问题：Ubuntu 22.04 服务器安装程序在选择磁盘之前不断崩溃。崩溃报告显示 block_probe_fail
背景：我正在尝试在 Dell R710 上安装 ubuntu 22.04 Server。我之前在这台机器上安装了 Debian，但我用刷新到 IT 模式的 Dell PERC H310 替换了默认 RAID 控制器，这样我就可以将磁盘直接传递给操作系统。如果这很重要，我必须使用不同的 PCIe 插槽，因为新的 RAID 控制器不适合旧的 RAID 控制器的位置（而且如果 R710 检测到该插槽中的卡与原来的卡不同，它将无法启动）。但是，BIOS 可以正常看到我连接的每个磁盘。
到目前为止，我尝试在 BIOS 和 UEFI 模式下安装 22.04，结果相同。安装程序始终正确启动并引导我完成选择。我下载最新的安装程序，选择我的键盘布局、代理、镜像等，镜像完成后，安装程序立即崩溃。有时它会完全崩溃，有时它会允许我继续设置我的分区（它确实会显示我的所有磁盘）。但是，如果我继续操作，安装程序就会完全崩溃，我必须重新启动。
我也尝试过拔掉我的以太网连接并禁用我的 NIC 只是为了排除它们，但无济于事。
任何帮助我了解根本问题的帮助都将不胜感激。我有一种感觉，在我刷新 RAID 控制器并将 SAS 地址恢复为原来的状态后，其他一些设置不正确。崩溃报告的相关部分内容如下：

答案1
这个错误probert可能是你的问题：如果系统上存在非活动 raid，则探测器会失败（并停止安装）。
11 月份提交的补丁可能修复了该错误。希望 22.04.2 发布时会包含该补丁。
或者每日构建似乎包含补丁http://cdimage.ubuntu.com/cdimage/ubuntu-server/jammy/daily-live/pending/。
或者您可能只需在安装之前擦除磁盘和旧的 RAID 配置即可。
答案2
截至 2023-12-01，我在 Ubuntu Server 22.4 LTS 上遇到了同样的崩溃。
关于问题的描述...安装程序崩溃时，它不会显示任何有关块设备的信息（它会停留在与读取镜像包相关的页面上）。这一点很重要，因为人们不一定知道正在探测块设备——他们会在屏幕上看到“正在读取包”。
我修复了这个问题（根据 Andrew 的回答），通过完全擦除 Ubuntu 安装目标 SATA 驱动器的内容（在不同的 Linux 机器上使用 gparted）并重新运行安装程序。
答案3
我也遇到了同样的错误，镜像检查后安装程序崩溃。
清洁磁盘后，它可以正常工作。
sgdisk --zap-all $DISK
dd if=/dev/zero of=$DISK count=100 bs=1024
笔记：要清理磁盘，您只需切换到不同的 tty，方法是按下ALT+F2安装主机上的
