我似乎对 policy-kit 有疑问。输出systemctl status --full --lines=100 polkit.service是

特别是，有一行写着Failed with result 'core-dump'。如何获取此核心转储？
我在使用 Ubuntu 22.04.1 LTS，coredumpctl目前尚未安装。
注意：我找到了一个文件/var/crash/_usr_libexec_polkitd.0.crash，但其内容无法被人类阅读。
解决方案：运行后，sudo apt install systemd-coredump我可以通过运行查看 coredumpsudo coredumpctl dump --output=/path/to/file
