upower.service 无法启动 ubuntu 20.04

Question

我刚刚从 Ubuntu lxde 18.04 升级到 Ubuntu lxqt 20.04，遇到了 upower.service 无法正常启动的问题（在启动时以及当我尝试使用 启动服务时sudo service start upower）。

journalctl -xe -u upower

如果我以 root 身份手动启动守护进程：

sudo /usr/lib/upower/upowerd --verbose &

它工作正常。

然后我就可以启动xfce4-power-manager或lxqt-powermanagement以非root身份启动。

我没有改变服务的定义方式：

文件 ：/lib/systemd/system/upower.service

我的 Ubuntu 内核版本：

uname - a

4.15.0-96-generic #97-Ubuntu SMP Wed Apr 1 03:25:46 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

编辑（感谢@David，我意识到更新过程中一定出了问题，我确实sudo apt install --install-recommends linux-generic-hwe-20.04这样做sudo grub-set-default 0了sudo update-grub），现在我正在运行最新的内核，但它仍然不起作用。：

uname - a

Linux  5.13.0-39-generic #44~20.04.1-Ubuntu SMP Thu Mar 24 16:43:35
UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

您能否就如何让 upower 作为服务正确启动提供建议？谢谢
