Public bug reported: This error occurred on upgrade to Yakety.
I wonder if this is the same as LP #1189138 "package gnome-nibbles (not installed) failed to install/upgrade: subprocess installed post-removal script returned error exit status 1" which is from a few years ago and marked fixed release.
