E: Some index files failed to download. They have been ignored, or old ones used instead.

我已尝试过，sudo rm -rf /var/lib/apt/lists/*但问题仍然存在。

答案1

就我而言，我必须将 Ubuntu 软件更新服务器从巴西更改为美国，然后运行：

$ apt-get clean
$ apt-get update

这确实有效。

答案2

发生这种情况的原因是并非所有镜像都会同时更新。出于各种原因，更新会按计划推出，并且可能需要几天时间才能使所有镜像同步。

如果你遇到这个问题，最好的解决办法就是小睡一会儿或等到第二天。如果你想确认，或者看看你的镜像何时更新，你实际上可以看这里。这将向您显示镜像的状态，包括它们在同步过程中可能落后多少。

您还可以将镜像更改为新的，如果您要更新以修复的是一个重大安全问题，这可能是一个好主意。

如果您决定更改镜像，请从“首选项”中打开“软件和更新”，第一个选项卡上有一个下拉菜单，标有“下载自：”，然后选择备选镜像。如果您感兴趣，通常认为最佳做法是选择地质上离您最近的镜像。

答案3

apt-get clean 成功了！感谢大家的帮助。

答案4

apt-get clean对我来说没用。在这里找到了解决方案： https://askubuntu.com/a/1229971

“打开软件和更新并更改下载自到主服务器“
