Atlas ubuntu/xenial64 password

Question

Today I upgrant my vagrantbox from ubuntu/trusty64 to ubuntu/xenial64
but I found that username changed to ubuntu and I don't konw the password
I try "vagrant" as default password but It's wrong,Someone can tell me the default password of ubuntu/xenial64?

Answer 1

username: vagrant
password: vagrant

but that's for ubuntu 14.04
I guess maybe it's
username: ubuntu
password: ubuntu

that's my guess
if not working, then u can change or set it by yourself

using

vagrant up
vagrant ssh 

into your box.

then

sudo passwd <username>

will do the trick..
