‘’linux泛型-hwe- 18.04‘升级到18.04后找不到

Question

自从从16.04升级到18.04以来，我看到了以下信息：

➜  ~ 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.

有人知道为什么会这样吗？

Answer 1

18.04还不需要特定的hwe或linux映像(所以它不存在)。首先确保安装了linux映像通用映像：

 apt install linux-image-generic

然后删除旧的hwe或lts linux映像，在我的例子中，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。
