I installed it using the PPA as described on ... some website? Probably ItsFOSS.com. I should try the appimage.But now that I have Remarkable, I may not need to fix it...although I can't figure out how to UNinstall it. For as long as I've been using Linux, you'd think I'd know more about how to use it.
Every time I hear the word "Progress" my fur bristles!
