#### Steps to reproduce

1. Ran Debian 13 Trixie upgrade script several times with the same result, stopping with the same error messages each time.  
Trixie upgrade appears successful, but I receive the same error message regarding “pip3 install -U flask requests” when updating DietPi Software elements.
2. …

#### Expected behaviour

- …

#### Actual behaviour

- Error messages during DietPi Software updates following a Debian Trixie upgrade from Bookworm. Fails at: pip3 install -U flasks requests

```auto
  "Installing collected packages: requests, markupsafe, itsdangerous, click, blinker, werkzeug, jinja2, flask

  │ Attempting uninstall: requests

  │ Found existing installation: requests 2.32.3

  │ error: uninstall-no-record-file

  │

  │ × Cannot uninstall requests 2.32.3

  │ ╰─> The package's contents are unknown: no RECORD file was found for requests.

  │

  │ hint: The package was installed by debian. You should check if it can uninstall the package.”

```

#### Extra details

This RPi 4 Model B is used solely as an ADSB feeder using the ADSB.im Docker package installed via DietPi-Software. The feeder appears to still work after the upgrade to Trixie, but I can no longer access any ADSB.im configuration pages.

I had ensured the previous Bookworm installation was up to date, to include the ADSB.im pacakges.

Trying the upgrade script again and taking a fresh look at the console error messages, it appears the upgrade stops when trying to delete an old version of Python requests (v 2.32.3).

So, I manually deleted the requests folder in /usr/lib/python3/dist-packages. I then re-ran the Trixie upgrade script and all DietPi updates were installed successfully with no error messages.

System appears to function normally after reboot and I can now access the config page for the adsb.im feeder.

Yes starting Debian Trixie, there is a conflict between pure python packages and python apt packages. Because of this, we might move to individual pyenv per application to avoid this conflict in future
