I am trying install Kurento Media Server. From installation guide in it's official website, I follow:
sudo add-apt-repository ppa:kurento/kurento
sudo apt-get update
sudo apt-get install kurento-media-server
Actually, the executing of last command line prompts up a message as below:
root@ubuntu:~/build# sudo apt-get install kurento-media-server
Reading package lists... Done

Reading state information... Done
Package kurento-media-server is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'kurento-media-server' has no installation candidate
root@ubuntu:~/build#
I am using Ubuntu 14.10 (latest stable version).
Launchpad only has the deb package for Trusty. If you want to install kurento-media-server in Utopic, you'll have to add Kurento's own repository
sudo apt-add-repository http://ubuntu.kurento.org
wget -O - http://ubuntu.kurento.org/kurento.gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install kurento-media-server
