archlinux+dde Failed to start Light Display Manager.(虚拟机)

虚拟机安装archlinux+dde,前两天因为更新了python3.10.1导致开机黑屏,今天更新了一下发现lightdm又不能启动了。

哇,大佬啊:lol:

我是虚拟机装了个基础Arch,后面的桌面环境安装都是克隆基础镜像然后再安装的,结果克隆了太多次,把xorg和xorg-server都忘了装了

不过又回到之前的那个问题了,开机黑屏。了解点,但是不知道怎么构建

死马当活马医,实在是没办法了,都试一下。因为更新前确实是可以用的,更新完了以后就出现开机黑屏这种情况了。

我的机器正常更新也有同样问题,再次更新时先忽略所有的python包就好了,等下次再升级python
