I'm having problems upgrading MAgento 2 (Current version 2.0.7). When i try to upgrade I get the following error:

Check Component Dependency
We found conflicting component dependencies. Hide detail

For additional assistance, see component dependency help .

My cron job is setup as follows:

* * * * * /usr/bin/php /var/www/html/magento/bin/magento cron:run | grep -v "Ran jobs by schedule" >> /var/www/html/magento/var/log/magento.cron.log
* * * * * /usr/bin/php /var/www/html/magento/update/cron.php >> /var/www/html/magento/var/log/update.cron.log
* * * * * /usr/bin/php /var/www/html/magento/bin/magento setup:cron:run >> /var/www/html/magento/var/log/setup.cron.log

I have searched for hours upon hours for a solution but can't find a solution. Any ideas on how to fix the problem?
