You didn't indicate where you downloaded that, or whose instructions you followed to "successfully [install] Cloudera in Oracle VM VirtualBox Manager". But I can tell you that the screen shot you've posted is not an error.
At this point in time or later, you (or anyone else reading this) should not be attempting to run the QuickStart VM on VirtualBox. The Cloudera Quickstart VM has been discontinued and has been obsolete for some time now, as it was based on CDH 5.13 which reached end of support in the Fall of 2020. Note that Cloudera never supported the QuickStart VM officially and again, it's been obsolete for years now.
Cloudera's current Enterprise Data Platform is Cloudera Data Platform (CDP), which in it's on-premises "form factor" was released back on November 22, 2019, over two and a half years ago. CDP supersedes CDH as Cloudera's data platform offering. The on-premises "form factor" of CDP is now called CDP Private Cloud. You can download a trial version of CDP Private Cloud to install on-premises here: CDP Private Cloud 60-day free trial.
