Wordpress on Php7 not working as intended

I get an Error while activating the Plugin

Your PHP version does not support ZipArchive.

Unfortunately, we were unable to update your installed content types. You must manually download the update from H5P.org, and then upload it through the Upload Libraries section. If you need futher assistance, please file a support request or check out our forum.

Could solve it using

sudo apt-get install php-all-dev

I'm not familiar with php-all-dev, but yes, you are missing a component in PHP so it probably will install that component.
