升级到 18.04 后未找到“linux-generic-hwe-18.04”

自从从 16.04 升级到 18.04 以来，我一直看到以下消息：

➜  ~ hwe-support-status 

You have packages from the Hardware Enablement Stack (HWE) installed that
are going out of support on 2023-04-30.

To upgrade to a supported (or longer-supported) configuration:

* Upgrade from Ubuntu 16.04 LTS to Ubuntu 18.04 LTS by running:
sudo do-release-upgrade -p

OR

* Switch to the current security-supported stack by running:
sudo apt-get install linux-generic-hwe-18.04

and reboot your system.

有人知道为什么会发生这种情况吗？

答案1

18.04 尚不需要特定的 hwe 或 lts linux-image（因此不存在）。首先确保已安装 linux-image-generic 映像：

 apt install linux-image-generic

然后删除旧的 hwe 或 lts linux 映像，就我而言，我这样做了：

apt purge linux-image-generic-lts-xenial

然后hwe-support-status命令返回一个干净的空响应。

答案2

我安装了一个旧的不受支持的 Linux 内核，发现使用

# apt 策略 linux-generic\*

记得跑

# apt 自动删除
删除任何未使用的依赖项，这些依赖项也可能被 hwe-support-status 拾取。
