I have managed to bypass this problem by manipulation the Python code of the upgrade process. But it is far easier to bypass it properly by setting up a config file in /etc/update-manager/release-upgrades.d/*.cfg.

According to http://askubuntu.com/questions/425355/error-authenticating-some-packages-while-upgrade one needs to create a file /etc/update-manager/release-upgrades.d/unauth.cfg with the contents:

[Distro]
AllowUnauthenticated=yes

The upgrade runs smoothly through.
