It happened to me too. Fist when I tried a (really quick & dirty upgrade without uninstalling tons of 3rd-party software & repositories) the system did upgrade but was quite unstable (go figure) so I did a new fresh install, as my /home is a separate partition. Now the system is up and running again but update manager keeps suggesting to upgrade to the new release.
