I go to System->Preferences->About authentication token manipulation Me and click on "Change Password". It then asks to authenticate the existing password. But it won't authenticate. I can log in just fine using the same password, but this won't authenticate it. I tried opening terminal and running passwd, sudo passwd, and even sudo passwd {user}, but all of them fail. This system has two users (both with sudo privileges), so even though I didn't really want to change the password on the other user, I logged in and tried all of the same steps from above. That was also unsuccessful. BTW, if I run sudo with another command, the passwords work fine, and I have no trouble logging in. I just can't change them. I am running 10.04. I've had Ubuntu on this computer since 8.04 (doing an in-place upgrade with each release), but this time I did a fresh install of the root folder, but kept the /home files in a different partition. ---- Laugh at life or life will laugh at you.
