Can't upgrade to latest version

I can’t upgrade to 2.7.0.beta8.

I run:

cd /var/discourse
git pull
./launcher rebuild app

It finishes successfully but not upgraded from 2.7.0.beta5

Can you check your app.yml file around line 35

cd /var/discourse
nano containers/app.yml

By default, it is on tests-passed, maybe you are on a specific commit or another branch

  ## Which Git revision should this container use? (default: tests-passed)
  #version: tests-passed

shows the same lines you wrote
