Answer 1

The answer here is clear: you are using an unsupported Python (2.7). Newer versions of Python included new syntax, so you will find this kind of messages. There are 2 options to work around this:
Don't use the latest versions of packages and extensions. This is not a great idea, though. Do it if you really need Python 2.
Update your Python version. Consider Python 3.7 or greater.

Answer 2

Remove python2
sudo apt purge -y python2.7-minimal
