Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

You can set a new password from recovery mode. Choose recovery mode from the boot menu and then issue the command "passwd username". Run "exit" to resume normal mode.

Chris,

I'm sorry I don't understand, what Lars proposed. What is the boot menu?

Thanh you,
Ruben

Many people get a menu when you first boot, ie before Ubuntu starts to load. Sometimes it says something about a grub menu, and that you have to click some button, maybe the delete key. (Sorry, I can't quite remember). You only have a few seconds to click. That is also the menu being talked about.

1 ---- ) First try this:

I don't remember user and password what i can do

You can do this: http://www.psychocats.net/ubuntu/resetpassword

or

To discover your user and restore (change) the password you can:

Start the pc the when you see the GRUB row...

Press ESC.

Press "e" for edit.

Highlight the line that begins kernel ………, and press "e"

Go to the very end of the line, add rw init=/bin/bash

press enter, then press "b" to boot your system.

Your system will boot up to a passwordless root shell.

Type in grep -i 1000 /etc/passwd

The system must show a row with your user name at the start of the row
for example:
danilo:x:1000:1000:ubuntu,,,:/home/danilo:/bin/bash

Here my user is danilo

Then to change your user password type in:

passwd username

or

passwd -d username

change username with your real user

Set your password.

Type in:

reboot

or

reboot -f

*******************************************
After restoring/change your password
*******************************************
2 ---- ) You strictly need to open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo dpkg --configure -a

give your user password when requested, you don't see nothing when you type it, then press enter.
-------------------------------------------------------------------

But to fully check and upgrade your system using terminal using command line,
open a Terminal from the menu Applications->Accessories->Terminal

Tip: right click with mouse on the terminal title caption and select the item "Always on Top" doing this you will force the terminal window to stay on top of the other windows and you will find very easy to copy single row from this web page into the terminal...
Something more about using the terminal https://help.ubuntu.com/community/UsingTheTerminal

Then type or better copy and paste a row a time then press enter:
(Tip: select the single row to copy then right click into the terminal and to quick paste click with middle button of mouse )

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

then please reboot your system, type

sudo reboot

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps
