我刚刚将 LTS 升级到最新版本 (20.04 -> 22.04),重启时失败。即使使用之前的内核,即使在救援模式下,也会以同样的方式失败。
我很久以前遇到过类似的问题,涉及从 LiveUSB 启动并执行 chroot……但有人可以给我一些指点,告诉我该尝试什么吗?
复杂情况:该分区已加密......(它没有到达要求输入密码的步骤)
屏幕上显示的最后一条消息是(略微简化):
VFS: Cannot open root device "mapper/kubuntu--vg-root" or unknown block(0,0) error -6
Please append a correct "root=" boot option; here are the available partitions:
