Hello!, This is the first time for me consuming Ubuntu repositories from OBS. I've rebuilt a Ubuntu 23.04 package for Ubuntu 22.04, added the repository according OBS indications but I'm struggling with GPG signature validation. Client setup: --- sudo sh -c 'echo "deb http://download.opensuse.org/repositories/home:/ciriarte:/apstra-4.2.0-fix/x... /" | sudo tee /etc/apt/sources.list.d/home:ciriarte:apstra-4.2.0-fix.list' sudo sh -c 'curl -fsSL https://download.opensuse.org/repositories/home:ciriarte:apstra-4.2.0-fix/xU... | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_ciriarte_apstra-4.2.0-fix.gpg > /dev/null' sudo chmod a+r /etc/apt/trusted.gpg.d/home_ciriarte_apstra-4.2.0-fix.gpg sudo chmod a+r /etc/apt/sources.list.d/home:ciriarte:apstra-4.2.0-fix.list sudo apt update --- Error I'm getting: --- Err:5 http://download.opensuse.org/repositories/home:/ciriarte:/apstra-4.2.0-fix/x...
