Description:

Chrony supports the kernel PPS interface, but it will not support this if built with PPS tools headers not present. The kernel PPS interface is required for accurate timekeeping.

Additional info:

package version(s) 4.3-1
config and/or log files etc. n/a
link to upstream bug report, if any n/a

Steps to reproduce: Configure chrony to use a PPS refclock, example: "refclock PPS /dev/pps0 lock NMEA refid GPS" in /etc/chrony.conf Expected behavior: chronyd uses kernel pps0 source Observed behavior: chronyd cannot start because PPS support is not compiled in

Fix: Compiling chrony with pps-tools package present solves this issue
