帮我执行个 Linux 命令，看看兼容性

[opentrade]

分别是提权和取消提权后的结果，并请告知发行版本和桌面环境，谢谢了，拜托

我遇到了跟这个问题完全一致的现象：

https://askubuntu.com/questions/799669/etc-sudoers-file-corrupted-and-i-cant-run-pkexec-visudo-over-ssh

在单会话 SSH 中 auth 失败。
但 systemctl 这样的提权命令又是能成功通过验证的


sudo pkexec 正常

支持楼主开发桌面 app.

可以 ps -ef 检查有没有 polkit 进程来接收请求, 没有就返回 127, 有就是 0.

不同桌面环境进程名不一样, xfce 和 i3 桌面环境是 /usr/lib/xfce-polkit/xfce-polkit
