我在尝试安装时在UBUNTU 16.04 lts上安装mysql workbench时遇到问题，它返回错误，说我对python没有任何依赖，但我也无法安装依赖项。
sudo apt-get install mysql-workbench

看到它要求python＆gt; = 2.6.6，我在2.7.12版中有python
python --version
Python 2.7.12
我注意到一些python依赖项也丢失了，我尝试安装python PIP并且出现以下错误。
sudo apt-get install python-pip

请注意，它再次抱怨python版本，但我匹配所需的版本，因为它要求＆lt; 2.8和＆gt; = 2.7.5
我认为它可能会让已经安装在ubuntu上的Python 3，其他应用程序使用它，但我不相信。以下是一些已安装的python识别命令。

有没有人遇到过这个问题？
注意：我没有安装的终结器，给出了与python的依赖关系相同的问题。
