If an error occurred while updating or installing macOS
How much Empty Space in on the drive ?
Suggest having at least 50 GB of Empty Space on the drive.
It will allow the Full Version ( about 12.xx GB ) to download, expand and then commence to install.
If there is Third Party Security Software installed - remove it.
It will interfere with both the download and installation process.
