groupdel: cannot remove the primary group of user 'administrator'
43,477
This is documented in the man page. From man groupdel
:
You may not remove the primary group of any existing user. You must remove the user before you remove the group.
So you need to make the primary group of user administrator
something other than pro1
and then you should be able to remove group pro1
.
Example:
$ sudo groupdel foobar
groupdel: cannot remove the primary group of user 'foobar'
$ sudo usermod -g foo foobar ## Change the primary group of user "foobar" from "foobar" to "foo"
$ sudo groupdel foobar ## Done

When I try to delete the group
pro1
(groupdel pro1
) it shows the error:groupdel: cannot remove the primary group of user 'administrator'
And when I create new user from AD server, the user's default group is
pro1
.How can I fix this problem? Thanks.

roadkiller180 over 8 yearsI tried to change administrator's primary group,but it can not work. $usermod -g test administrator $usermod: user 'administrator' does not exist in /etc/passwd $usermod: failed to unlock /etc/shadow 'administrator' even not exist in /etc/passwd.

heemayl over 8 years@roadkiller180 yeah, there could be configurations leading to this..why are the UIDs>10000 ? Also whats the output of
grep 'administrator' /etc/passwd
? -
roadkiller180 over 8 yearsgrep 'administrator' /etc/passwd output: postgres:*:111:120:PostgreSQLadministrator,,,:/var/lib/postgresql:/bin/bash

roadkiller180 over 8 yearsI set UID range in smb.conf from 10000-20000 at the first time,and now change to 50000-60000,so you can see some UID like 50002,50001 as i mentioned in the previous comment.

heemayl over 8 years@roadkiller180 This behavior that you can't remove users that are not in
/etc/passwd
is a known bug.. bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/988072 ..as you are using samba you are affected by this..also if you have any conf related issues with samba like the GID issue you have mentioned, you should ask that as a new question..
