Hi, I'm looking to install Python 3.8 on an older Ubuntu and I've noticed that a lot of guides are recommending the use of the deadsnakes PPA to do so on Ubuntu. Yours does, on line 23, here: https://github.com/realpython/python-guide/blob/master/docs/starting/install3/linux.rst#L23

This feels...unsafe? Maybe I'm paranoid, but the PPA seems to be maintained by three individuals, and in the PPA's description, it says:

there's no guarantee of timely updates in case of security problems or other issues. If you want to use them in a security-or-otherwise-critical environment (say, on a production server), you do so at your own risk.

Seems like there should be a warning in the guide, at the minimum, or that the guide should recommend installation from source (though it comes with its own problem: timely updates).
