Description of problem:
While testing the Capsule upgrade from 6.7 to 6.8 via foreman-maintain (6.8 feature), I bumped into an installer issue which seems to be solved here: https://github.com/theforeman/foreman-installer/pull/472

However, on Capsule 6.7 I do still face it, although the foreman-installer-2.1.0-0.3.1.rc2 is present and I can see the fix as well:

# satellite-maintain upgrade list-versions
6.8
# satellite-maintain upgrade run --assumeyes --target-version=6.8 --whitelist="repositories-validate,repositories-setup,disk-performance"
Checking for new version of satellite-maintain...
Nothing to update, can't find new version of satellite-maintain.
Running Checks before upgrading to Capsule 6.8
================================================================================
Skipping pre_upgrade_checks phase as it was already run before.
To enforce to run the phase, use `upgrade run --phase pre_upgrade_checks`



Running Procedures before migrating to Capsule 6.8
================================================================================
Skipping pre_migrations phase as it was already run before.
To enforce to run the phase, use `upgrade run --phase pre_migrations`



Running preparation steps required to run the next scenarios
================================================================================
Check if tooling for package locking is installed:                    [OK]

Scenario [Migration scripts to Capsule 6.8] failed.

The following steps ended up in failing state:

  [installer-upgrade]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="installer-upgrade"


# rpm -qa | grep installer
satellite-installer-6.8.0.5-1.el7sat.noarch
foreman-installer-katello-2.1.0-0.3.1.rc2.el7sat.noarch
foreman-installer-2.1.0-0.3.1.rc2.el7sat.noarch
ansiblerole-satellite-receptor-installer-0.6.6-1.el7sat.noarch


# cat /usr/share/foreman-installer/hooks/pre_validations/31-puppet-agent-oauth.rb
unless app_value(:noop)
  if File.exist?('/opt/puppetlabs/puppet/bin/ruby') && execute_command("rpm -q puppet-agent-oauth", false, false)
    unless execute_command("/opt/puppetlabs/puppet/bin/ruby -e \"require 'oauth'\"", false, false)
      execute("yum -y reinstall puppet-agent-oauth", false, true)
    end
  end
end


Running 'yum reinstall puppet-agent-oauth' as a workaround works, but we will need some fix for Capsule as well.

Thank you.


Version-Release number of selected component (if applicable):
foreman-installer-2.1.0-0.3.1.rc2


How reproducible:
always


Steps to Reproduce:
1. Install a 6.7 capsule, register it to a Satellite
2. Add and enable Satellite 6.8 repos
3. Run # satellite-maintain upgrade run --assumeyes --target-version=6.8 --whitelist="repositories-validate,repositories-setup,disk-performance"


Actual results:
installer::upgrade fails


Expected results:
successful run
