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
