I have experienced the same issue on Ubuntu 18.04 during the installation of the OpenSTLinux Yocto layer with the following command:
repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-20-11-12
Returns:

This issue goes away with using Python3 instead of Python (2.7). You can do this:
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python3 /usr/bin/python
