I've got

clone_git_repo_on

breakage too which I completely don't understand:

An error occurred in a `before(:suite)` hook.
Failure/Error:
  clone_git_repo_on(host, '/etc/puppetlabs/code/environments/production/modules',
                    name: 'scl',
                    path: '<https://github.com/lsst-it/puppet-scl>',
                    rev: 'production')
NoMethodError:
  undefined method `clone_git_repo_on' for main:Object
  
    clone_git_repo_on(host, '/etc/puppetlabs/code/environments/production/modules',
    ^^^^^^^^^^^^^^^^^

It appears to still be in beaker-puppet: https://github.com/voxpupuli/beaker-puppet/blob/master/lib/beaker-puppet/install_utils/foss_utils.rb#L188
