Kurento服务器安装

Kurento服务器安装

Kurento媒体服务器（Kurento Media Server ,KMS）必须安装在Ubuntu 14.04 LTS (64 bits)系统上。安装过程中如果遇到一些意料之外的问题，通常重启可以有效解决。
在终端中键入下列命令：

echo "deb http://ubuntu.kurento.org trusty kms6" | sudo tee /etc/apt/sources.list.d/kurento.listwget -O - http://ubuntu.kurento.org/kurento.gpg.key | sudo apt-key add -sudo apt-get updatesudo apt-get install kurento-media-server-6.0

现在Kurento媒体服务器已经安装好了，键入下列命令来启动和停止Kurento媒体服务器：

sudo service kurento-media-server-6.0 startsudo service kurento-media-server-6.0 stop

以上是Kurento官方网站中的文档里关于Kurento媒体服务器安装中的第一段的中文翻译。但其中的部分描写与我实际安装过程有些区别。例如，现在的Kurento服务器并不需要必须安装在Ubuntu 14.04 LTS (64 bits)，我安装的系统为Ubuntu 16.04 LTS (64 bits)。
以及在进行键入上面的安装命令过程中，在进行到sudo apt-get install kurento-media-server-6.0时，报出了下述错误提示：

通过搜索查询，获取到以下信息：

Your are probably using trusty repositories, because there are the ones indicated by the documentation.

If you are using xenial, you should change your configuration file /etc/apt/sources.list.d/kurento.list

deb http://ubuntu.kurento.org xenial kms6

Then try sudo apt-get update && sudo apt-get install kurento-media-server-6.0 again.

By the way, take into account that kurento officially supports only trusty (14.04). xenial works, but documentation is done for trusty only.

在按照回答中修改了/etc/apt/sources.list.d/kurento.list文件后，再次尝试安装时就安装成功了。
