将 Ubuntu 20.04 更新到 22.04 时出错 - 符号链接级别太多

Question

我在升级时看到了一堆错误，所以我重新启动了。现在，如果我尝试启动最新的内核，系统就会挂起。我启动到旧内核的恢复模式并尝试删除所有 nvidia 软件包，因为我记得提到了 nvidia 的一些错误，但这似乎不起作用。

我现在可以启动5.4.0-125-generic（当前安装的最新版本是 5.15.0-46-generic），但是看起来旧包（linux-image-extra-4.4.0-47-generic）正在导致错误：

$ apt -f install

当我尝试linux-headers-4.4.0-47-generic使用 apt 安装时，我得到：

所以我从 Launchpad 下载并linux-headers-4.4.0-47安装了它们，但我仍然收到错误Too many levels of symbolic links。我也好像跑不了了update-initramfs。

Answer 1

我似乎已经修好了。

首先，我想到强制删除linux-image-extra-4.4.0-47-generic，这似乎是问题的核心。我发现了这个问题并执行了以下操作：

mv /var/lib/dpkg/info/linux-image-extra-4.4.0-47-generic.* /tmp
dpkg --remove --force-remove-reinstreq linux-image-extra-4.4.0-47-generic

然后我尝试执行apt -f install，但仍然有包创建错误：
