国内机器Debian9升级Debian12操作步骤-文档中心-青果网络

1.设置软件源

cat > /etc/apt/sources.list<<EOF
    deb http://archive.debian.org/debian/ stretch main contrib non-free
    deb-src http://archive.debian.org/debian/ stretch main contrib non-free
    deb http://archive.debian.org/debian-security/ stretch/updates main contrib non-free
    deb-src http://archive.debian.org/debian-security/ stretch/updates main contrib non-free
    deb http://archive.debian.org/debian/ stretch-backports main contrib non-free
    EOF

2.升级Debian 9 现有的软件包

apt update && apt upgrade -y

3.提示GPG证书问题，`NO_PUBLICKEY`

记录PUBULICKEY

`NO_PUBKEY 648ACFD622F3D138 NO_PUBKEY 0E98404D386FA1D9`

3.1安装需要的依赖和软件

apt-get install software-properties-common dirmngr -y

3.2添加gpg证书验证

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <PUBKEY>
    <PUBKEY2>
    apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 648ACFD622F3D138 0E98404D386FA1D9

4.更换debian12的软件源

cat >/etc/apt/sources.list<<EOF
    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://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware
    deb-src https://security.debian.org/debian-security bookworm-security main contrib non-free non-free-firmware
    EOF

添加公钥

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 54404762BBB6E853 BDE6D2B9216EC7A8
