I am trying to install and setup Ubuntu 18.04 or Ubuntu 20.04.1 on my PC with: motherboard: Asus TUF B550m-Plus Processor: Ryzen 5 3600 Kernel: 5.4.0-42-generic
The problem is that I do not get my network card (RTL8125) recognized therefore I cannot install any drivers using apt-get. To make problem worse build-essentials were not installed during the ubuntu installation therefore I cannot use MAKE to install RTL8125 driver. I also tried to install new kernels (5.7,5.8 and 5.9) by downloading 4 .deb files representing headers,image and modules but it fails after unpacking linux-modules with error "unexpected end of file" (I tried downloading it again and the same happened).
I am stuck in vicious circle where I am always missing something to make this work. Can someone please help me and suggest what Ubuntu version should I install?
