Ubuntu 出现apt-get: Package has no installation candidate问题
今天在安装软件的时候出现了Package has no installation candidate的问题，如：
# apt-get install <packagename>
Reading package lists... Done
Building dependency tree... Done
Package aptitude 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 <packagename> has no installation candidate
解决方法如下：
# apt-get update
# apt-get upgrade
之后在安装就可以了
# apt-get install <packagename>
今天在装环境的时候 遇到了这个问题，百度了一下 感谢 原作者 原文链接http://blog.csdn.net/liuyifeng_510/article/details/7081490
