我有一台带有板载网卡但没有 wifi 的台式电脑。使用另一台 ubuntu PC 测试了电缆 + 连接，以确认其可以正常工作。
将 ubuntu 20.04 升级到 22.04 后，我没有网络。
我升级了 NetworkManager 和 netplan，并按照以下步骤操作Ubuntu 以太网在更新后变得不受管理。Nmcli 显示我的以太网设备是非托管的。
但是 nmcli 不仅显示我的设备未被管理，而且 lshw 还显示我的设备未被认领，表明没有驱动程序。
我的电脑缺少我的卡的 alx 驱动程序，但由于没有网络，我无法获取它。所以我尝试从 Ubuntu live disk 22.04 下载它，但由于内核不同，它不起作用。我还尝试下载包含 alx.ko 的这个包；
https://www.ubuntuupdates.org/package/core/lunar/main/security/linux-modules-extra-6.2.0-32-generic因为我的内核是 6.2.0-36-generic，但我在 dmesg 中收到未知符号错误，表明它是为另一个版本编译的。
我该如何让网络正常工作？我试过了所有方法！甚至我的两个 USB wifi 适配器也试过了，但它们都有同样的问题。

答案1
我发现问题了，我下载了错误的内核版本 -32 而不是 -36
以下命令提供了在外部计算机上下载包的正确命令和哈希值：
sudo apt-get download --print-uris linux-modules-extra-$(uname -r)
然后在可以上网的计算机上下载后，返回到原来的机器并执行以下操作：
dpkg -i linux-modules-extra-6.2.0-36-generic_6.2.0-36.37~22.04.1_amd64.deb
