Many thanks for your report.

This is the issue, I'm working on a workaround for tomorrow: #4928

I'll close this in favour if the linked issue.

@MichaIng
but this is a bullseye system

[MichaIng]

Ah whoops, right.

@maury77
Please try:

apt install libblas3
systemctl restart home-assistant

Which additional modules have you installed in Home Assistant? This library seems to be not required on a fresh HA, but probably some extension does.

No it is not generally required on Bullseye, but likely an extension you use pulls a Python modules from piwheels.org which requires it. It is expected that additional packages are required when using HA extension, which is the reason we have these dietpi.txt settings 🙂: https://github.com/MichaIng/DietPi/blob/a4cf2c5/dietpi.txt#L261-L266
