sudo apt-get update
sudo apt-get upgrade -y

It will fail when upgrading. Because this command is updating sources.list again. Because of this, it shows this error. You can run sudo apt-get update && sudo apt-get upgrade -y again. It's ok.

It seems like you don't have the host properly set on the /etc/hosts file. In order to fix it, you should add raspberry to this same file. You can do so by making sudo nano /etc/hosts and adding this username next to the one you already have after the 127.0.1.1 address. Not after the word localhost (most surely you will have to edit the second line).
