Hi,

I can see 153 updates has been succeeded: http://prntscr.com/r5algy

So I think this is issues with some customers. 

First, let's try deactivate all plugins and try it again.

If it works, you can re-activate the plugins and do rest step ( update plugins )

If it doesn't work, it seems your hosting has been limited the upload max file size value - it makes the update can't be extract the update from the theme and caused this issue - check more here ( it's the same for update themes ):

If it still doesn't work - let's send me your hosting account ( hosting URL, username and password ) - in a PRIVATE REPLY and I will update it help you.

Best Regards,
