我想在我的linux机器Ubunto 14.04中安装Kurento（http://www.kurento.org/documentation）。
我按照以下安装说明进行操作：
echo "deb http://ubuntu.kurento.org trusty kms6" | sudo tee /etc/apt/sources.list.d/kurento.list
输出结果为：
deb http://ubuntu.kurento.org trusty kms6
然后：
wget -O - http://ubuntu.kurento.org/kurento.gpg.key | sudo apt-key add -
输出结果为：

然后：
sudo apt-get update
