为什么“~$ sudo openvpn ~/<file_name>.ovpn”会报错？
Why does "~$ sudo openvpn ~/<file_name>.ovpn" give error?
几周前我得到了一份 .ovpn 工作文件，起初，一切正常，运行 没问题。当我再次尝试使用它时，出现了这个错误
<user>@<name>:~$ sudo openvpn ~/<file_name>.ovpn
Options error: In [CMD-LINE]:1: Error opening configuration file:
/home/<name>/<file_name>.ovpn
Use --help for more information.
所以我尝试了 openvpn --config <file_name>.ovpn 并得到了这个
<user>@<name>:~$ openvpn --config <file_name>.ovpn

我该怎么做才能解决这个问题？提前致谢。
我能够使用添加到上一个命令的 --auth-retry 和 interact 修复它：
<user>@<name>:~$ sudo openvpn --config <file_name>.ovpn --auth-retry interact
