Thanks for the respond.
(1) The applications requires password, so I always give user password and it was accepted normally. I had problem the settings. When I had booted as root, the applications did not accept any image and/or avatar from the user's library only when I had copied them from the user's library to the library of root, and then works.
Usually to boot as root was never necessary for this settings, the applications works properly by user's itself.
(2) When I am forced to make an re-install, it does mean a clean install - at least for me.
No Covid for all Sparkers.
