Ubuntu
shadow package

Administrator account without a password.

Asked by Sickofguessing

Installed Ubuntu 11.10 on a disc I burned on friday with a fresh install on a new 2tb hard drive. It was running great but when I was trying to turn off the need to input the password for every download I created an account that needed no password but when I turned on my computer the next day it asked for a password and wont sign in with a blank password box or with anything else in it.
I did the common step by going through grub but after the passwd command and changing the password it comes up with 'Authentication token manipulation error" and somthing like failed to change password. I look around and no-one has a fix that helps me in my particular instance although others are similer.
I tried to boot my live cd to reinstall and even tried using my new windows 7 disc to install over Ubuntu to at least have a computer to use but both instances just load up the installed partition and now im stuck with a locked computer on a Guest account.

I have tried to use TTy1 but it needs a login and password
I have tried passwdI have tried the kernel- or somthing like that to change it that a guide said to type ;rw init-/bin/bash/' but that does not even do a single thing other than crashing ubuntu and rebooting.
I have seen somthing about mounting the cd but I have no idea how as the offical ubuntu section on lost password says to boot up live cd then mount it but not exactly how that happens.

I have no idea what to do.-Thanks

If you don´t find any other option then reinstall.During install select manual way ( or I think now is something else) and select partition with ubuntu and install on it.You can even delete it first and then mark it as /root and ext4 and check format box.

I would LOVE to re-install but I have no idea how to do this on Ubuntu. Quite embarrassing really.

If https://help.ubuntu.com/community/LostPassword doesn't work then please post a reply describing exactly what happens (or if you have already tried to convey that information to us, please try to clarify so we better understand). You might also try working from the similar instructions at http://www.psychocats.net/ubuntu/resetpassword.

If we cannot get any of that to work then I can provide detailed instructions for booting from a live CD, mounting your Ubuntu partition, chrooting into it, and resetting the password that way. (Even that would typically take considerably less time than reinstalling from scratch, and though it's more technical than reinstalling, the technical burden on you would be as small as possible--I can provide specific instructions for obtaining the necessary system-specific information, then walk you through the process.)

In the end I found my BIOS would not detect my CD drive correctly so a total reinstall of Ubuntu fixed everything, Thanks for the help.

@Eliah Kagen -Also note that the reason I could not reinstall was because of the faulted BIOS thanks anyway

I'm sorry to hear about the trouble you're having with your Ubuntu installation. It sounds like a frustrating situation, especially since you've tried several different solutions without success. Have you considered reaching out to the Ubuntu community for help? They may be able to provide you with some specific advice or troubleshooting steps to try. Additionally, if you're unable to access your account or reset your password, you could try booting into recovery mode to see if that helps resolve the issue. I hope you're able to find a solution soon. For more visit : https://garagedoorrepairvirginiabeach.net/common-garage-door-opener-problems-and-how-to-fix-them/
