On a Macbook Air laptop, on 10.10.3, I'm trying to upgrade to 10.10.4.
The first time, the system downloaded the file. After the download, I had a message saying (I'm translating form french): "download of some updates did not finish; they can't be installed".
Since then, the system update shows with the "update" button, but the system does not redownload the file, I see a notification saying the system will reboot, but actually it will display the above error message.
How can I force the upgrade?

This should be easy to resolve.
