[SOLVED] Trying install python-psycopg2 breaks Ubuntu 16.04 apt

Issue

After trying to install python-psycopg2 with

sudo apt install python-psycopg2

apt breaks and I cannot even purge that package.

I've got an error when I try to purge with

sudo apt purge python-psycopg2

Error:

Traceback (most recent call last):

    from debpython.version import SUPPORTED, debsorted, vrepr, \
  File "/usr/share/python/debpython/version.py", line 24, in <module>

I already try

sudo apt clean
sudo apt autoclean
sudo apt autoremove
sudo apt install -f

without success.

I'm using python 3.5. Is it possible that the broken issue caused by trying to install python-psycopg2 instead python3-psycopg2?

I'm halted here. Any help would be great!

Solution

Yes, you should install the right version of the library for your Python version. If a python3-psycopg2 package exists you should install that; however note that it is not generally recommended to use your distribution's packages to install Python libraries, since they are usually out of date. Instead you should use pip (or pip3) to install libraries directly from the Python packaging index.
