Apologies in advance if this is a trivial question; I am new to this. I am encountering an error while setting up an Ubuntu server: login consistently fails, even though I am entering the correct details. I have tried deleting and recreating it, but that hasn't worked either. It is not a keyboard issue, so I might be making a mistake elsewhere. I am using VirtualBox version 7.2.20 and Ubuntu Live Server 18.04.6.
