I've just installed RHEL 7.6. I've installed Base environment: Server with GUI with all addons for selectred environment
During Installation I created Root Password & created user from User Creation with, Make this user administrator option
Now, post install & after successful login to RHEL environment, I'm unable to install any software or access KUser to edit user permission or change user group
While installing anything it gives error something went wrong, Error msg when trying to use KUser , Error opening /etc/shadow for reading
How to give root permissions to user created during Installation?
