[Julian Andres Klode (juliank)]

The dump function is part of the standard library json module, did you perhaps have a json.py in the current working directory overriding this or ended up overriding it some other way? Have a look at pydoc json to see where the json module is coming from.

[[e-mail] (iolalla)]

Agree on the analysis, I've discovered that the installation of packages done by Intellij did the wreck. It's a catch cause breaks apt, pip and any tools that uses python and json.

Just in case someone has something similar, I downloaded Ubuntu and reinstalled without formatting to solve the issue.
