Ubuntu jammy is not in beta. It is a full ubuntu release.
It would not be a unreasonable expectation to have the packages be available on the current lts ubuntu release. If urbackup is only going to support 22.04 until when 2.5 is fully released I will need to investigate a new solution as I can not use a software that will cripple itself if you update the underlying operating system to the latest LTS version.
