Thank you for taking the time to report this bug and help to improve Ubuntu.
This looks like a manifestation of a bug in dpkg's triggers handling; being configured is not a bug in ntpdate. The following portion of the log file is probably the actual failure: Processing triggers for ufw ... Can't locate auto/DynaLoader/dl_findfile.al in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /usr/lib/perl/5.10/DynaLoader.pm line 164 Compilation failed in require at /usr/share/perl/5.10/fields.pm line 122.
