I tried to install TeamViewer and have gotten this far (below) so I would like to delete it all and update my OS from 19.04 to 20.04 before proceeding with TeamViewer.
My second question; if allowed, is how did they all get there? I think because perhaps I tried to install 2 different versions...
I am still very new at this and am struggling through learning as I go. Thank you.
