This *really* shouldn't happen and is a bug that needs to be addressed,
regardless of any of the other stuff here.  The logs in /var/log/apt/
and possibly /var/log/dist-upgrade/ may help to figure out why the
package management system felt it needed to do this.

Booting in a completely different firmware mode, which is the effect of
switching between grub-pc (BIOS) and grub-efi (UEFI), could easily make
a difference here.
