I am hoping someone can help me out here. For some reason my system has stopped letting me sudo. I can log into the machine just fine. When I attempt to install a package or sudo -i, I get asked for my password then get told that my account is not part of the sudoers file. There is only one user account on the machine.
I have attempted to use the recovery method off this site found here: How do I reset a lost administrative password?
When I try to change the password using Jorge's method I get an error: passwd: Authentication token manipulation error passwd: password unchanged
So I attempted the "drastic" measures:
mount -o remount,rw / nano -B /etc/shadow
and deleted my encrypted password. Saved the file and restarted the machine.
No password require, I hit return at the prompt. But I still cannot go to sudo. I tried sudo -i with the blank password and get: Sorry try again...
So I used passwd to change my password. It accepted the change. I then tried sudo -i and again I got user not a member of the sudoers group! I tried logging out and back in, it accepted my password to log in but not sudo -i or anything using sudo.
Please help me get my user back into the sudoers group. Thanks (not feeling all that great but hopeful..)
