内核是5.19.0-38-泛型，但apt安装linux-headers泛型表示linux泛型已经是最新版本(5.15.0.58.56)

Question

我不知道最近安装的22.04是如何陷入这种混乱的，但假设我在上周添加了一个存储库来获取一些东西，因为我显然是要引导到一个5.19.0-38内核，但是它的内核头却不存在。(我之所以知道，是因为VirtualBox停止了工作，并且明显地抱怨vboxdrv模块不存在。)/sbin/vboconfig的输出是：

This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
    linux-headers-generic linux-headers-5.19.0-38-generic

    linux-headers-generic linux-headers-5.19.0-38-generic

但是apt-get install linux-headers-generic linux-headers-5.19.0-38-generic (作为根和apt update之后)说：

root@Clevo2:/home/chris# apt-get install linux-headers-generic linux-headers-5.19.0-38-generic
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package linux-headers-5.19.0-38-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'linux-headers-5.19.0-38-generic' has no installation candidate

我怀疑我的grub设置可能是问题所在。update-grub给了我以下内容：

root@Clevo2:/home/chris# update-grub

虽然我宁愿先看看我在这里得到了什么建议，但自从运行这台机器之后，我还没有重新启动过它。有人能看到前进的路吗？我非常需要virtualbox (遗憾的是，为了能够再次使用M$oft Wurd:道歉！)

我想这意味着需要更新。

我怀疑这可能不是一个在所有机器上都能工作的答案，但它在我的工作开始的地方起了作用。它来自Laptopswithlinux的彼得·庞特，他提供了这台机器：

打开终端并运行: sudo apt更新& sudo apt升级&& sudo apt自动删除-y，然后重新启动笔记本电脑。通过软件和更新安装此驱动程序: NVIDIA驱动程序从nvidia 525重新启动膝上型计算机打开终端，然后运行: sudo apt安装linux 22.04c linux-tools-oem-22.04c -y，重新启动笔记本电脑并再次检查。

这是linux-oem-22.04c和linux-tools-oem-22.04c的最后一次安装，虽然我尝试过nvidia驱动程序，但我以前从未做过。我希望这对其他人有帮助，感谢所有回应的人。
