无法在内核为 4.15.0-76-generic 的 Ubuntu 18.04 上使用 r8168 驱动程序连接到 PCI 以太网

我看到我安装的 Ubuntu 18.04 上的默认驱动程序是 r8169。

然后我按照这个指南（https://unixblogger.com/how-to-get-your-realtek-rtl8111rtl8168-working-updated-guide/）建议

sudo apt-get install r8168-dkms

这是成功的，但重新启动后，仍然没有以太网连接。

sara@sara-Aspire-V5-591G:/usr/lib$ dkms status
r8168, 8.045.08, 4.15.0-76-generic, x86_64: installed

sara@sara-Aspire-V5-591G:/usr/lib$ modinfo r8168 | grep -i version
version:        8.045.08-NAPI
srcversion:     45361C7A45067DE67257C08

如果我执行 ifconfig，我会看到
