如上，update命令一直无法执行，似乎是重复配置，试过了google第一页的方法，但都不行qwq，于是进行下一步安装继续出错

途中还报错，说没装oracle-java6-installer
sudo apt-get install oracle-java7-installer

请问各位大佬，怎样才能让sudo apt-get update变正常啊？？
还有pycharm安装不成功是什么问题？？

1. 把下面指令 複製 貼進終端機 執行
sudo ls -al /etc/apt/sources.list.d | grep mystic
把指令及回應結果直接 選取/複製/貼上來

2. 建議
等 update 正常了 再進行 安裝/更新

执行：sudo ls -al /etc/apt/sources.list.d | grep mystic
结果是：
-rw-r--r-- 1 root root 218 8月 2 14:31 mystic-mirage-ubuntu-pycharm-xenial.list
-rw-r--r-- 1 root root 218 8月 2 14:31 mystic-mirage-ubuntu-pycharm-xenial.list.save
sudo apt-get update无法执行的问题怎么解决呢？因为这个原因，一直无法安装pycharm

结果是：
-rw-r--r-- 1 root root 218 8月 2 14:31 mystic-mirage-ubuntu-pycharm-xenial.list

把下面指令 複製 貼進終端機 執行

代码： 全选

sudo cat /etc/apt/sources.list.d/mystic-mirage-ubuntu-pycharm-xenial.list

把結果直接 選取/複製 貼上來
