Adding a user to the sudoers list in Ubuntu
Stop using root for administrative tasks. Here is how to add a new user to the sudoers list in Ubuntu.
When adding a new user on a Linux system, it's not automatically added to the list of sudoers, which is what's required for the user to have root privileges.
If you need to add a new user with root privileges, then do the following.
Add a new user by running the
adduser command followed by the username.
# adduser rasmus Adding user `rasmus' ... Adding new group `rasmus' (1000) ... Adding new user `rasmus' (1000) with group `rasmus' ... Creating home directory `/home/rasmus' ... Copying files from `/etc/skel' ... Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing the user information for rasmus Enter the new value, or press ENTER for the default Full Name : Room Number : Work Phone : Home Phone : Other : Is the information correct? [Y/n] y
Now add the newly added user to the group
# usermod -aG sudo rasmus
That's it. This works on Ubuntu because the group sudo is listed in the sudoers file.
%sudo ALL=(ALL) ALL
If you log on as the newly created user, you can try to run something like the following in order to test that it works.
$ sudo apt-get update
