I'm trying to install blockstream satellite on a Debian GNU/Linux 12 (bookworm) using the following commands, according to your instructions:
sudo add-apt-repository https://aptly.blockstream.com/satellite/debian/
sudo apt-key adv --keyserver keyserver.ubuntu.com
--recv-keys 87D07253F69E4CD8629B0A21A94A007EC9D4458C
sudo apt-get update
sudo apt-get install blockstream-satellite
After the last command, I get the response that blockstream-satellite is not found.
