在Ubuntu 16.04 Xenial上安装PostGis

Question

我想在ubuntu xenial 16.04上安装Postgresql 9.6的PostGis 2.3，with：

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt trusty-pgdg main" >> /etc/apt/sources.list'
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

然后安装postgis：

sudo apt-get install postgresql-9.6-postgis-2.3

但这返回：

The following packages have unmet dependencies:
postgis : Depends: libgdal1h (>= 1.9.0) but it is not installable
          Depends: libgeos-c1 (>= 3.4.2) but it is not installable
          Depends: liblwgeom-2.3-0 (>= 2.0.0) but it is not going to be installed

Answer 1

我知道这是较晚的，但是对于那些遇到这个问题的人，请尝试使用16.04

时，设置Xenial-PGDG而不是Trusty-PGDG

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt xenial-pgdg main" >> /etc/apt/sources.list' 
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add - 
sudo apt-get update
