+ntp (1:4.2.8p8+dfsg-1ubuntu2) yakkety; urgency=medium
+
+  * remove disabling of sntp (LP: #1604010)
+    - d/rules: remove --with-sntp=no
+    - d/rules: remove --disable-local-libopts to make sntp build properly.
+      Otherwise via libopts and autogen it will crash into
+      'error: ‘EX_SOFTWARE’ undeclared'.
+    - debian/ntp.install add sntp binary
