我正在尝试安装 VPN 客户端（圣天诺 dVPN）在 Linux Mint 18.2 上.deb
包管理器返回：
"Error: Dependency is not satisfiable: shadowsocks-libev"
sudo apt-get install shadowsocks-libev回
E: Unable to locate package shadowsocks-libev"
并sudo snap install shadowsocks-libev有效，但依赖性错误仍然存在。
这是我安装的第一个依赖项snap，所以以这种方式安装时可能会遇到识别它们的问题？
我怎样才能找出问题出在哪里？
到目前为止，我还没有找到解决方案，但我只剩下一个未满足的依赖项，请参阅：edit2。
编辑：似乎我遇到了运行中未满足的依赖项的下一堵墙
sudo sh -c 'printf "deb http://deb.debian.org/debian stretch-backports main" > /etc/apt/sources.list.d/stretch-backports.list'
sudo apt update`

我已经安装了 libc-ares21.10.0-3ubuntu0.2，但它无法识别它......如果我修复这个问题，它应该可以工作
有任何想法吗？
答案1
Mint 基于 debian 9，因此您可以使用以下命令安装必要的软件包
sudo sh -c 'printf "deb http://deb.debian.org/debian stretch-backports main" > /etc/apt/sources.list.d/stretch-backports.list'
sudo apt update
sudo apt -t stretch-backports install shadowsocks-libev
Snap 安装无法解决您需要使用 apt 安装的 apt 依赖性问题
