Linux OS Mint 19 Cinnamon. When installing some of the software, cursing access rights. I read Google and did such a thing:

sudo chown -R root.root /usr

After this command sudo . I restored it, but an echo remains from my swing. If through the GUI I want to see users or install or delete something, a password entry window appeared before, nothing at all. The same song, if I want to open the folder with root rights, I click the right Open as root and the window does not appear. Maybe this is somehow treated?

    There will be a science - not to mindlessly execute commands from the Internet, and especially not to change the rights of system directories. What does whoami give out? - Enikeyschik
  • @ Enikeyshch gives user name - Aleksandr Chernya
  • And groups ? Is Ruth on the list? And sudo? - Enikeyschik
  • @ Enikeyshchik chernya2010 root sudo - Aleksandr Chernya 2:22 pm
  • Try deluser chernya2010 root , it will remove you from the root group. Then it will be necessary to log out and log in again. - Enikeyschik
