Ok, it seems after eliminating the above issue the sys_ptrace isn't triggered anymore. And even if it is it seems not required for the functionality and would be rather unsafe.
Until I get a GPS lock chrony sees: chronyc> sources 210 Number of sources = 10 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== #?

After a while (and depending on signal quality) it syncs to the PPS. chronyc> sources 210 Number of sources = 10 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== #x GPS 0 4 177 24 -876ms[ -876ms] +/- 200ms #- PPS 0 4 177 21 +916us[ +916us] +/- 63us ^- chilipepper.canonical.com 2 6 37 53 +33us[ +33us] +/- 33ms ^- golem.canonical.com 2 6 37 52 +448us[ +448us] +/- 43ms ^- alphyn.canonical.com 2 6 73 50 +552us[ +552us] +/- 110ms ^- pugot.canonical.com 2 6 37 52 -429us[ -429us] +/- 50ms ^- a08.alphasrv.net 2 6 37 53 +1943us[+1943us] +/- 52ms ^- dns02.xstream-labs.com 2 6 37 53 +568us[ +568us] +/- 36ms ^- stratum2-3.NTP.TechFak.U> 2 6 37 53 -861us[ -861us] +/- 14ms ^* mail.masters-of-cloud.de 3 6 37 54 -45us[ -593us] +/- 12ms Note sometimes it considers the GPS/PPS too noisy, but that might be right as I don't have the most pricey receiver nor the best reception. Or it considers (after a while) the PPS as good, but had already settles on a server and is not combining PPS with it despite the order of magnitude better resolution) More antennas arriving later this week ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872175 Title: gpsd unable to open chrony PPS socket To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/1872175/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
