PostGIS 依赖冲突（ubuntu 14）

我问这在 SO 上，但现在我认为问题主要是包管理，并且属于这里。

根据原始帖子中可以找到的所有细节，我已经尝试过（sudo 被消除，因为是多余的）：

$ apt list | grep gdal | grep installed
gdal-bin/trusty,now 1.11.0+dfsg-1~exp2~trusty1 amd64 [installed]
libgdal1h/trusty,now 1.11.0+dfsg-1~exp2~trusty1 amd64 [installed,automatic]
$ apt-get purge gdal-bin
$ apt-get purge libdal1h
$ add-apt-repository ppa:ubuntugis/ppa
$ apt-get update
W: Failed to fetch http://ppa.launchpad.net/ubuntugis/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/ubuntugis/ppa/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

显然有些东西配置错误了...我不知道我这边该检查什么...

然后

$ fab vagrant.Provision # see the original question above for what this is doing at the linux level

这仍然会遇到完全相同的依赖性问题libdal1：libgdal1h

[localhost] sudo: DEBIAN_FRONTEND=noninteractive apt-get install --quiet --assume-yes postgresql-9.3-postgis-2.1

答案1

正如@saircot895 引导我发现的那样，问题在于存储库之间存在冲突。我提出的问题中没有看到具体细节，因为我没有深入研究用于设置相关虚拟 Ubuntu 盒的 Fabric 脚本。实际上，该脚本使用的是较旧的“Precise”版本作为 postgres 本身，但 postgis 使用的是较新的“Trusty”。将 postgres 安装（以及其余配置）更改为较新的版本解决了该问题。

答案2

我已经成功（没有任何损坏的依赖项）安装了postgresql-9.1-postgis-2.0。postgresql-9.1-postgis并且数据库运行正常。
