Python 在Ubuntu 16.04 lts中安装mysql工作台时出错

我在UBUNTU 16.04 lts上安装mysql workbench时遇到问题，当尝试安装时，它返回错误，说我对python没有任何依赖关系，但我也无法安装依赖关系

sudo apt-get install mysql-workbench

                   Depends: python-mysql.connector but it is not going to be installed

                   Depends: python-pexpect but it is not going to be installed

请注意，它要求python>=2.6.6，我的python版本为2.7.12

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pythonpip，得到了以下错误

sudo apt-get install python-pip

有人有过这个问题吗

注意：无论是我可以安装的终止符，在python的依赖关系方面都会出现同样的问题

不起作用。指责同样的错误。在几次失败的尝试后，解决方案是格式化PCP，但都没有成功。指责同样的错误。在几次失败的尝试后，解决方案是格式化电脑
