我的内核是 5.13.0-37-generic 版本。
>uname -r
5.13.0-37-generic
我需要为它安装标题，但是当我运行时
>apt search linux-headers-$(uname -r)
什么也没找到。最接近的标头版本是
>sudo apt search linux-headers

当前 HWE 内核为5.13.0-40。您需要先更新系统。
更新存储库似乎已被禁用。运行以下命令main恢复默认设置：sources.list
sudo rm /etc/apt/sources.list
打开“软件和更新”应用程序并启用第一个选项卡上的所有存储库main。
另外，在更新选项卡中将其更改为“全部”。
然后运行
sudo apt update
sudo apt upgrade
您将获得当前内核。重新启动以运行此内核。然后您将能够通过以下方式安装标头：
sudo apt install linux-headers-5.13.0-40-generic
