  • Your post shows you are attempting to install python3-distutils_3.6.9-1~18.04_all.deb but it seems to be conflicting with the installed python3.8-distutils 3.8.0-1+bionic2. Is your Python 3.8 install from an unofficial repository? Did you happen to use the Deadsnakes PPA which has a change from last week that addresses this very problem? If not, please tell us where your Python 3.8 came from and if the official Ubuntu Python 3.8 works any better. – GracefulRestart Nov 20 '19 at 18:39
  • After installing ubuntu i was installing python 3.8 following unofficial repository you are guessing following this link https://vsupalov.com/developing-with-python3-8-on-ubuntu-18-04/ – Ciasto piekarz Nov 20 '19 at 21:23

According to this change log notice for the latest revision of their Python 3.8 release, the maintainers of the Deadsnakes PPA acknowledged that their release conflicts with upstream Ubuntu.

First update python3.8 to the newest release or remove it entirely. You want to ensure the removal of the python3.8-distutils, python3.8-tk, python3.8-gdbm, python3.8-lib2to3 packages, after which you should no longer be conflicting with Ubuntu packages.

You should then be able to install python3-distutils from the official Ubuntu repositories, which should fix the virtualenv issue you are experiencing.
