無法啟動與 archive.ubuntu.com:80 (2001:67c:1360:8001::24) 的連接，網路無法存取) [IP: 91.189.88.142 80

所以我剛剛對 Linux Mint 20 進行了全新安裝，但這個問題在 Linux Mint 19.3 中也存在。每次我嘗試從軟體管理器執行apt-get update或apt-get upgrade甚至下載軟體時，都會出現錯誤。當我嘗試更新更新管理器推薦的內容時，發生了同樣的事情。

我發現如果我sudo apt-get update/upgrade在每次失敗的嘗試後繼續運行該命令，我可以升級或更新。由於每次更新/升級都以一定的百分比停止，當我再次運行該命令時，它會從相同的百分比繼續，並通過執行幾次更新/升級最終完成。

這是我嘗試從軟體管理員下載 VLC 時遇到的錯誤。它首先說：

Failed to download package files
Check your Internet connection.

....等等。

error 隨處可見的兩個特定誤差值是2001:67c:1360:8001::23和91.189.88.152。我的機器現在使用的軟體來源是：

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

我嘗試將焦點來源更改為許多不同的來源，但沒有成功。我什至搞亂了之前source.list的文件/etc/apt/source.list.d，並且由於許多問題而不得不重新安裝 Linux。所以我真的不知道在這裡該怎麼辦，並且發現許多其他人也有同樣的問題。

答案1

這看起來像是 IPv6 堆疊配置錯誤。 Linux 認為它有 IPv6 並嘗試使用它（實際上更喜歡它）進行連接。

您可以強制apt-get使用 IPv4 新增-o Acquire::ForceIPv4=true。例如：

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

如果您想要讓該選項永久存在，您可以將其新增至 中的檔案中/etc/apt/apt.conf.d/，例如內部/etc/apt/apt.conf.d/99only-ipv4：

Acquire::ForceIPv4 "true";
