在用software center装IDLE时 出错

details 说python2.7-tk是虚拟的包什么的  不懂..

于是用 sudo app-get install python2.7-tk

发现   几个 depended on xx

少什么就安装什么

sudo app-get install xx

于是发现问题

Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

sudo apt-get upda了两次都是同样的问题

想想应该是源的问题  最近好像改过

于是

sudo gedit /etc/apt/sources.list

发现我的版本是trusty  结果用的  raring

果断ctrl+H  replace之

哦了..

对了一般都会备份..  sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

之后别忘了 sudo apt-get update

附上源地址(直接拷贝进sources.list即可)
