I just wanted to install decent on my brand new mini PC with ubuntu 22.04. After adding the repository and doing apt update, there is the error message:
“The repository ‘http://phoscon.de/apt/deconz jammy Release’ does not have a Release file.”
However if I change /etc/apt/sources.list.d/deconz.list from jammy to focal (20.04), I can install deCONZ and everything is working fine.
So could you please add the release also for jammy?
