I did this, and when it rebooted, it did disk checks, but then failed to mount anything, so I rebooted into Linux Mint (also installed on this PC) and did a disk check of Ubuntu from gparted, which did not find any errors. The good news is that when I rebooted again and booted into Ubuntu, it booted okay, and it offered the libgmp10 file in the Update Manager, so I installed it that way. I also did a sudo apt-get autoremove in a CLI and that worked too, so no more problems with dpkg it seems.
