apt升级失败:未满足的依赖关系

Question

我有一个Ubuntu20.04服务器。最近我试图更新它。我遇到了这个错误

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

我照它说的做了，但没有帮助

$ sudo apt --fix-broken install

我尝试了我找到的解决办法，但没有结果。

$ sudo dpkg --configure -a
$ sudo apt upgrade

重启也于事无补。如果有人能帮上忙，或者知道是什么造成了这个问题，我将非常感激。这台服务器对我来说有点重要。DNS，文件共享，电影，所有那些有趣的东西都会从里面跑出来。提前谢谢。

Removing systemd-timesyncd (245.4-4ubuntu3.3) ...

日志不包含结束。下一个日志17天后开始。还有IDK为什么要删除systemd-timesyncd。

更新:我尝试重新安装systemd-timesyncd并得到了这个错误systemd-timesyncd is already the newest version (245.4-4ubuntu3.3).，它表示无论我是apt install还是apt --fix-broken install。

Answer 1

原来我的sudo apt reinstall systemd-timesyncd太大了。现在修好了。
