Can not delete new user which use "adduser"

[freet15]

A post from Cjacker show me that bug, To review this issue, you can doing follow this steps:

1, sudo adduser test ---- then you got a new user named test (also password)

2, use Alt + Ctrl + F2 change to a terminal login as test.

3, logoff from this terminal

4, back to your main terminal or X, and use deluser / userdel to delete user "test", then, here we get is a system warning:
        "can`t delete user test: user is currently log in "

this maybe a bug , maybe a policies for something , maybe system does not update wtmp status unhesitating :)

Thanks for your bug report. I tried to duplicate this error, but failed to succeed. Is anybody else able to reproduce this?

[freet15 (freet15)]

 I forget to post the version of ubuntu . I got this bug from ubuntu 8.04.

[Nick Ellery (nick.ellery)]

Yes, I attempted to reproduce this in Hardy, but I did not succeed.

[freet15 (freet15)]

Hmm....
    all test must be use command line , you did not use "Users
Administration Tool" ?! But, In my system and some confrere`s, this issue

Yes, I did this via command line following your instructions to reproduce. We will just wait and see if anybody else can duplicate it.

[Danilo Penna Queiroz (daniloqueiroz)]

i've reproduced this bug.

[Dereck Wonnacott (dereck)]

I attempted to reproduce this, but I also did not succeed.

As an idea, try your test and then attach the output of ps aux > ps_aux.log

[Dereck Wonnacott (dereck)]

a second run makes me say.... indeed, I also can confirm.

Seems like enough people are able to reproduce this bug.

After logging out test, can you please test with "ps -U test -a" whether there are still any processes from user 'test' left?

there are none

Bumping this bug, as it's in effect.

The user I'm trying to delete is "rtc" and I'm logged in as "watcher". Here's some output:

[WickedMonkey (primate-wickedmonkey)]

Looks like I've run into this bug as well. Ubuntu server 10.04, 64 bit (installed from an iso image downloaded 27/01/2012 from ubuntu.com).

I logged in to my box using my admin account and then ran 'sudo su' to change to root. To create the [new user] account I:
1. Created linux user [new user] ('useradd [new user]').
2. Created samba user [new user] ('smbpasswd -a [new user]').
3. Wanted to test the account so I 'su [new user]' then 'exit' back to my admin/root shell.
4. I realised I'd mis-type the [new user] username so deleted samba account ('smbpasswd -x [new user]') and tried to delete the linux account 'userdel [new user]'. Got error 'userdel: user [new user] is currently logged in'. I exited the terminal ssh session and logged back in but got same error.

'ps -U [new user] -a' gives me:

  PID TTY TIME CMD
 2837 pts/0 00:00:00 su
 2838 pts/0 00:00:00 bash
 2860 pts/0 00:00:00 ps

If I kill these processes, my admin/root session ends and when I log back in I get the same 'userdel: user [new user] is currently logged in' error. Running 'who' doesn't show [new user] logged in, just the admin account I'm logged in as.

[WickedMonkey (primate-wickedmonkey)]

Just rebooted my problem box and can run 'userdel ...' with no error. Rebooting is not always an option on a server though.

[Rodney Beede (business2008+launchpad)]

I have a similar issue and it seems to be related to duplicate uid in /etc/passwd for the affected account.
