Hello, noob here.
Am on Ubuntu 11.10 and somehow it says my password is incorrect every time I try to authenticate something. Updates, new apps or whatever, nothing goes because I keep getting the password wrong.
I gave up trying to guess and just want to reset it so I have access again. Is this possible and if yes, how to go about it?

Okay, so my sister gave me her laptop. It's got 12.10 on it. I'm trying to install Python 3.3 on it but my sister forgot her password so I can't perform any adminsitrative tasks, like installing programs. What should I do?
12.04 cannot reset password
- date: April 11, 2013
I'm not sure what happened, but the password I have written down is not working as Admin password. (I may have changed it in a frustrated session trying to get the internet to work at my sister's place.)
I followed instructions at http://www.psychocats.net/ubuntu/resetpassword, but this is what happens:
I am in the [email protected]
: directory [my root]
When I type in
passwd username [Yes, I use the real username]
the system responds with
command not found
The file also suggest to remount the boot directory:
mount -o rw,remount /
The system responds with the same prompt and no change.
I am stuck because I cannot make changes to my system and cannot connect to the internet here at my son's place.
Would really appreciate suggestions.

Reset your Windows password, edit the Windows Registry from Ubuntu
location: ubuntuforums.com - date: July 10, 2010
THE MAIN GOAL OF THIS TOPIC IS TO SHOW AN ABILITY OF WINDOWS REGISTRY EDITING BUT NOT PASSWORD RESETTING ONLY. IT WAS CREATED AFTER READING OF THE FOLLOWING AT THE FORUM, WHERE THE QUESTIONS STILL WITHOUT ANSWERS INFACT:
In connection with the Windows viruses and impossibility to start regedit or Windows in whole, sometimes Windows users need to edit the registry from outside. I've found, so far, the only utility in Linux chntpw, which was originally designed to reset passwords, and then acquired the registry editing ability.
Editing the registry:
1. Boot from a LiveCD or install a second system Ubuntu.
2. Install chntpw utility:
sudo apt-get install chntpw
3. Mount Windows partition:
Find the Windows partition:
$ sudo fdisk -l
Assume it is on /dev/sda2. Next s
Howto: Reset root password of a VM
location: ubuntuforums.com - date: December 29, 2010
I just wasted a couple hours of my life trying to reset the root password of a virtual machine. Trying to boot into Single user mode, just would not work. Eventually, I found a quite trivial method. VMware Player can mount the VM disk on the host and then you can edit the /etc/shadow file at your leisure.
Run VMware Player and Open the VM.
Click Edit Virtual Machine Settings, Hard Disk, Utilities (at the bottom) has an entry for Mount Disk.
Create a mount point:
$ sudo mkdir /mnt/vm
Now mount the Vm disk on this point.
Enter the mount point and go to /etc:
$ sudo vi /etc/shadow
Delete the root password between the first two colons and save the file:
Now unmount the VM disk and boot normally. Open a terminal in the VM and set the root password:
[SOLVED] unable to reset root password in RHEL6
- date: January 4, 2012
I'm unable to reset root password from Single User Mode in RHEL6.
'passwd' command takes me to the next line without prompting for 'New Password'.
/]# passwd root
I even tried it after remounting / in rw mode, but no change in the response to the passwd command.
The command 'passwd' is working to change the password of the current logged in user. So, I suppose the binary may not be corrupted.
Any help is greatly appreciated.
