Hi all,
For some reason my sudo password isn't working, even though I haven't changed the password. I tried to log into recovery mode and into root to change my password, but I get the error message "authentication token manipulation error," and I can't change the password.
I've checked the dumb stuff, like caps lock etc.
Any ideas??
Thanks.
sounds weirdQuote:

from the root prompt I just typed "passwd" then when prompted I entered a password, then again, then I received the error. I also tried "passwd user" where user is my regular user name. I don't think I tried "passwd root"Quote:

yes that's exactly where I got the info I used to do what I describe above. I logged into recovery mode, reached the root prompt, but when I try to change the password I get the authentication token error.Quote:

I log into recovery mode using the instructions above.
I select the "Drop to root" option
From root prompt, I type "passwd root"
I enter my password twice.
I get the error message Authentication token manipulation error
I'll try the emergency password reset now...Quote:

the emergency reset, i.e., booting from live cd to manually edit the shadow file, worked. Thanks for the help.Quote:
