Description

I want to read data from DHT11 sensor. (https://pimylifeup.com/raspberry-pi-dht11-sensor/)

I've installed everything on the right way, nevertheless I cannot read any data.

I cannot do any operation on GPIO. Neither sensors nor relays.

Hi, the code in this area has changed slightly. does upgrading Blinka help? When you upgrade, you may still be prompted to install libgpiod python bindings; clicking that link will take you to the Installer Script library to install and the specific script you will need to use. The library README in the repository has general installation and usage instructions.
