I trust them as well. I just have read quite a few of your posts here because of the relevant questions you pose, and the solutions you catalog as they lay the ground work for those coming behind you. I asked more for curiosity because Ubuntu 20.04 LTS is reportedly slightly faster from a boot perspective, and I did not want to make the assumption that I should ignore the offer of the upgrade. With as many features and security fixes as the Openemr developer team tends to roll out, I doubt there is time to document everything so better to ask than miss out.
