However when I try to access the program manager I get:

Error downloading https://downloads.arduino.cc/libraries/library_index.json

Any ideas, please?

Problem was, I had to LOG OUT (user) then log in again. THEN it worked.

Thanks very much !!

Adding group ‘dialout‘ does not work – ‘usermod‘ command just returns (as root); then users ‘groups’ are still not changed. So cannot use arduino apparently.
