It looks like the PPA is not working properly. You can add the repository manually though:
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee -a /etc/apt/sources.list.d/mongodb-org-3.0.list
echo "deb http://repo.pritunl.com/stable/apt trusty main" | sudo tee -a /etc/apt/sources.list.d/pritunl.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv 7F0CEB10
apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv CF8E292A
apt-get update
Once you’ve done that, you should be able to install the packages.
