As you might know, starting from Ubuntu 20.04 LTS, Python 2 is no longer a dependency and not installed by default anymore. However, there are still some caveats:
- When installing Python using
apt install pythonit will still install Python 2 - When upgrading from an older Ubuntu version,
pythonwill still point to Python 2
The fix is simple: install the python-is-python3 package:
sudo apt install python-is-python3
After installing this package, running apt install python will give you Python 3 and if you had already installed Python, python will now actually point to Python 3.
Finally, no more Python 2!
