我有一台戴尔笔记本电脑，出厂时安装了 Ubuntu，在撰写本文时，我正在使用Ubuntu 18.04.6 LTS。从过去的两天开始，当我重新启动笔记本电脑时，突然需要相当长的时间才能启动，然后进入紧急模式。在紧急模式屏幕上，当我点击Enter用户root提示符时，会出现提示符，当我输入exit 幸运的是我可以看到登录屏幕并可以进入系统并开始使用它。
我探索了与此问题相关的各种资源，其中大多数都说这种情况发生在文件系统损坏或由双重启动或创建新分区或存在问题时/etc/fstab。双重启动和新分区创建绝对不适用于我的情况。如果文件系统损坏，很抱歉，我不知道如何诊断它。如果存在问题，/etc/fstab那么我已经多年没有碰过它了。
我检查journalctl -xb并提取了在网络上找到的大多数相关资源中引用的日志。下面是带有不同 grep 术语的输出。由于该命令的输出很长，我认为将其全部发布在这里没有用。另外，我不知道如何从紧急模式终端本身获取整个输出，以便我可以将其以代码格式粘贴到这里，因为我不是使用终端的专家。我能想到的唯一方法是使用我的手机相机拍摄屏幕照片。考虑到这一点，我希望下面提供的内容能够帮助任何能帮助我解决此事的人。如果需要更多信息，请告诉我，我会尽力提供。
