At the beginning I would like to emphasize that I've been struggling with this problem for a long time now and all the solutions that I've found so far have failed. I followed this answer, and then I downloaded the drivers from the D-Link website (I will put it in the comment since I cannot post more than two links) and after that I ran those commands (in the folder with the files)
chmod +x install.sh
sudo ./install.sh
which were followed by the long list of errors

After that, I have found another way to approach the problem, using files from this site and following this guide. After running make I received the following list of errors

As you can see, they look pretty similar. To be honest, I have no idea how should I proceed now... I tried looking up the errors, but didn't succeed. To complete the question I'm adding two results about the adapter

I don't know if that's relevant, but when I click on the internet connection icon in the Ubuntu upper-right toolbar, there is RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller option visible (displayed in grey, without way to "interact" with it), followed by disconnected.
As you can see I am totally Ubuntu-noob and would really appreciate your help. Let me know if you need any additional information.
