HATs and other add-ons • After latest updates, HATs report "Humidity Init Failed"

$

On all 5 of my RPIs (3 3B+, a 4 and a 5) Python calls to get_temperature (get_temperature_from_humidity) and get_humidity fail with:

OSError: Humidity Init Failed

This happened after I did my weekly sudo apt update and sudo apt upgrade on all 5.

Searching uncovered years old problems, none of those solutions worked.

Any idea what went amok in the last week?

For a workaround I used get_temperature_from_pressure and faked the humidity with a constant (the value is only reported).
