Can't Execute Commands as sudo Nor Access Sudoers File in Mandriva 2010.1
 

Hi everybody, since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line. Any help will be greatly appreciated.

have you tried the command "su" to drop into root?

Actually, you'll need
the '-' gives you root's env inc $PATH; otherwise you retain your own even though logged in as root.
The cmd to configure sudo users is

visudo

as root etc..

Thank you lukav and chrism01, I'll try it and will report back.

Thank you all for your help. 'su -' worked great. I'm now studying 'vim tutorial' so I can learn to edit files. I really appreciate your help. Thanks again.
