After that error if I try sudo apt-get autoremove I get the following error:

Thank you very much for your help!

Hi,

I changed python alternatives from 3.5 to 2.7 and then to 3. Doing so I could remove all above errors. It seems that some dependencies are not dissolved automatically.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi Thomas,

It sounds like you changed /usr/bin/python, and it is no longer a symlink to /usr/bin/python2.7. Is that the case?

ConfigParser is part of the Python 2.7 stdlib. In Python 3 it was
renamed to configparser, so the debpython module won't work with Python
3.

I'm going to mark this bug as Invalid. If this is not the case then please set back to new.

Thanks,
Corey
