在 ubuntu 20.04 LTS 上无法安装 postgis

当我尝试使用以下命令安装 postgis 时：

sudo apt install postgresql-12-postgis-2.5

我遇到了一个错误：

The following packages have unmet dependencies:
 postgresql-12-postgis-2.5 : Depends: libgdal20 (>= 2.0.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

然后，当我尝试安装 libgdal20 时，我遇到了更多依赖问题

The following packages have unmet dependencies:
 libgdal20 : Depends: gdal-data (>= 2.2.3+dfsg-2) but it is not going to be installed
             Depends: libhdf5-100 but it is not going to be installed
             Depends: libnetcdf13 (>= 4.0.1) but it is not going to be installed
             Depends: libogdi3.2 (>= 3.2.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

有人可以指导我如何正确安装 postgis 吗？

更新

这是我的结果sudo apt update。后面跟着很多行警告，如下所示Target .... is configured multiple times in /etc/apt/sources.list:53 and /etc/apt/sources.list：

答案1

首先删除现有的存储库，您有一个来自 Bionic 的存储库，这就是导致问题的根源。假设它位于/etc/apt/sources.list.d/pgdg.list。

sudo rm /etc/apt/sources.list.d/pgdg.list

现在为您的系统添加正确的存储库。

echo "deb http://apt.postgresql.org/pub/repos/apt/ focal-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt update
sudo apt install postgresql-12-postgis-2.5

答案2

Lido 的答案也帮助我在 Ubuntu 18（带有 PostgreSQL 10）上安装了 Postgis，但我必须从 Debian 存储库安装软件包 libjson-c4 和 libgcc-s1
