所以我刚刚对 Linux Mint 20 进行了全新安装，但这个问题在 Linux Mint 19.3 中也存在。每次我尝试从软件管理器执行apt-get update或apt-get upgrade什至下载软件时，都会出现错误。当我尝试更新更新管理器推荐的内容时，发生了同样的事情。

我发现如果我sudo apt-get update/upgrade在每次失败的尝试后继续运行该命令，我可以升级或更新。由于每次更新/升级都以一定的百分比停止，当我再次运行该命令时，它会从相同的百分比继续，并通过执行几次更新/升级最终完成。

这是我尝试从软件管理器下载 VLC 时遇到的错误。它首先说：

Failed to download package files
Check your Internet connection.

...等等。

error 随处可见的两个具体误差值是2001:67c:1360:8001::23和91.189.88.152。我的机器现在使用的软件源是：

(Main) http://packages.linuxmint.com
(Focal) http://archive.ubuntu.com/ubuntu

我尝试将焦点源更改为许多不同的源，但没有成功。我什至搞乱了之前source.list的文件/etc/apt/source.list.d，并且由于许多问题而不得不重新安装 Linux。所以我真的不知道在这里该怎么办，并且发现很多其他人也有同样的问题。

答案1

这看起来像是 IPv6 堆栈配置错误。 Linux 认为它有 IPv6 并尝试使用它（实际上更喜欢它）进行连接。

您可以强制apt-get使用 IPv4 添加-o Acquire::ForceIPv4=true。例如：

$ sudo apt-get -o Acquire::ForceIPv4=true update

如果您想让该选项永久存在，您可以将其添加到 中的文件中/etc/apt/apt.conf.d/，例如内部/etc/apt/apt.conf.d/99only-ipv4：

Acquire::ForceIPv4 "true";
