[Bug 1514142] [NEW] Unable to upgrade to 15.10, even with a fresh install

[Stuart Soloway]

Public bug reported:

The package named is my best guess, but I'm not certain.

What happened is that I was running Ubuntu 14.<something> and I decided
to upgrade to the latest.  So I downloaded an installation DVD and did a
fresh boot from it, wiping out everything and reformatting the hard
disk.  (I had nothing on the computer that I wanted to save.)

The update hung with the progress-bar 30% finished.  After many hours I
gave up and forcibly powered it down.  After that I was able to get to
BIOS, but saw no indication of the existence of GRUB (of course I may
not have known where to look).  If I let it proceed, I would see a
screen with a text cursor in the upper left corner.  When I would hit
any key I would hear a beep, so I guess that means some code was
running, but nothing else would happen.

I got the same result with the alternate install disk.

I did various diagnostic stuff that is described in this thread:

   [SOLVED] Install of Lubuntu 15.10 may have wiped out GRUB

I marked it solved because I was able to recover by installing (fresh
install, with disk-format) 14.04 and then installing 15.10 as an upgrade
(not a fresh install).  So my problem was solved.  But it still seems
like there is something funky going on with the 15.10 installation
software, so I'm reporting it here.

My hardware was an 3680-2682 with 1GB of RAM, upgraded from the original
500MB.
