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