OctoPrint tells me my Python environment is outdated and will soon no longer be supported, how do I upgrade?

There was something more than the plugin problem.

The authentication error would render me unable to install any plugin onward.

I even tried to update the user password thinking it could be some data migration problem, but it also failed (the dialog never saved, it also showed no error message at all)

Maybe something to do with the Argon2 alerts on the logs.

I don't see why you shouldn't be able to upgrade Python and then upgrade the virtual environment created by octoprint_deploy, without any need to go through a full removal and restore. What am I missing?
