Rebooting is fine.  You certainly do not need to reinstall.  You can
probably recover by repeating the upgrade of just
linux-image-5.0.0-13-generic (i.e. "apt install
linux-image-5.0.0-13-generic"), and then continuing with anything else
that wasn't upgraded ("apt full-upgrade"); if that fails then post the
full transcript.
