I just had to reinstall my pi cause my sd card was damaged.
During the installation of my RaspBeeII I got again the warning about apt-key.
Now I tried to use keyrings instead but its not working maybe someone can tell me what I´m doing wrong.
curl -fsSL “http://phoscon.de/apt/deconz.pub.key” | gpg --dearmor > deconz.gpg
sudo mv deconz.gpg /usr/share/keyrings
sudo chmod u=rw,g=r,o=r /usr/share/keyrings/deconz.gpg
echo ‘deb [signed-by=/usr/share/keyrings/deconz.gpg] http://phoscon.de/apt/deconz $(lsb_release -cs) main’| sudo tee /etc/apt/sources.list.d/deconz.list
If I now try to install I got the message that the package deconz cannot be found.
Hope someone can help me
