Cannot bypass the password?

Question

I forgot my Ubuntu password. I followed the steps given on your sites and I almost reached the end, but then my computer said:

passwd: authentication token manipulation error

I tried to do it again many times but it comes to the same result. I cannot open my account.

Answer 1

There is a Authentication Token Manipulation Error when trying to update user's password in Ubuntu because your root filesystem was mounted as read only, which prevents changing the password.

To mount it read/write, enter the command:

mount -o remount,rw /
