Hi,
basically you would have 2 options.
-
download a new fresh Buster image and start a clean install from scratch https://dietpi.com/downloads/images/DietPi_PINEA64-ARMv8-Buster.7z
-
perform an in-place upgrade following this guide https://dietpi.com/forum/t/qbittorrent-version-shipping-with-dietpi/2326/9
originally the guide was intended for Raspberry Pi devices but with smaller adjustments on the apt source list’S, it should work on a Pine A64 as well. If all is working fine, Python should be updated to version 3.7 and I would recommend to reinstall Docker Compose after your system has been reboot.

Disclaimer: Whatever you do, you will do it on your own risk. It’s highly recommended to do a full backup of your SD card before. Best would be to clone it, because the upgrade will touch nearly every installed packaged.
