无法将时间同步到Ubuntu 19.10上的网络服务器
无法将时间同步到Ubuntu 19.10上的网络服务器
提问于 2020-01-15 00:23:14
三周前升级到19.10，从那以后，我无法让系统与时间服务器同步。
我所做的：
xxxx@asgard:~$ cat /etc/timezone
America/Los_Angeles
marc@asgard:~$ timedatectl
Local time: Tue 2020-01-14 15:18:24 PST
Universal time: Tue 2020-01-14 23:18:24 UTC
RTC time: Tue 2020-01-14 23:18:27
Time zone: America/Los_Angeles (PST, -0800)
System clock synchronized: no
NTP service: inactive
RTC in local TZ: no
xxxx@asgard:~$ sudo systemctl restart systemd-timesyncd.service
[sudo] password for xxxx:
xxxx@asgard:~$ timedatectl
Local time: Tue 2020-01-14 15:19:13 PST
Universal time: Tue 2020-01-14 23:19:13 UTC
RTC time: Tue 2020-01-14 23:19:16
Time zone: America/Los_Angeles (PST, -0800)
System clock synchronized: no
NTP service: inactive
RTC in local TZ: no
xxxx@asgard:~$ sudo timedatectl set-ntp true
xxxx@asgard:~$ timedatectl
Local time: Tue 2020-01-14 15:19:44 PST
Universal time: Tue 2020-01-14 23:19:44 UTC
RTC time: Tue 2020-01-14 23:19:47
Time zone: America/Los_Angeles (PST, -0800)
System clock synchronized: no
NTP service: inactive
RTC in local TZ: no有什么暗示吗？

此问题的发生是由于ntp.service和systemd-timesyncd.service之间的冲突。是已知的窃听器。
这一切为什么要发生？它发生在升级到19.10的系统上。ntp.service是在升级过程中结转的，而19.10's systemd-timesyncd.server不会在它出现的情况下启动。

但是，ntp仍然与各种ntp服务器进行时间同步。
可以通过卸载ntp、ntpdate和sntp并让systemd-timesyncd.service执行时间同步来解决这个问题。
