On Raspberry Pi OS Bookworm, when running the RB24 installation script, sometimes one gets following error, and rbfeeder fails to install
Get:6 https://apt.rb24.com bookworm InRelease [2,431 B]
Err:6 https://apt.rb24.com bookworm InRelease
Sub-process /usr/bin/sqv returned an error code (1), error message is: Missing key 307E0F48FB61F7C75BE98B79F2A8428D3C354953, which is needed to verify signature.
Error: The repository 'https://apt.rb24.com bookworm InRelease' is not signed.
Notice: Updating from such a repository can't be done securely, and is therefore disabled by default.
Following is the workaround:
First fix the keyt error by following commands:
NOTE: Some commands, particularly the last one below are very long, and may not be fully visible. Scroll right to see and copy these in full.
sudo apt install dirmngr
sudo apt install gnupg
gpg --keyserver keyserver.ubuntu.com --recv-keys F2A8428D3C354953
gpg --export --armor F2A8428D3C354953 | sudo gpg --dearmor -o /etc/apt/keyrings/rb24.gpg
echo "deb [signed-by=/etc/apt/keyrings/rb24.gpg] https://apt.rb24.com/ bookworm main" | sudo tee /etc/apt/sources.list.d/rb24.list
After fixing rb24 key as above, run following commands to install rbfeeder:
sudo apt update
sudo apt install rbfeeder
After installation is completed, signup as follows:
sudo systemctl restart rbfeeder
After a few seconds, RBFeeder will connect to the AirNav servers and you can view your sharing-key with this command:
sudo rbfeeder --showkey
If you already have a sharing-key from a previous installation, you can set the same key using this command:
sudo rbfeeder --setkey ‹your sharing key›
And that is all. The rbfeeder installation is completed.
Che ck status by following command
sudo systemctl status rbfeeder
TRIXIE
Currently (12th July 2025), the RaspberryPi OS Trixie & Debian 13 Trixie are in testing stage. The "Debian Trixie Stable" is expected to be released shortly, most likely in a month or two. Release of the Raspberry Pi OS Trixie will take another couple of months after Debian Trixie (Stable) is released. RB24 feeder for RPi Trixie will be available couple of months after release of RaspiOS Trixie.
