我的问题与以下问题类似（即使不完全相同）Ubuntu 20.04，每次启动都会进行非常长的文件系统检查声誉不足以评论加入俱乐部。
使用 grub 引导加载程序在配备 HP SSD 的笔记本电脑上双启动 Linux/Windows 系统。与 19.04 完美配合。发布后不久就升级到了 20.04。在 grub 屏幕后的第二次（？？）重新启动时，包含旋转器的文件系统检查消息不断出现。此外，承诺的“Ctrl-C”中断根本不起作用。
然后我重新安装了 19.04，它又能正常工作了。今天到达 19.04 的支持终止点，我以为 20.04 可能会有所改进，但无济于事！旋转器又无休止地转动 »Ctrl-C«，一点帮助都没有。
奇怪的是，升级到 20.04 后第一次重启就成功了：我看到文件系统检查消息在五秒钟后消失，正如预期的那样，然后成功继续重启过程。但第二次重启时我又卡住了。
我采用了GRUB_CMDLINE_LINUX_DEFAULT="fsck.mode=skip ..."解决方法，但显然建议在启动时进行文件系统检查。
My/etc/fstab包含四个条目，分别对应于、/和swap：/boot/efi/home

使用实时启动系统fsck /dev/nvme0n1p6和fsck /dev/nvme0n1p7执行几乎立即报告两个“干净”的文件系统。强制文件系统检查会为分区产生可纠正的警告/home：
