Thank you "birdmun". As I am a total novice in this Linux world, with maybe a month exposure to it, I am a total ignoramus on the terminology. So what is a PPA?? I would prefer not to have to do a reinstall if I can avoid it. Again excuse my ignorance, but what is an Apppack image?? I have seen the snap install mentioned but did not want to touch any of that stuff as I had no idea what it meant. Is there a site somewhere that I should look at to get an understanding of all this stuff. Being on top of my profession, it is somewhat embarrassing being so ignorant in an all new field. Again my humble apologies for that.
Blessings and kindest regards to you.
