I am a complete beginner at using Linux and Ubuntu.
I have installed Ubuntu 18.04.2 LTS in a VirtualBox VM.
I am now, some time after exploring how to use Ubuntu, getting message when I start Ubuntu.
I have (hopefully) attached a screenshot of the VM display taken by the Host system (not linux).
I do not know what to do about these messages or why they occur.
It is possible that they started after I had a host system crash.
