What version are you using? I have implemented checks so that one cannot remove itself from the admin group if he's the last admin years ago. Could you check they don't work?
Anyway, Ubuntu doesn't use the gnome-system-tools by default anymore, so maybe you think about gnome-control-center? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-system-tools in Ubuntu. https://bugs.launchpad.net/bugs/907452 Title: Switching user account type from Admin to Standard in a case of single user. Status in One Hundred Paper Cuts: Invalid Status in “gnome-system-tools” package in Ubuntu: New Bug description: If there is no other admin accounts in the system, it is very difficult to switch account back. This is because we can't "sudo" anymore. The only way to fix it is entering single user mode and editing /etc/group. I think there should be some warning at least if the user is the only administrator in the system and he tries to become "Standard" user (by accident in my case).
