Password changed by upgrade

[customearl]

I installed Ubuntu on a Dell Optiplex GS.
I used wubi to install Ubuntu.
I then proceeded to update, and after update the administrator password was changed after reboot.
The original password was 8 letter password and now the password is a 5 letter password.
I found this out by going user accounts.
My experience is medium level with windows, and beginner in Ubuntu.
HELP!
Thank you.

Upgrades do not change your password.



The original password was 8 letter password and now the password is a 5 letter password.
I found this out by going user accounts.

User accounts simply shows five dots as a symbolic representation of a hidden password. There is nothing implied about the length of the password. My password is 12 characters long but I see the five dots as well. Are you still able to log into your account with your 8 character password?

My password seems to have changed after an upgrade too.
My old one won't let me do any admin-y stuff now & all I've done recently was a few upgrades.
Any way I can find out what the new/current password is?

You can reset your password by following these instructions (http://www.psychocats.net/ubuntu/resetpassword).

Hope that helps.

It didn't, until I found elsewhere that it should be mount -o remount,rw /
You put mount -o rw,remount / which didn't work for me - may have been my system, so might be worth putting it as an option too...

A fab little walkthrough though. Ta :)

There used to be an option on the recovery menu to remount drives as read-write. I don't know why they took it away because mount -o rw,remount / is hardly intuitive.

If I start getting weird behaviour on login after an update (especially with Wubi) I go defensive. Run chkdsk /f on windows partition (for wubi partition), then fsck the root.disk. Never heard of passwords changing... seems unlikely. More likely some corruption (but that's all speculation).
