I'm using Ubuntu 14.04 and like it very much but I can't update anything because I forgot my password and authentication is required. This is a home computer and I am a single user who doesn't even care about passwords.
I've done a lot of research and have tried the routine password changing steps .. recovery mode .. mount -rw -0 remount / etc
.. which got me “authentication token manipulation error password unchanged
. I’ve read the threads and tried the fixes with no luck.
You know in the beginning I might have set my password before I set the time/date and another guy who did that got the same message and claimed that that had caused his problem. He fixed his by deleting the encrypted password in the /etc/shadow
file and then doing thesudo passwd username
fix to create a new password. He never said how he deleted the encrypted password and that is where I am stuck trying his fix. When I look at cat /etc/shadow
I can see the encrypted password right next to my user name but I can't get into the field to delete it.
Where and how do I delete this password so that I can create a new one.
Any help would be greatly appreciated.
Thanks
