    情景：
    命令行提示执行apt autoremove;
    然后没认真看就执行了，依稀记得有dde;
    然后界面点击软件无法打开，估计dde已卸载;
    重启出现如题问题，无法进入系统。
    措施：
    进入Deepin Recovery恢复系统；
    原本想重新安装dde，发现插网线都无法上网；
    然后搜查关键词，发现恢复系统的lightdm无任何问题；
    检查lightdm的日志也没有问题，貌似不能看到出问题时的日志；
    重启停在问题界面，Ctrl+Alt+F2，切换tty后只是出现光标在闪，无法输入命令。
    问题：
    如何修复系统？
    如何使得Deepin Recovery可以联网？

    在Grub菜单里面，进入高级选项（第二行），选择recovery（第二行），进入后用手机通过USB分享网络给电脑，如果你的有线网络可以直接用也可以试一下。然后输入ROOT密码进去控制台。执行apt install dde，然后输入reboot试试

    我感觉在恢复系统中安装软件都是装在恢复系统，根本影响不了原本的系统

    我这种局外人就不折腾了，谢谢各位回帖。
    解决方法：重装，保持原有分区策略，家目录数据保留，然后更新系统至15.7。重装耗时30mins，更新系统耗时90mins。

    就一个15.5的USB安装盘，没别的电脑，这样直接来得快。

    我最后也是通过重装系统解决的，既然把autoremve删除了很多软件，那还是重装来的干净些
