Ran into same issue and now see a couple of our bug reports so I've linked them as duplicates of yours.
Problem can be solved simply by changing the both "1" in "1 Livepatch update applied since the last restart." (i.e. string 8) and also the "1" in "1 Livepatch update failed to apply since the last restart." (i.e. string 9) to "%d" instead. (Thus there are 2 values to use for the two % len(fixes)) -- You received this bug notification because you are a member of Ubuntu Translations Coordinators, which is subscribed to Ubuntu Translations.
