I am a new Ubuntu user with 12.04 lts and stepped away from my computer for a month and forgot my password.

Using this forum I attempted to reset my password using a root line upon booting in grub, I followed instructions to find I was getting results that no one else had gotten. asking for reset options that I didn't understand how to use, it said the the argument was invalid, So I found a way to delete my encrypted password in a nano list. I was able to log in but Sudo still seems to recognize a Password and even thought my user account profile says "none" after password I can't seem to do anything.

I don't know what else to do, hopefully it can be fixed. the long explanation was to show my inexperience and give light to any mistakes made.

Thank you

  • askubuntu.com/questions/24006/… this was one of them the rest were the same with simple variations, but this has the post with the nano instructions "drastic measures"

Reset to default

  1. Boot from live CD/USB
  2. Mount partition that has the issue at /tmp
  3. Chroot into /tmp
  4. Do sudo visudo -f /etc/sudoers.d/USERNAME
  5. Add USERNAME ALL=(ALL) NOPASSWD: ALL to file
  6. Remove live usb, boot normally
  7. Do sudo passwd root, this will set root pass

Might work, haven't tried it in a while, but sounds right.

  • I was sure it was going to work but after rebooting sudo passwd root prompted for a password.

  • Did you put your username in place of USERNAME?

  • Yes, minding caps as well.
