• I am not able to add user in System Settings /User Accounts
  • I have tried installing the gnome-system-tools as suggested in the other post (linked in the end of this post)
  • I am logged in with my default admin user account

I have unlocked the System Settings/User accounts locker

I can fill all fields out after clicking the + button

After finished no new account is visible in the list, nor on log in screen

How can I add a new user account?

System information: elementary OS 0.3.2 Freya 64-bit MacBook (installed)

Best Regards M Edvardsen

  • Does your Create User button ever light up blue like this? i.imgur.com/bLFLj5T.png

  • Hi Lewis. Yes it does. I can create the account. But nothing seems to be created. Possibly in the "background" but not in the user list in gui and not on the login screen

  • tried terminal:--- cut -d: -f1 /etc/passwd the new user is not visible in the list either. Then tried: sudo adduser username system says something close to this: --- creates user "username" creates new group the_ same_ as_username (a number) creates new user "username" (a number) with group the_same_as_username useradd: existing lock file /etc/subuid.lock without a PID useradd: can not lock /etc/subuid; try again later. adduser: _"usr/sbin/useradd -d /home/_username_ -g _same as username_ -s /bin/bash -u _userid_ _username_" responded with error code 16. quits.

groups youruser
sudo useradd newuser -m -G x-group,y-group,z-group

Option -G assigns newuser to x, y and z groups, option -m creates the home of newuser

sudo passwd newuser
  • groups youruser generates a message: groups: user youruser does not exist

  • sudo useradd youruser -m -g yourgroup generates following error code: useradd: existing lock file /etc/subuid.lock without a PID useradd: can't lock /etc/subuid; try again later
