Here's a guide for getting "Ubuntu-like sudo behaviour": Create the new sudo rule: Code: root echo "user ALL=(ALL) ALL" > /etc/sudoers.d/custom-user.sudoers update-sudoers Set user password: Code: passwd user After this You can close the terminal and uninstall the rootsh package. Or just remove it using: Code: apt-get remove rootsh Close the terminal and open a new one or exit out of the root shell using 'exit' or Ctrl-D. To become root now type (enter Your 'user' password): Code: sudo su - (Doing it this way there is no need to run sudo before commands if You've switched to root first) Or if You just want to run a single command as root type (enter Your 'user' password): Code: sudo <command> Oh, and Merry X-Mas BTW...
root echo "user ALL=(ALL) ALL" > /etc/sudoers.d/custom-user.sudoers update-sudoers
passwd user
apt-get remove rootsh
sudo su -
sudo <command>
