【问题描述】：

我已经安装了 PostgreSQL 9.5 并且正在使用 Debian 8.5 jessie。

The following packages have unmet dependencies: 
  postgresql-9.5-postgis-2.2 : Depends: libgdal1h (>= 1.9.0) but it is not going to be installed
                               Depends: liblwgeom-2.2-5 (>= 2.2.0) but it is not going to be installed
                               Depends: libsfcgal1 (>= 1.2.0) but it is not going to be installed

已经尝试过修复：

有人知道我应该怎么做才能走得更远吗？谢谢你

【解决方案1】：

好的。如果还有人遇到问题 - 我从 /etc/apt/preferences.d/ 中删除了 testing.pref 并删除了

deb http://ftp.debian.org/debian stretch main contrib non-free
deb-src http://ftp.debian.org/debian stretch main contrib non-free\

来自 sources.list，因此所有依赖项都降级为稳定的 jessie 版本
