Lost password

Asked by Rocky Exline on 2012-10-19

A friend just put Ubuntu 12.1 on his laptop, and he now has lost admin privledges. He does not remember putting a password in but it asks for one now. Can someone tell me how to reset the password for him?

Tried that and it comes up, "authentication token manipulation error" password unchanged

You get that with a read only file system. Run:

mount -o remount,force,rw /

Then retry

No luck there either. There is a space between mount and -o and between -o and remount right? Still got the same message anyway.

Try again the same guide (from Recovery) and forget about the mount command.

First click the NETWORK option. This option will mount your drive in read-write mode , you will see the confirmation window.

Then Click ROOT and give the command to change your password

passwd <your username>

Confirm twice the new password and write something easy.

okay I did that. Loaded quite a bit of things and ended up with "network-manager start/running, process 994"
Froze right there. Or at least went to a blinking cursor.

Thanks Nick. Took a while, but that worked.
