无法将时间同步到 Ubuntu 19.10 上的网络服务器

三周前升级到 19.10，从那时起，我无法让系统与时间服务器同步。

我做了什么：

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

有什么提示吗？

答案1

ntp.service该问题是由于和之间存在冲突而导致的systemd-timesyncd.service。这是一个已知错误。

为什么会发生这种情况？它发生在已升级到 19.10 的系统上。ntp.service在升级过程中会被延续，并且 19.10systemd-timesyncd.server不会在其存在的情况下启动。

请参阅以下内容：

这个问题的一个视觉副作用可以在Date & Time设置面板中看到。您无法启用“自动日期和时间”。开关切换回禁用状态。

在此处输入图片描述

但是，ntp仍然与各个 ntp 服务器进行时间同步。

这能ntp可以通过卸载、ntpdate和sntp并执行systemd-timesyncd.service时间同步来修复。
