[Bug 1884050] [NEW] executing grub2 installation /dev/sda6 failed, this is a fatal error.

[Jack Tompson]

Public bug reported:

A few months ago, i used ubuntu alongside windows 10. At that time, the
laptop was slow due to the dual boot, after that I erased Ubuntu. Now
I'm trying to reinstall Ubuntu 20.04 LTS(even tried old versions) and
nearly at the end of installation, there is a fatal error 'executing
grub-install /dev/sda6 failed'. I googled and couldn't find solution to
this problem
