Ubuntu 20.04 服务器安装在分区期间失败 - SUBIQUITY FAILURE

Ubuntu 20.04 服务器安装在分区期间失败 - SUBIQUITY FAILURE

SUBIQUITY 失败。(我无法创建新标签 - 因此我只能在这里大声喊叫,抱歉)

我正在将我的服务器从 Ubuntu 18.04.4 LTS“桌面”映像升级到 20.04 LTS 服务器。

/dev/sda1 (ext4) 上的 /boot / /dev/sda3 (ext4) ZFS 池上的用户数据。

在完成选择现有分区并提交的过程后,subiquity 安装程序在创建 /dev/sda1 时始终失败。

重新使用(并重新格式化)现有分区,这不是一个不常见的情况吗?

我尝试保存此日志(并将三次尝试的所有日志提交给 Canonical),但在 USB 上找不到它们,也没有 casper-rw 文件(尽管设置了 4GB 的持久存储)。因此,提供数据来解决问题确实很困难。

幸运的是,我有根分区和启动分区的备份,所以我会将它们放回原位以使系统再次运行。

更新:重新添加root和boot,系统再次运行18.04.4。

答案1

从虚拟机配置中禁用网络,安装程序不会崩溃。安装 ubuntu 后,重新启用网络并照常配置

答案2

这看起来像https://bugs.launchpad.net/ubuntu/+source/subiquity/+bug/1875560该问题已在 20.05.1 版本中修复,现在应将其作为安装的一部分提供给您。
