RETURN VALUE
Upon successful completion, the return value is the return value of PROGRAM. If the
calling process is not authorized or an authorization could not be obtained through
authentication or an error occured, pkexec exits with a return value of 127. If the
authorization could not be obtained because the user dismissed the authentication
dialog, pkexec exits with a return value of 126.

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
