E: 包 'cassandra' 没有安装候选

Question

我试图在Ubuntu 14.04安装卡桑德拉和我面临的，当我运行这个命令这个问题：sudo apt-get install cassandra。

 Reading package lists... Done
 Building dependency tree 
 Reading state information... Done
 Package cassandra 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 'cassandra' has no installation candidate

请帮我修复它。尝试了一些链接，但没有奏效。我需要在我的机器上安装 cassandra

在 /etc/apt/sources.list 中，找到描述 Debian 源代码存储库的行，并将 contrib non-free 添加到该行的末尾。例如： deb http://some.debian.mirror/debian/ $distro main contrib non-free
