When I do bundle update I get:

Bundler could not find compatible versions for gem "ruby":
In Gemfile:
ruby (~> 3.0.0)

thredded (~> 0.16.13) was resolved to 0.16.16, which depends on
  ruby (~> 2.3)

I looked online and someone said to do bundle update rails but when I do I get this error:

Bundler could not find compatible versions for gem "activemodel":
In Gemfile:
active_model_serializers was resolved to 0.10.10, which depends on
activemodel (>= 4.1, < 6.1)

challonge-api was resolved to 0.2.0, which depends on
  activeresource was resolved to 5.1.0, which depends on

activemodel-serializers-xml (~> 1.0) was resolved to 1.0.2, which
depends on
activemodel (> 5.x)

challonge-api was resolved to 0.2.0, which depends on
  activeresource was resolved to 5.1.0, which depends on
    activemodel (>= 5.0, < 7)

carrierwave was resolved to 2.0.2, which depends on
  activemodel (>= 5.0.0)

rails (= 6.1.2.1) was resolved to 6.1.2.1, which depends on
  activemodel (= 6.1.2.1)

Any ideas what I need to do?

I am new to Ruby on Rails I have followed this tutorial:https://www.crondose.com/2016/12/guide-integrating-omniauth-rails-5-facebook-login-feature/

It lets me reach the login and even accept the connection on the facebook side. I thought it might have been the gem folder but it matches perfectly with the one in the tutorial. Which is this:

source 'https://rubygems.org'
