Hi, Key management by apt has evolved, I have not yet updated the installation procedure... here's what to do:

wget -O- http://www.piduino.org/piduino-key.asc | sudo gpg --dearmor --yes --output /usr/share/keyrings/piduino-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/piduino-archive-keyring.gpg] http://apt.piduino.org jammy piduino" | sudo tee /etc/apt/sources.list.d/piduino.list
sudo apt update

Thanks!

I deleted also the file "archive_uri-http_apt_piduino_org-jammy.list" in /etc/apt/sources.list.d.
