[Tails-dev] Tails Vagrant VM: repositories in /etc/apt/sourc…

Thanks for the suggestion to use "vagrant ssh". I am now having a close
look at the VM from inside.

I noticed that all the repositories configured in
/etc/apt/sources.list
use http instead of https.

I suggest to change that to reduce the threat of MITM attacks. To do that
apt-get install apt-transport-https
is required.

I am experimenting with these and other changes.

Cheers,
Andreas
