[Bug 1912034] Re: At end of install process, installer said "fatal error"

[Ken T]

Thanks, Chris. I guess we can chalk this one up as an edge case, as I
imagine that most folks just install one (or maybe 2) OS's, and maybe
people who are doing multi-boot installs could be assumed to know enough
to easily sort that out without further prompting/guidance from the
installer itself.

I suspect that in my case, the easier option might simply be to back up
my data to an external drive, then obliterate the existing partition
table and just install Mate freshly over the top of it. A crude method
perhaps, but it should work easily enough.

Thanks again for your help - unless you want to comment further, I am
happy to close this ticket now.

Cheers,
Ken.

Title:
  At end of install process, installer said "fatal error"

Status in ubiquity package in Ubuntu:
  New

Bug description:
  ...and yet another dialogue box said "Installation complete. You need
  to restart the computer..."

  This happened while installing Ubuntu Mate 20.10 onto a partition
  alongside other existing partitions with Ubuntu & Linux Mint installed
  on them. I nominated the new partition with Ubuntu Mate (sda5)
  mountpoint as root, as the installer wouldn't let me continue without
  doing so, even though I had done this previously with other installs
  alongside this one on the same laptop, and Grub 2.x is already on this
  computer & has worked fine at bootup.

  Thanks,
  Ken.
