Debian 9 では PPA を使用しないでください。次の説明に従って適切なリポジトリを使用してください。オンドレイREADME.txt:
sudo apt-get -y install apt-transport-https lsb-release ca-certificates
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sudo sh -c 'echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
sudo apt-get update
php7.1-gdこれにより、Debian 9で満たす依存関係をインストールできます。
