答案1
不要在 Debian 9 上使用 PPA，请使用适当的存储库，如中所述翁德雷吉的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
这将允许您安装php7.1-gdDebian 9 中可以满足的依赖项。
