I am new to Ubuntu and have been researching varies methods to accomplish certain tasks that I want done. Some of my research has led me to questions asked in 2012. And I am hesitate in trying the answers/suggestions to those questions. I am working with Ubuntu 18.04.3 LTS (Gnome 3) for now and have installed kubuntu.desktop (Plasma). So, are questions asked 'n' years ago, still relevant to current supported Ubuntu distro's and officially recognized derivatives? If that is the case, are deprecated Q&A removed?
If this is a duplicate then I will remove, but I didn't see any questions concerning this topic.
