“sudo apt update”下載包失敗

嘗試sudo apt update在我的伺服器上執行時出現以下錯誤：

Debian 版本：

No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 8.11 (jessie)
Release:        8.11
Codename:       jessie

到目前為止我已經嘗試過：

• 進入unset http_proxy並unset https_proxy在控制台中
• 更改/etc/apt/sources.list為以下內容：

deb http://debian.uberglobalmirror.com/debian/ stretch main
deb-src http://debian.uberglobalmirror.com/debian/ stretch main

deb http://security.debian.org/ stretch/updates main contrib
deb-src http://security.debian.org/ stretch/updates main contrib

# stretch-updates, previously known as 'volatile'
deb http://debian.uberglobalmirror.com/debian/ stretch-updates main contrib
deb-src http://debian.uberglobalmirror.com/debian/ stretch-updates main contrib

• 以下命令來自此處：

sudo cp /etc/apt/sources.list ~/ 
sudo wget "http://pastebin.com/raw.php?i=uzhrtg5M" -O /etc/apt/sources.list 
sudo apt-get update
sudo rm /etc/apt/sources.list.d/ubuntu-extras.list
sudo apt-get update

• sudo apt-get upgrade``sudo apt-get upgrade -f從這裡開始。
• apt-get clean

我已經閱讀了很多文章，但沒有一個提到的解決方案對我有用。任何幫助，將不勝感激

這裡有很多問題。

• Jessie 自 2020 年 6 月以來一直不受支持，因此您需要刪除對它的所有引用，因為它不會再出現在包儲存庫中
• Stretch 可用，但僅在 LTS 中可用，直到 2022 年 6 月
• 巴斯特是目前的“穩定”
• 你得到Temporary failure resolving 'debian.uberglobalmirror.com'. 它不再是儲存庫伺服器，所以我建議你用推薦的條目替換它，實際上你的整個sources.list集合，如果你必須替換，buster``stretch

 deb http://deb.debian.org/debian buster main contrib non-free
 deb-src http://deb.debian.org/debian buster main contrib non-free

 deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free
 deb-src http://deb.debian.org/debian-security/ buster/updates main contrib non-free

 deb http://deb.debian.org/debian buster-updates main contrib non-free
 deb-src http://deb.debian.org/debian buster-updates main contrib non-free

• 您可能需要安裝更新的包簽名密鑰
• 您最好重新安裝“buster”；嘗試從不再存在於儲存庫中的發布版本進行升級並不有趣（去過那裡……）
