The tab autocompletion is not working anymore. Instead I get the following message:

┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 9.0, Release Date: 2020-01-01                     │

/usr/lib/python3.8/site-packages/jedi/cache.py:111: DeprecationWarning: Deprecated since version 0.16.0. Use get_signatures()[...].params
  result = method(self, *args, **kwargs)

What can I do to solve the problem?

Please provide more information. For example, how did you obtain Sage? What is your OS?

Python 3.8.2 is not yet offically supported

My OS is Manjaro 19.0.2 and I obtained Sage via pacman (the Arch repositories).

I confirm the behavior on up to date archlinux. This is annoying.

With the same python 3.8.2 ?

This is an incompatibility between jedi 0.16 and ipython, nothing to do with sage itself. The reason why it's only an issue on sage is because ipython hides all warnings by default and sage doesn't. I've pushed sagemath-9.0-12 with a workaround until this is fixed in ipython
