Thank you for taking the time to report this issue and helping to make
Ubuntu better.
This package failure looks like it was caused by bad ISO download,
corrupted install media, or device failure. eg. look in the logs and
you'll see messages like these :-
Nov 3 21:25:27 ubuntu kernel: [
fyi: the virtual box working probably means the ISO download was okay,
but write to media is at fault. I would still check ISO validity as if
different hardware was used for each, different packages could have been
used for each install & thus the vbox install didn't touch the bad
bits..
