The release upgrade failed to calculate because you have installed nodejs from a location other than the official Ubuntu archive. This version of nodejs is greater than the one in the archive and is keeping some python packages installed which then prevents the upgrade from being calculated. Please remove nodejs and then try the upgrade again.
