今天小編在制作鏡像時發現竟然安裝不了基本的linux命令，例如ps等，報類似以下的錯誤
libncurses6 : Depends: libtinfo6 (= 6.2+20201114-2+deb11u1) but 6.4-4 is to be installed
重新安裝libtinfo6的指令也沒用
apt-get --reinstall install libtinfo6 Reinstallation of libtinfo6 is not possible, it cannot be downloaded.
或者提示各種依賴錯誤

網上有說換回官方的源就ok了，這確實是一個萬能方法，可是網路實在太差呀。安裝一個包要等半天。最後一查，原來是鏡像源沒有對應正確的系統版本，版本搞錯了。
比如你用的是debian11，卻用的debian10的鏡像源，就會報這個錯誤。
修改鏡像源的方法, 編輯一下sources.list文档：
vi /etc/apt/sources.list deb https://mirrors.ustc.edu.cn/debian/ bookworm main contrib non-free non-free-firmware deb-src https://mirrors.ustc.edu.cn/debian/ bookworm main contrib non-free non-free-firmware deb https://mirrors.ustc.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware deb-src https://mirrors.ustc.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware deb https://mirrors.ustc.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware deb-src https://mirrors.ustc.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware deb https://mirrors.ustc.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware deb-src https://mirrors.ustc.edu.cn/debian-security/ bookworm-security main contrib non-free non-free-firmware
之後更新一下文档列表就可以了
apt-get update
安裝你想安裝的文档吧。
