I am having an issues updating my raspbian operating system. After running sudo apt-get update && sudo apt-get upgrade -y I receive the following error messages:

It seems that python-automationhat does not want to cooperate and either purge from the system or update properly. I've tried this:

sudo dpkg -i --force-overwrite /var/cache/apt/archives/python-automationhat_0.2.0_all.deb

And this:

sudo apt remove python-automationhat

I've also tried installing the missing module with:

python pip install ConfigParser

The dpkg -i --force-overwrite and sudo apt remove both come back with errors about having to reinstall the package before continuing, I've also tried that and it still does not work.

Current Raspbian version:

Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 9.11 (stretch)
Release:        9.11
Codename:       stretch

Python version: Python 3.5.3

Seems you have done things disordered that may have done it worse. Lets try to do it step by step. First don't chain commands if you have trouble so you can see what command gives what messages:

rpi ~$ sudo apt update
rpi ~$ sudo apt full-upgrade   # yes, not only an upgrade

It's likely that you still get the error. Then you should reinitialize the package list. If it doesn't help you should follow the error messages about having to reinstall the package before continuing. You told that you have done it but don't show how. Use this command:

rpi ~$ sudo apt install --reinstall python-automationhat
rpi ~$ sudo apt full-upgrade

By the way, this is for python2. Because you use python3, you do not need it. Then you mentioned python pip install ConfigParser. It is unclear why do you do that. Beside that it is also for python2 and useless for you, you should not use pip3 if possible (never use pip). We have seen many trouble with it because it doesn't fit optimal into Raspbian and mostly you have to adapt it. I only have the buster repository available and there I find

rpi ~$  apt list *configparser
Listing... Done
cl-py-configparser/stable 20170830-1 all
python-configparser/stable 3.5.0b2-1 all

I suppose you will find it also in the stretch repository. You should use this package because it fit best into the Raspbian operating system.

In general you should take more care what python version do you use and install.

I had both Python 2.X and Python 3.X installed on the same RaspberryPi (/usr/bin/python was pointing to Python 3.X) and faced a similar problem during apt-get upgrade.

I was able to solve the problem by

  1. Linking /usr/bin/python to Python 2.x's executable
  2. Executing apt-get upgrade
  3. Linking /usr/bin/python back to Python 3.x's executable

I suggest installing python 2.7 and executing apt-get upgrade again.
