You should always start by updating your apt packages list and upgrading the currently installed packages in your Ubuntu machine. Once that is done, check if this process has installed the correct version of Python on your Ubuntu machine, which is highly likely.

Otherwise, you must add a custom repository containing the desired python3 version to the apt package list. Then, you can install it without errors using the apt package manager.
