Note that bug 1642966 which many people observed when updating is not caused by the changes of this SRU (small patch removed from CUPS daemon). So do not worry and apply the workaround shown there, should you also run into a problem with the update. Once your installed CUPS packages being 2.1.3-4ubuntu0.1 please test whether this bug (CUPS web interface stops responding) is fixed. Thank you.
