我有一台 Ubuntu 20.04 服务器。最近我尝试更新它。我遇到了这个错误

重启也没用。如果有人能帮忙或者知道是什么原因导致这个问题，我会非常感激。这个服务器对我来说很重要。DNS、文件共享、电影，所有这些有趣的东西都运行在它上面。提前谢谢。

Removing systemd-timesyncd (245.4-4ubuntu3.3) ...
日志没有结束。下一个日志将在 17 天后开始。另外我不知道它为什么试图删除 systemd-timesyncd...
更新：我尝试重新安装 systemd-timesyncd 并收到此错误，
systemd-timesyncd is already the newest version (245.4-4ubuntu3.3).
它表明无论我apt install还是apt --fix-broken install
答案1
事实证明我也遇到过这种情况sudo apt reinstall systemd-timesyncd。现已修复。
