Ubuntu 16.04（AWS EC2）上的python依赖关系被破坏

我试图删除Ubuntu 16.04上安装的所有python。现在，我明白我不应该这么做。然而，仅仅尝试重新安装python是行不通的

当我尝试

$ sudo apt install -f --reinstall python3

我尝试过不同的事情，但在这一点上，我不知道如何解决这个问题

$ sudo apt-get -f install dh-python

dh-python is already the newest version (2.20151103ubuntu1.1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 dh-python : Depends: python3:any (>= 3.3.2-2~)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

也许从带有

sudodpkg-i

的deb包安装python是一个更好的主意？您可以下载它，例如

您应该尝试：

sudo-apt-get-update

然后尝试使用下面的命令卸载python

sudo apt purge python3.x-minimal

如果卸载成功，则

在ubuntu从16升级到18之后，我遇到了类似的python3问题。但是你可以试着用我16号的解题法。只需针对

apt

注意：我需要在我的系统中安装python2.7

我遵循这些步骤：

卸载所有python3软件包：

sudo-apt-remove-python3&&sudo-apt-autoremove

但这对我没有帮助。因此，将尝试定义系统中仍存在哪些包：

apt列表--已安装| grep python*

正如我们所看到的，一些python3包在系统中。将删除它们

sudo apt删除libpython3 stdlib libpython3.5 libpython3.5-minimal libpython3.5-stdlib libpython3.6 libpython3.6-minimal libpython3.6-stdlib

现在，尝试安装python3

sudo apt安装python3

一切都会好起来的
