解决方法
参考了这篇文章： Linux常见问题三则：systemd-udev-settle.service: Executable path is not absolute, ignoring: udevadm settle
先打开这个文件:
sudo vim /lib/systemd/system/systemd-udevd.service
输入“/”进行搜索，搜索内容为报错的关键信息：“/lib/systemed/systemd-udevd”
在这一行的下面，是可执行文件udevadm的路径，此处替换为该文件的真实路径即可，如果不知道路径， 可以用sudo find / -name "udevadm"查找。
