dompdf issues with 7.1

Just updated to latest version of Homeseated wiht php v7.1. But seems there are some issues with some of the packages like dompdf.

I already have services deployed as well and I'm not really an admin, so would like to just downgrade it to v7.0 for the time being.

sudo apt-get install php7.0 php7.0-mysql libapache2-mod-php7.0 php7.0-mcrypt php7.0-curl

Tried just doing a normal install but it's giving me a lot of not found errors for the packages. I'm using Homestead/Forge out of the box stuff.

Does anyone know how I an do this downgrade?
