我尝试安装 18.04 LTS 很多次，但每次都显示检测文件系统需要一个多小时。然后我重新开始安装。

当我启动 Live CD 时出现错误消息
[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x22 (or later)
推荐的版本号（0x22）可能不同，我记不清了。
我的安装是否因为这个错误而卡住了？
并且有一个针对此错误消息的解决方案[固件错误]：由于勘误表，TSC_DEADLINE 被禁用 - 我该怎么办？他们建议在哪里使用sudo apt-get install intel-microcode。我应该将其安装在 liev CD 中吗？
答案1
这个问题已经存在好几年了。它是由set -e顶部的引起的/bin/partman-commit。当卸载步骤失败时（因为有一个文件系统托管着正在访问安装介质的循环设备，并且该设备正在使用中），它会partman-commit立即退出。它永远不会执行 中的任何其他操作/lib/partman/commit.d，也不会向 ubiquity（安装程序）发出信号（它的最后一步）。因此 ubiquity 永远挂起。
解决方法：
编辑/bin/partman-commit并更改set -e为set -x
