Hi I had a friend put unbuntu on my computer and when I try to update it it says I have to put in a administrative password I didn't put one in I need a password to update the unbuntu programing Sincerely David

David,

When you install any linux distro, it always need a "administrative password" or "root password" to set in administrative tasks.
So, your friend, when he installed your ubuntu, he should must set a password. There's no other way.

So, call your friend and ask him for the password. If he dont remembers, you will need to reinstall ubuntu.

I think you must simply change your user password...

To discover your user and 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

Hope this helps
