当在Ubuntu系统中遇到`E: Unable to locate package`或软件中心无法找到软件资源的问题，通常是由于安装源未正确配置。解决方法包括编辑位于`/etc/opt/sources.list`的安装源文件，替换为国内镜像地址，如将`trusty`替换为对应Ubuntu版本名，然后用`sudo cp sources.list /etc/opt/sources.list`命令更新。确保拥有root权限执行此操作。

【解决场景】：

1.无法找到软件包

apt-get install : E: Unable to locate package xxx

软件中心安装时显示：There isn't a software package called "Smile" in your current software resources

2.可以找到软件包，但无法自动安装依赖

The following packages have unmet dependencies:
 package1 : Depends: package2 (>= 1.8) but 1.7.5-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

【解决方案】

以上问题都由源没有添加安装源导致的。

源所在位置：/etc/opt/sources.list

安装源模板：
