由于部分系统差异，可能默认软件源并不能满足需求，所以需要修改软件源

服务器在国内请添加国内镜像源

演示系统：debian

修改软件源

备份原文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

编辑软件源的配置文件

sudo vim /etc/apt/sources.list

键入i进行编辑，替换为

deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware
deb http://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware
deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware

按ESC键输入:wq即可保存退出

修改docker源

添加 Docker 官方 GPG 密钥：

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg –dearmor -o /usr/share/keyrings/docker.gpg

添加 Docker 官方 APT 源：

1
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
