I guess you did way more than this. Because you have a failed HA install / re-install process. This has nothing to do with dietpi-update, apt-get update or apt-get upgrade 
The issue is with piwheels.org as we use pre-compiled wheels. Actually, builds for cryptography failded due to Rust dependency. We tried to assist piwheels.org guys but no luck so far.
