网上查资料说是软件安装源没有这个软件，需要添加软件源。

1.备份源列表

sudo cp  /etc/apt/sources.list  /etc/apt/sources.list.bak

2.添加源列表

在这个网站上选择适合你的版本型号的源列表（一定要选对版本）

http://wiki.ubuntu.org.cn/Qref/Source#Hardy.288.04.29_.E7.89.88.E6.9C.AC。

3.刷新列表

sudo apt-get update

sudo apt-get upgrade

以上是网上搜到的资料，说是很多都那样解决了，

但是尝试了如下一堆的软件源还是没有成功安装memcached的客户端libmemcached。

暂时不使用apt-get方式安装libmemcached，换用编译安装的方式。

1. 下载libmemcached，当前最新版本：libmemcached-1.0.18.tar.gz，官网：https://launchpad.net/libmemcached/

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

2.解压

tar zxvf  libmemcached-1.0..tar.gz

3.进入目录

cd libmemcached-1.0./

4.编译安装

./configure
make
sudo make install
