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.
