I downloaded the Minecraft.deb file from minecraft.net and tried to install it first with the normal software installer GUI. What would happen is it would go from 0% to 100% really fast and then the install button would reappear as if nothing happened.
Then I tried the
dpkg -i method using
sudo dpkg -i Minecraft.deb but it gave me this error:
dpkg: error: cannot access archive 'Minecraft.deb': No such file or directory.
Then I tried doing it with the path:
sudo dpkg -i /home/Downloads/Minecraft.deb. Still didn't work. I don't understand why.
