expert install user not a sudoer if root password given

It happens the same to me.

Dapper 6.06 beta2 i386 expert install is not working (well, sudo is not working).

I do an expert install on a PC. at installation time I give root password 'aaa', and create normal user account named 'acastan' with password 'bbb'.

/etc/sudoers and /etc/group files are misconfigured.

not "%admin " line in /etc/sudoers
not "admin" group in /etc/groups

this is the /etc/sudoers in the expert installation (see no "%admin" line at the end of the file):

-------------------

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
# Host alias specification

# User alias specification

# Cmnd alias specification

# Defaults

Defaults !lecture,tty_tickets,!fqdn

# User privilege specification
root ALL=(ALL) ALL

This has been brought up as a bug several times but has been listed as the intentional actions for the package

It means that the install is broken.
During install, instructions are given onscreen of actions that should be carried out during the OEM configuration phase. These actions don't work if followed because of this 'intentional' feature of the package.
So either there is a bug in the sudo package OR a mistake in the install instructions.

I don't see why the OEM user can't be added to the sudoers list and then removed by oem-config-prepare. There isn't a security issue and it can't be hard to write a script to remove them from the sudoers file.

Pete should not have closed this bug.

Apologies

/var/lib/dpkg/info/passwd.config includes these lines:

    if ! root_password; then
     sudoers_admin_group
     addgroup --system admin >/dev/null 2>&1 || true
     adduser "$USER" admin >/dev/null 2>&1 || true
    fi

basically, if you've set a root password, then it won't make the 'admin' group, or allow the admin group to use sudo to become root.

This in turn makes the GNOME menu entries for 'synaptic' and other admin programs not work, since they use 'gksudo'.

Do you have references for the other bugs where this has been brought up? This bug should be marked as a duplicate of them.

/var/lib/dpkg/info/passwd.config is no longer used in Dapper; the corresponding code is in user-setup.

Please do not mark this bug as a duplicate of any other bug; it is already a duplicate of bug 16139.

Oh, sigh, you actually just marked this bug as a duplicate of bug 16139. I'd prefer it to stay separate, as it's now a clean bug documenting just the issue that the expert user isn't a sudoer if the root password is given, rather than a grab-bag of other partially-fixed issues.

This bug also occurs if you don't actually create an initial user during the expert install -- the admin group is not created, and not given sudo access.
