Test case seems to be working fine here; I'm using the Lenovo 3000 laptop which this bug was preventing me upgrading.
update-manager --proposed started up an instance of the Update Manager that offered me a button to upgrade to 8:04.
Upon pressing that button I was asked for a password, taken through the information panels about what would happen and asked to confirm.
On confirmation, the system has started the upgrade. It is currently downloading the files; sadly it appears that traffic shaping is quick to cut in, so it will be midnight here before they are all downloaded.
However, it is behaving correctly so far, thus I believe the workaround/fix as uploaded to 'proposed' works properly.
