Drupal 8.x

I have a Drupal 6 app that I want to upgrade to 8.1.1 so I'm following the instructions at Drupal.org.
Drupal core 8.1.1, php 5.6.19, ubuntu 14.04

I first try drush using the latest version available (8.0.5) but the module is not found when I attempt to run drush migrate-upgrade. I gave up on it since there seems to be a problem.

Hello DrupaLovers,

I want to install Bootstrap on my Drupal 8. Now: I can install it. When I set it to default, it says, it was set to default. BUT then when I refresh my site it throws a 500 error.

We're having a problem with caching that is affecting anonymous users.

We have a form in a block that when the user fills out the form, they are able to download a PDF. We hide the block on pages where we don't want this PDF download form to appear. Ideally the block is hidden, if no PDF is available for a particular page, but the block is being cached and displayed regardless the of the actual page. This only is a problem for anonymous users. Logged in users do not have the problem of the seemingly cached PDF download blocks appearing on the wrong pages.
