腾讯轻量云无忧，在dd或者安装宝塔的时候，都会提示没有unzip的错误，需要替换掉腾讯的apt镜像源。
vim /etc/apt/sources.list自带的源如下：
deb http://mirrors.tencentyun.com/debian buster main contrib non-free
# deb-src http://mirrors.tencentyun.com/debian buster main contrib non-free
deb http://mirrors.tencentyun.com/debian buster-updates main contrib non-free
# deb-src http://mirrors.tencentyun.com/debian buster-updates main contrib non-free
deb http://mirrors.tencentyun.com/debian-security buster/updates main contrib non-free
# deb-src http://mirrors.tencentyun.com/debian-security buster/updates main contrib non-free
# deb http://mirrors.tencentyun.com/debian buster-backports main contrib non-free
# deb-src http://mirrors.tencentyun.com/debian buster-backports main contrib non-free
# deb http://mirrors.tencentyun.com/debian buster-proposed-updates main contrib non-free
# deb-src http://mirrors.tencentyun.com/debian buster-proposed-updates main contrib non-free
替换为tuna清华apt镜像源：
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free
# deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free再执行下面命令更新apt源后重新安装unzip：
