SuiteCRM Update

I have SuiteCRM on 7.10.7 and i am trying to update for the latest version. But when i verify the system they show me that the Parsing XML is not available. My OS is Ubuntu 18.04 and php version is 7.02
Someone can help me?

I don’t understand this part

they show me that the Parsing XML is not available

Where is this error showing? What is the exact text of the error?

On the Upgrade Wizard, as in the attached image.

I already solved the problem with ‘sudo apt-get install php7.2-xml’
