%users ALL=(ALL) ALL

Save and exit. Then, you need to add your name to the user group. Type the following command in a shell:

usermod -a -G users <your username>

From now, you can use the command sudo from your account.

  1. Under Fedora 21, it seems that this solution does not work anymore. A simpler solution found was as follows:

    edit /etc/sudoers and simply add :

    username ALL=(ALL) NOPASSWD: ALL

    replacing username with your login/username

  2. Under Fedora 23, no need to edit the /etc/sudoers file (which is read-oinly even for sudo user; if you really want to edit the sudoers file, use the tool called visudo). Just type this command in a shell:

    usermod your_login -a -G wheel

    and log off/ log in
