Default version of Python in UB 20.04?

Ubuntu has 3.8 as the default Python version, but after the upgrade to UB 20.04, Python2.7 is still the default. Is this just alias/naming or does UB still need 2.7 as default?

No. The default from a clean install in python3.

Since you upgraded, the default python version is kept the same … I am guessing you have python 2 based apps that will break if python3 is the default
