I installed m2.0.2 last week. Every new day that I log into the Admin Panel I need to resolve this error "One or more of the Cache Types are invalidated: Page Cache."
Is there a way to have this error resolved systematically and permanently rather me having to do it manually on the days I login to the backend?
It is not an "error", so you can just leave it unresolved.
The cache will be updated automatically by cron.
This is not error message, it means the cache is dirty and require a refresh. This may happen because of change in catalog price rule, product updates etc.

Sorry to have classified the message as an error @Dmitry_Fedyuk. To my intuition, when I see a big yellow background message such as this one, it screams out "error". I'll call it "alert".
This alert happens most every time I do something in the backend and then remains on each and every admin panel page.
When will the alert get updated by cron?
Why doesn't Magento just handle this programmatically?
Thanks @muk_t. Is there anyway to have Magento automatically refresh this? Why do I need to get the big yellow alert that remains on every screen throughout my experience in the backend setting up my store?
It is a Magento 2 usability problem.
Report it in the issue tracker, and it will be fixed: https://github.com/magento/magento2/issues
