invalid password at login screen

[Dan Hoang]

Hi,

I'm new ubuntu user and I use Ubuntu 14.04 (Trusty Tahr)
<https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#Known_issues>  version.

I setup this OS yesterday (Nov, 19th, 2014) with login password is 123456

It's work correctly all day, and I install android-sdk for eclipse Luna
last night (run over night).

This morning (Nov, 20th, 2014) I can not log in to Ubuntu with message
"*invalid
password, pleas try again*" at login screen.

I logged as root user (recovery-mode) and change password to 123456 (please
find my attachment for detail)

I restart and login again, but I can not login. The message still: "*invalid
password, pleas try again*"

P/S: I installed Ubuntun in virtualBox 4.3.18, in Windows 7 host
