I installed Ubuntu Core using these instructions, and added a user. But when I try to add the user to the admin group, it says the group does not exist. What do I do?

PS I had to install sudo, however it made no difference.

On traditional Linux/Unix systems there is no "admin" group, such group was widely introduced for desktop usage. If you really need an admin group on a core system (you may not needed), you will need to create it manually:

groupadd admin -g 120

  • Then if do not have my user in the admin group, how will do the tasks that require admin privileges? Log in as root? – Oxwivi Oct 24 '11 at 06:56

  • No, you install sudo and set it up allowing commands from a user/group. Anyway I gave you the answer how to create the group, if you really need it :) – João Pinto Oct 24 '11 at 18:41
  • According to this link: https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/893842 Ubuntu now uses the 'sudo' group as the admin one. Therefore if you want to perform admin actions, your user will require to join the 'sudo' group. – Javier López Sep 07 '13 at 06:04
