sudo：pam_open_session：模块未知 sudo：策略插件会话初始化失败

我可以使用pkexec命令，但是sudo没有运行。谁能帮我吗？

我的pam.config文件看起来像

# ---------------------------------------------------------------------------#
# /etc/pam.conf                                  #
# ---------------------------------------------------------------------------#
#
# NOTE
# ----
#
# NOTE: Most program use a file under the /etc/pam.d/ directory to setup their
# PAM service modules. This file is used only if that directory does not exist.
# ---------------------------------------------------------------------------#

# Format:
# serv. module     ctrl       module [path] ...[args..]          #
# name  type       flag                              #

我的pam.d / sudo文件看起来像
