Bug#691890: general: sudoers problem

[Y <oliver1199@web.de>]

Package: general
Severity: grave
Tags: d-i
Justification: renders package unusable



-- System Information:
Debian Release: 6.0.6
  APT prefers stable-updates
  APT policy: (500, 'stable-updates'), (500, 'stable')
Architecture: amd64 (x86_64)

Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores)
Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash

I can not install any software, because if I type 'sudo su' and type the correct Password I get only:
"<USER> is not in the sudoers file.  This incident will be reported."

I am the Admin, but I cannot do anything to personalyse my KDE Debian System.

I also cannot edit the sudoers file, witch is empty, because I have not the
Privileges to edit/Save the file

Please send me help per e-mail

Thank you!

PS: I am sorry for my bad english, I am german
