runsh: Total unexpected failed scenarios throughout the test run:
cliEncryption/encryption.feature:27

That fails because the scenario does decrypt-all. To do that occ command it needs to turn on singleuser mode. If we did that via the testing app, then the testing app (and all other API endpoints) get disabled, and the test cannot turn off singleuser mode. So the test does the occ commands directly as \system() calls. The test-runner has PHP 8.1, and we know the oC10 does not support that yet. So the occ commands fail. This is a situation where the test-runner must use a PHP version that is supported by the system-under-test. I can't think of a "simple/reasonable" way to get around that.

  Scenario: Update of minor version of an app                                         # /drone/src/tests/acceptance/features/cliManageApps/appUpgrade.feature:10
    Give app "updatetest" with version "2.0.0" has been put in dir "apps"            # AppManagementContext::appHasBeenPutInDir()
    And app "updatetest" has been enabled                                             # FeatureContext::appHasBeenDisabled()
    And app "updatetest" has been disabled                                            # FeatureContext::appHasBeenDisabled()
    When the administrator puts app "updatetest" with version "2.1.0" in dir "apps"   # AppManagementContext::putAppInDir()
    And the administrator enables app "updatetest"                                    # FeatureContext::adminEnablesOrDisablesApp()
    And the administrator runs upgrade routines on local server using the occ command # OccContext::theAdministratorRunsUpgradeRoutinesOnLocalServerUsingTheOccCommand()

    Then the installed version of "updatetest" should be "2.1.0"                      # AppManagementContext::assertInstalledVersionOfAppIs()
      Return code not found after executing 'occ config:app:get updatetest installed_version --no-ansi'. Is the testing app installed and enabled?

This is another situation where a local occ command has to be done. After creating and enabling the new app, the scenario needs to do occ upgrade. At this point the testing app (and other oC10 apps and API endpoints) are not responding. So occ upgrade has to be done directly, and not through the testing app.

Everything else passes, so that is good.
