to reinstall ubuntu (a newer version) on a system because
the older version stopped working. I think it was an unsuccessful
upgrade which damaged the older version along with the GRUB. When
attempting to reinstall, it won't be able to install the GRUB at the end
of the installation process.

I don't remember the number of the old version (I think it was 18.x),
and I'm trying to install the most recent (20.x)
