Using Python-TUF, but it's purpose is not to package app, check new version and apply updates and patches, so a non negligible layer of development is needed to achieve the same work as the first choices.

Confusingly named, it’s not a framework, but a specification that developers can follow when implementing their update systems to help users know they can trust the updates they receive. There’s also a Python reference implementation.

Hello world! I want to recommend a wonderful open-source package called Tufup. It's a simple software updater for stand-alone Python applications. This package was created as a replacement for PyUpdater, given the fact that PyUpdater has been archived and is no longer maintained. However, whereas PyUpdater implements a custom security mechanism to ensure authenticity (and integrity) of downloaded update files, Tufup is built on top of the security mechanisms implemented in the python-tuf package, a.k.a. TUF (The Update Framework). By entrusting the design of security measures to security professionals, Tufup can focus on high-level tools.
