在 Ubuntu Focal 20.04 上禁用 HWE 内核支持

我不知道如何或为什么，但我已经安装了 HWE。至少，apt声称有一个更新：

# apt list --upgradable -a
Listing... Done
linux-headers-generic-hwe-20.04/focal-updates,focal-security 5.13.0.28.31~20.04.15 amd64 [upgradable from: 5.11.0.46.51~20.04.23]
linux-headers-generic-hwe-20.04/now 5.11.0.46.51~20.04.23 amd64 [installed,upgradable to: 5.13.0.28.31~20.04.15]
linux-headers-generic-hwe-20.04/focal 5.4.0.26.32 amd64

但是现在使用的内核似乎是一个已发布的版本：

# uname -ar
Linux host1 5.4.0-91-generic #102-Ubuntu SMP Fri Nov 5 16:31:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

我尝试删除 HWE 包，但它似乎在 20.04 上安装了 18.04 版本...？由于这似乎不对，我停止了该过程：

# apt remove linux-headers-generic-hwe-20.04

The following packages were automatically installed and are no longer required:

Use 'apt autoremove' to remove them.
The following additional packages will be installed:
  linux-headers-generic-hwe-18.04
The following packages will be REMOVED:
  linux-headers-generic-hwe-20.04
The following NEW packages will be installed:

After this operation, 0 B of additional disk space will be used.

Abort.

这里出了什么问题？我只想坚持使用 5.4.0-xx 版本，而不在此系统上使用任何 HWE 版本。

答案1

1 - 安装linux-generic

linux-generic:
  Installed: (none)
  Candidate: 5.4.0.99.103
  Version table:
     5.4.0.99.103 500
        500 [redacted]/mirror/us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
        500 [redacted]/mirror/us.archive.ubuntu.com/ubuntu focal-security/main amd64 Packages
     5.4.0.26.32 500
        500 [redacted]/mirror/us.archive.ubuntu.com/ubuntu focal/main amd64 Packages

2 - 重新启动，进入 GRUB 菜单，并启动到 linux-generic 内核

3 - 删除所有其他的linux-generic-*, linux-headers-*等等

基本上，你希望实现与提出这个问题的人相反的结果：如何阻止带有 HWE 内核的 16.04.2 更新至 4.4 内核
