我想在Debian 8服务器上运行https://stackoverflow.com/a/29398380/2724978。
我已安装所有依赖项，并使用
进行sshssh -Y user@domain.com
但是，当我运行该代码时，我收到错误：
> Traceback (most recent call last): File

> raise RuntimeError('Attempted to use a closed Session.') RuntimeError: Attempted to use a closed Session.
请注意，此代码会创建新的GUI窗口
当我原生运行时（没有ssh，通过物理登录gnome环境） 运行得很好。（我能看到那些窗户）
编辑：
我不知道发生了什么，但现在它显示更多错误：
