在Ubuntu Xenial上安装postgresql-10-postgis-2.5时的依赖问题(16.04)

Question

在Ubuntu Xenial (16.04)上安装postgresql-10-postgis-2.5时，在2.5.3版本(几天前发布到PostgreSQL Apt Repo )之后会出现一些依赖问题。原因是现在的postgresql-10-postgis-2.5 (2.5.3+dfsg-2.pgdg16.04+1版本)需要libgeos-c1v5 (>= 3.7.0)，而libgeos-c1v5的最新版本是3.5.0-1ubuntu2 for Ubuntu Xenial (https://packages.ubuntu.com/search?keywords=libgeos-c1v5)。我可以升级到bionic (18.04LTS)，但同样的问题也存在，因为它带来了3.6.2版本。19.04目前对我来说不是一个选择。

有没有办法在Ubuntu Xenial (16.04)上使用apt安装libgeos-c1v5 >= 3.7.0或postgresql-10-postgis-2.5 2.5.2

在Docker容器上本地复制它的步骤如下：

docker run -it ubuntu:xenial /bin/bash

apt update
apt install -y curl

echo "deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main" > /etc/apt/sources.list.d/pgdg.list
curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -

apt update
apt install postgresql-10-postgis-2.5 postgresql-10-postgis-2.5-scripts

当我们尝试安装postgresql-9.6-postgis-2.5时，我们在Ubuntu 18上遇到了类似的问题。我们必须安装实验版本3.7才能让它工作。

libgeos-3.7.0_3.7.0-1_bionic0_amd64 libgeos-c1v5_3.7.0-1_bionic0_amd64.deb

https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-experimental/+build/15675841

然而，我不确定你是否可以在xenial上得到这个。

希望这能帮上忙，谢谢。

更新:我们现在已经在仿生库中发布了libgeos的更新版本，希望更新版本也能为xenial发布，谢谢。
