clock_adjtime()을 호출할 수 없습니다. systemd-timesyncd 실행이 허용되지 않는 작업 - 관련 권한이 있을 수 있습니다.

Linux 5.10.103-v7l+를 실행하는 Pi 4B에서 systemd-timesyncd 장치가 실패합니다.

  UNIT                      LOAD   ACTIVE SUB    DESCRIPTION                 
● systemd-timesyncd.service loaded failed failed Network Time Synchronization

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed.
To show all installed unit files use 'systemctl list-unit-files'.

너무 많은 시도 후에 실패할 때까지 systemd-timesyncd가 시작되고 중지되는 것을 Journalctl에서 볼 수 있습니다.

I tried running it with debug logging using the same user that is running it, systemd-timesync:

This shows why it is failing.

If I run it as root using sudo, I don't get that error and it appears to be working:
