Hello Leroy,

Probably not all packages were downloaded/installed.
Depending on where you were on the upgrade process the Crtl-c may try to
reverse the install.
You can use the livecd to boot/chroot into that installation, check if your
apt config is pointing to xenial repositories (something like grep
xenial /etc/apt/sources.list should output several lines) and then try to
finish it: sudo apt update + sudo apt dist-upgrade.
