我正在尝试在运行 Stretch 的 Debian 服务器上安装 PostGIS。我毫无问题地在其上安装了 PostgreSQL，但是当我尝试安装软件包时postgresql-9.6-postgis-2.3，最新的可用软件包 apt-get 会尝试安装大量 X 和不相关的软件包：
sudo apt install --no-install-recommends postgresql-9.6-postgis-2.3

知道这是怎么回事吗？我不想在我的服务器上安装任何与 X 相关的软件包，而且我试图避免手动编译。
答案1
libsfcgal1安装之前，先从 stretch-backports安装包postgresql-9.6-postgis-2.3。
罪魁祸首包是libsfcgal1，它依赖于libopenscenegraph100v5。
依赖链的相关部分是：
postgresql-9.6-postgis-2.3依赖于取决于libsfcgal1这取决于libopenscenegraph100v5这取决于libav*包裹，libqt*包裹，libxine2等等。
