在使用apt-get install XXX，报E: Unable to locate package XXX

一、在使用apt-get install XXX安装某个软件的时候，经常会出现一个错
例如以mysql为例：

root@iZ2zeht3zvxbq5ycy698pwZ:~# apt-get install mysql-server
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package mysql-server

二、一般这样的问题，多出现于只需要升级一下安装源就好了

root@iZ2zeht3zvxbq5ycy698pwZ:~# apt-get update
Get:1 http://mirrors.cloud.aliyuncs.com/ubuntu xenial InRelease [247 kB]
Get:2 http://mirrors.cloud.aliyuncs.com/ubuntu xenial-updates InRelease [102 kB]
Get:3 http://mirrors.cloud.aliyuncs.com/ubuntu xenial-security InRelease [102 kB]
Get:4 http://mirrors.cloud.aliyuncs.com/ubuntu xenial/main Sources [868 kB]
Get:5 http://mirrors.cloud.aliyuncs.com/ubuntu xenial/universe Sources [7728 kB]
Get:6 http://mirrors.cloud.aliyuncs.com/ubuntu xenial/main amd64 Packages [1201 kB]

三、再安装就好了，不会再报错了

root@iZ2zeht3zvxbq5ycy698pwZ:~# apt-get install mysql-server
Reading package lists... Done
Building dependency tree       
Reading state information... Done
