背景
离线环境中节点安装的操作系统为Ubuntu-22.04，该离线环境无法直通公网，但是在本地可以通过ssh连接节点。 因此可以通过 scp 复制 deb 包到离线节点的方式来安装应用。
执行步骤
下载安装包
sudo apt-get download percona-xtrabackup-80
安装包
ubuntu@ubuntu:~$ sudo dpkg -i percona-xtrabackup-80_8.0.32-26-1.jammy_amd64.deb
Selecting previously unselected package percona-xtrabackup-80.

若无报错则安装完成
若提示依赖错误，则按照提示继续下载依赖包。如上面的运行结果中缺失libdbd-mysql-perl，libcurl4-openssl-dev，libev4三个依赖包。
sudo apt-get download libdbd-mysql-perl
sudo apt-get download libcurl4-openssl-dev
sudo apt-get download libev4
# 使用sudo dpgk -i xxxxx命令安装下载的依赖包
若存在递归的依赖，则继续下载依赖包即可。
把所有的deb包通过scp传到离线环境中，并直接使用dpkg命令安装即可。
PS
可以使用以下命令来查看xxxx依赖的deb包
sudo apt-cache depends xxxx
如果只想显示必须的软件包，可以使用：
sudo apt-cache depends sshpass | grep Depends | cut -d ":" -f 2-
