Host build interrupt error

When I check the log file, it appears to me that there aren’t any errors but obv I’m not sure.

Here are the last few lines of the log file (I can send the whole thing to you if necessary):

The weird thing is the package files have been created. I can see them when I go to:
/wp-admin/admin.php?page=duplicator

But due to that error message, I’m concerned that the package is corrupt or has issues. I use duplicator to backup my website, so I need to be confident that this is working.

The website runs on a VPS that I have full access to via WHM. I recently upgraded server to PHP 7.2.16 and I’m pretty sure this is the first time I’ve used duplicator since that upgrade.

I get this error every time (tested 4 times)

Thanks in advance for your help. 🙂
