省流版

今天装python，版本装错了。

然后删又删不掉，装pip又装不上，报错是这样的：

想装的时候：

7f2a0f717aa3:~/$ sudo apt-get install python3-pip python3-setuptools
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
python3-setuptools is already the newest version (45.2.0-1ubuntu0.1).
python3-setuptools set to manually installed.
python3-pip is already the newest version (20.0.2-5ubuntu1.7).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python3-pip : Depends: python3-distutils but it is not going to be installed
               Recommends: build-essential but it is not going to be installed
               Recommends: python3-dev (>= 3.2) but it is not going to be installed
 python3-setuptools : Depends: python3-distutils but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

想删掉的时候：

7f2a0f717aa3:~/$ sudo apt-get autoremove
Reading package lists... Done

想按照提示apt --fix-broken install的时候，一直这样：

7f2a0f717aa3:~/$ sudo apt-get install -f

The following additional packages will be installed:

The following NEW packages will be installed:
  python3-distutils python3-lib2to3

Abort.

New Bing告诉我可以这样解决，如下：

有一些可能的解决方案是：

1. 运行apt --fix-broken install命令来修复损坏的依赖关系。
2. 运行apt-get update和apt-get upgrade命令来更新软件包列表和安装最新版本的软件包。
3. 运行apt-get install -f命令来尝试自动修复依赖关系问题。
4. 运行dpkg --configure -a命令来配置所有未配置的软件包。

前面三种对我没用，我试过很多次了还是一直报错，导致其他包也装不上。于是用了第四种，然后继续报错：

7f2a0f717aa3:~/$ sudo dpkg --configure -a 
dpkg: error: requested operation requires superuser privilege
shandian@7f2a0f717aa3:~/fuzzware$ sudo dpkg --configure -a

NewBing说：

根据网上的信息，您可能遇到了dpkg处理python3-pip软件包时的错误。
有一些可能的解决方案是：

1. 运行sudo dpkg --remove --force-remove-reinstreq python3-pip python3-setuptools python3-wheel命令来强制删除有问题的软件包。
2. 运行sudo apt-get install python3-pip python3-setuptools python3-wheel命令来重新安装这些软件包。
3. 运行sudo apt-get -f install命令来尝试自动修复依赖关系问题。

第一种方式work for me。

7f2a0f717aa3:~/$ sudo dpkg --remove --force-remove-reinstreq python3-pip python3-setuptools python3-wheel

感谢NewBing。
