on 32bit we use pre-compiled wheels provided by [piwheels.org](http://piwheels.org). Unfortunately, latest build has been failed there. [piwheels - cryptography](https://www.piwheels.org/project/cryptography/)

Therefore you have issues to set it up.

Bad thing, `cryptography==38.0.3` is explicitly require by Sabnzbd

As a workaround you could try to install Rust + other dependency (required by cryptography) by your own. But it is quite a large build

```auto
curl -sSfL 'https://sh.rustup.rs' -o rustup-init.sh
chmod +x rustup-init.sh
./rustup-init.sh -y --profile minimal
rm rustup-init.sh
source "$HOME/.cargo/env"
dietpi-software install 16 130
apt install libffi-dev libssl-dev
pip3 install cryptography
dietpi-software install 139

```
