Hi George, thank you for answering me.. Yes I have two user name how you said what you say is right: <"You should not need to be in the wheel group if your username is in "/etc/sudoers"">.
My name was not , at the moment that I had the problem, in the sudoers file . Later I added it , and this wast enough to gain again the sudo privileges.. Probably the cancellation was caused by the command <sudo usernod -G audio <my_name> Now the problem is solved, as well it seems me strange that adding a new group to a user should delete it from the list of sudoers Again thank you to all that tried to help me Angelo On Sun, Dec 27, 2020 at 5:10 PM Qiyu Yan <yanq...@fedoraproject.org> wrote: > George N.
