Public bug reported:
I have a GPS reference clock that has been working fine with legacy ntp
on Ubuntu 22.04.4 LTS for several years.
Upon upgrading to Ubuntu 24.04.1 LTS the legacy ntp package was replaced
with ntpsec and ntp no longer recognizes that there is a pps source.
I have verified that NEMA data is still flowing and /dev/pps0 is still
providing a pps signal. The tools from the pps-tools package all still
work.
I modified the ntp.conf to conform with ntpsec:
refclock nmea mode 16 minpoll 4 iburst time1 -0.0007 flag1 1 flag2 0
flag3 0
I also tried the shm driver and pps was still ignored.
ntpq -p reports: NMEA(0) .GPS. 0 l - 16 0
0.0000 0.0000 1.9531
I have been unable to find any relevant error message in any log file.
Given that the only thing that no longer works properly is ntpd leads me
to suspect that either ntpd is broken or during the package installation
some permission or setup parameter was hosed in the switch to ntpsec.
