I upgraded to bookworm today and so far all works fine. However, when I carry out
sudo apt update && sudo apt full-upgrade
I get the following warning:
W: http://phoscon.de/apt/deconz/dists/bookworm/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
The warning is shown since Debian APT repositories have change how GPG keys are stored.
Note this is only informative not a problem for actual functionality.
The deCONZ APT repository currently still uses the old way since we support multiple Debian/Ubuntu versions. However I think we can move on since all supported versions should be recent enough to support the new key handling, we’ll have a look how to make this.
