Ghi*_*reS 5 upgrade initramfs 20.04 20.10
我从 20.04 升级到 Ubuntu 20.10。然后在重新启动后显示“Initramfs 解包失败：解码失败”。
画面说：

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.
Press enter for maintainance (or press Control-D to continue):
首先确保您在 BIOS 中禁用了安全启动。
\nInitramfs 可以\xe2\x80\x99t 压缩默认格式和解码时消息错误。\n所以你需要更改为 gzip。
\n打开终端并粘贴：
\nsudo gedit /etc/initramfs-tools/initramfs.conf
\n之后找到COMPRESS=lz4，修改为COMPRESS=gzip
\n当\xe2\x80\x99s完成后，单击右上角的“保存”并关闭该文件。
\n最后粘贴到终端：
\nsudo update-initramfs -u
\n重启
\n...但是，您处于紧急模式的错误更为重要。你的 etc/fstab 是错误的，每次启动时检查磁盘都会浪费时间。\n而且你的几个驱动程序\xe2\x80\x99 似乎不能很好地识别。
