Upgrade from v2.1.6 to latest 2.2.0

[webtent]

I've tried to upgrade using the Web Setup Wizard and get the dreaded 'Update pending' even after I try to kick the cron jobs. Then I try the command line approach I've seen in posts and its asking for credentials. I try to use the only credentials I have, my Magento account and it says they're invalid. How can I get this upgrade done?

[root@li1244-190 magento]# php composer.phar require magento/product-community-edition 2.2.0 --no-update

    Authentication required (repo.magento.com):
      Username: webmaster@webtent.com
      Password:


  [Composer\Downloader\TransportException]
  Invalid credentials for 'https://repo.magento.com/packages.json', aborting.

Nevermind about the credentials, I found the access keys and that worked, but getting an error below. When I used the Web Setup Wizard, it passed the readiness check. How can I handle these dependency issues:

[root@li1244-190 magento]# php /usr/local/bin/composer require magento/product-community-edition 2.2.0
./composer.json has been updated
