I'm lucky enough to use english so installing xul-ext-lightning from the ubuntu software center worked as post #12 calls the "correct" solution. I did however have to remove the old lightning addon using the thunderbird add-ons menu to get the new xul-ext-lightning one to show up. Luckily the lightning tasks and events were preserved.
