如何在Ubuntu 16.04中安装python2.7

我正在尝试在 Ubuntu 16.04 上安装 Python 2.7。当我尝试python或python2或 时python2.7，我收到以下消息：

 The program 'python' can be found in the following packages:
 * python-minimal
 * python3
 Try: sudo apt install <selected package>

运行后sudo apt install python2.7，我收到以下消息，但是当我输入时 python 仍然不可用python。

Reading package lists... Done Building dependency tree Reading state
information... Done You might want to run 'apt-get -f install' to
correct these: The following packages have unmet dependencies: 
mongodb-compass : Depends: gvfs-bin
                  Depends: python but it is not going to be installed     
python2.7 : Depends: python2.7-minimal (= 2.7.12-1ubuntu0~16.04.3) but 
it is not going to be installed
            Depends: libpython2.7-stdlib (= 2.7.12-1ubuntu0~16.04.3) but   
it is not going to be installed
E: Unmet dependencies. 
Try 'apt-get -f install' with no packages (or specify a solution).

我也尝试过：

  • sudo apt install python
  • sudo apt install python2.7
  • sudo apt install python2
  • sudo apt-get install python
  • sudo apt-get install python 2.7
  • sudo apt-get install python2

到现在为止什么都没有起作用。

我只需输入 即可访问 Python3.5 python3，但我需要 python2.7。我在尝试安装 python 之前更新了存储库。我做错了什么？

运行python的缓存策略：

python2.7:
