Thanks to a tip from Burusutazu, I ran Anywhere from the terminal and saw what the program was missing, that prohibited the program from starting when I clicked its icon.
I just reinstalled Anywhere, since it previously seemed useless to keep it installed. I ran it from terminal and got this response:
republicanywhere: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory.
I checked Synaptic for libgconf-2.so.4: and it found nothing. So it seems that 1) I don’t have it, and 2) Synaptic doesn’t have it either, or at least under that name.
I did an online search for libgconf-2.so.4 and, after another search, found that it needed gconf2. So I had Synaptic install that and then ran republicanywhere from the terminal. republicanywhere popped up just like it knew what it was doing! I logged in and it worked!
So I logged out and then logged back in using the icon to start the program. That worked too. So Thank you for your response. That led me to the answer I needed to have it working now.
So, if you’re finding that clicking the Anywhere icon doesn’t start the program for your Linux install, try this as a possible solution.
Thanks again for your reply, Burusutazu. I’m a happy camper now that I can use Anywhere in Linux Mint 20 Cinnamon.
