With the upcoming releases Ubuntu 22.04 (due April 2022) and Debian bookworm (estimated release date March 2023) OPM will officially become part those Linux distributions. During the past year we worked hard to align the package building process with those Linux distributions.
We are grateful for the help that was provided by the Debian Developers during that work. Special thanks go to the Developers Anton Gladky and Nilesh Patras for sponsoring the upload of the prepared packages and Graham Inggs for helping with the transition to Ubuntu. Of course the great packaging effort done by Arne Morten before that for the Ubuntu PPA made our life a lot easier.
