I've been trying to run Minecraft on Ubuntu 15.04 for a while. Whenever I try running, it won't download the launcher pack and it gives me this message:

I've downloaded the launcher.pack manually, so it goes into the launcher and shows me the login screen, but then it says it can't access Mojang servers, and I can't get past that. I found someone else with the same problem, and s/he said that his/her problem was solved when s/he switched from OpenJDK (I was using OpenJDK) to Oracle Java (Or at least I tried.) I did that, but nothing changed. This is what happens when I use java -version
