This dockerfile works when line 4 (case 1) is uncommented, but fails when line 5 (case 2) is uncommented. I have very puzzled by this. The error (if I understand it) should happen in both cases. See the error trace below.

I haven't solver this. But I made it go away by removing the lines totally and adding these instead (which I got from another Dockerfile):
I believe the public keys for the mentioned repository changed recently, or something like that. Quick fix:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -Then try again.
