我从 20.04 升级到 Ubuntu 20.10。然后重启后显示“Initramfs 解压失败：解码失败”。
屏幕上显示：

you are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or "exit" to boot into default mode.

答案1
首先确保您在 BIOS 中禁用了安全启动。
Initramfs 无法压缩默认格式，解码时会显示错误信息。因此需要改用 gzip。
打开终端并粘贴：
sudo gedit /etc/initramfs-tools/initramfs.conf
之后找到COMPRESS=lz4并将其更改为COMPRESS=gzip
完成后，单击右上角的保存并关闭此文件。
最后只需粘贴到终端：
sudo 更新-initramfs -u
重启
... 但是，您处于紧急模式的错误更为重要。您的 etc/fstab 是错误的，每次启动时检查磁盘都会浪费时间。另外，似乎您的几个驱动程序无法很好地识别。
