Change system-wide "default" admin profile?

[Steven_G]

Last week I was experimenting with some bleeding edge pulse audio / HDMI stuff and something got fouled, bad.

Long story short I *think* I tracked it back to a corrupted permission in the home folder of the user I created at install (user 1) and for the life of me I couldn't get it fixed.

I ended up creating a new user and migrating *everything* from user 1 to user 2.

After lots of config and touble shooting I think I've solved every problem but 1:

When I use "deep" GUI tools like synaptic or users and groups they ask for the password of user 1 instead of user 2.

How do I tell the system that user 1 is no longer the default admin profile and that user 2 is now the default admin so I can delete the old corrupted user profile?

Replace User1 with User2 in /etc/sudoers file. Make sure not to edit anything else. Use visudo to edit sudoers file.

sudo visudo

You can edit /etc/sudoers file using any other text editor but using visudo is highly recommended. visudo checks the syntax of the file and not allow you to save it if there is bad syntax.

Ok thanks for the tip. I'll check when I get home (work / memory /senile). But I thought I did that already?

I don't think you have edited sudoers file. If you replace User1 with User2 in sudoers, there is no way you can use User1's password for administrative tasks.

[Steven_G]

Like I said: work /memory/senile.

Now, thinking about it, I *think* I might have both user 1 and user 2 in sudoers. I think I left the old in so I could su between them and have sudo powers on both profiles as I worked to migrate everything.

Is there like an order of placement preference for who is default? I ask because if they're both still in there then they're listed:

User2
User1

Is the last one in the list the "default" or is User1 still default because I haven't removed it from the file yet?

[Steven_G]

Actually, I just checked and I was right the first time. User2 is the only one at the bottom of the file when I open sudo visudo. Where else can I look?

Could you post the contents of /etc/sudoers file here?

And now I've really screwed myself. I'm mostly a GUI guy. I tired disabling the User1 profile in users and groups. So now I'm locked out of synaptic, user and groups, updates, ect because they are still asking for the User1 password.

Until I get this fixed how do I re-enable the User1 profile from the command line?

[Steven_G]

OK, I found

passwd -u username

and unlocked User1 profile so I can now perform GUI admin functions again. But, for the life of me I can't figure out how to get User1 to stop being default admin. I even tried changing User2 (bella) to UID:GID 1000:1000 and User1 (nancy) to 1003:1003. In users and groups I've also "demoted" nancy from an admin profile to a user profile.

But, somewhere in the system she's still listed as the default admin profile.

It looks like User1 is in sudo group and User2 is not. Execute id command as User1 and User2. Check if there is any difference in Groups.
Add User2 in sudo Group. You can do it in GUI as well as through command line.

sudo usermod -a -G sudo user2
