18.04安装卡在检测文件系统中
我尝试了很多时间安装18.04 LTS，但是所有时间都显示检测文件系统需要一个多小时。 然后我重新启动安装。

[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x22 (or later)
建议的版本号（ 0x22 ）可能不同，我不记得了。
我的安装是否因此错误而停滞不前？
[固件错误]中存在此错误消息的解决方案：由于勘误而禁用TSC_DEADLINE – 我该怎么办？ 他们建议使用sudo apt-get install intel-microcode 。 我应该在liev CD中安装吗？
多年来这一直是个问题。 它是由/bin/partman-commit顶部的set -e引起的。 当卸载步骤失败时（因为有一个文件系统托管正在访问正在使用的安装介质的循环设备）， partman-commit立即退出。 它永远不会在/lib/partman/commit.d执行任何其他/lib/partman/commit.d ，它永远不会发出无处不在的信号，安装程序（它的最后一步）。 所以无处不在永远存在。
解决方法：
编辑/bin/partman-commit并将set -e更改为set -x
