我最近安裝了 Debian 11 並開始亂搞，以至於我找不到任何帶有apt.例如，當我運行時sudo apt install ifconfig它返回：E: Unable to locate package ifconfig。我已經讀了十幾頁，它可能需要對我的sources.list文件做一些事情。
我檢查了文件，對我來說一切都很好。內容sources.list：
deb http://deb.debian.org/debian bullseye main contrib non-free
deb-src http://deb.debian.org/debian bullseye main contrib non-free
deb http://deb.debian.org/debian-security/ bullseye-security main contrib non-f>
deb-src http://deb.debian.org/debian-security/ bullseye-security main contrib n>
deb http://deb.debian.org/debian bullseye-updates main contrib non-free
deb-src http://deb.debian.org/debian bullseye-updates main contrib non-free
#buster-backports
deb http://deb.debian.org/debian buster-backports main contrib non-free
deb http://archive.debian.org/debian stretch main contrib non-free
有人知道什麼可以解決這個問題？

你sources.list看起來不錯*，apt update工作，apt search工作。
sudo apt install ifconfig返回的原因E: Unable to locate package ifconfig是沒有名為 的包ifconfig。
請閱讀如何找出哪個套件擁有某個檔案？名為的可執行文件ifconfig 位於名為net-tools。這應該有效並給你ifconfig：
sudo apt install net-tools
注意確實apt search ifconfig在其他幾個包中找到了這個包。您聲稱「找不到任何包含apt」的軟體包似乎沒有道理。
* 除了這些non-f>，我假設是發布（或另一個文字編輯器）在截斷行時打印n>的結果，而不是發布實際的結果nano sources.list滿的內容sources.list。
