问题描述
亲爱的项目和CDO专家，
我正在尝试在Ubuntu 18.04上安装cdo（气候数据操作员）。我安装了gdal 3.0.0和proj 7.0.1。有些缺少的依赖项无法安装。归结为说libproj13丢失并且无法安装。
到目前为止我所做的。安装cdo，它取决于libmagplus3v5，这取决于libgeotiff2，这取决于libproj13，无法安装。看到这里：

Package libproj13 is not available,but is referred to by another package.
This may mean that the package is missing,has been obsoleted,or
is only available from another source
E: Package 'libproj13' has no installation candidate

当我搜索libproj1时。我明白了：

因此，显然我已经安装了libproj12，libproj15和libproj19。
我感觉libprojXX是随proj的特定版本一起提供的。因为我尝试从apt软件包管理器中安装不同版本的proj，现在可以看到所有不同版本的libprojXX。但不是libproj13。不幸的是，我找不到源来解释如何安装libproj13或哪个libprojXX链接到哪个proj。我已经测试过在存在libproj13的其他VM上安装cdo。在那里工作。
我的问题是： 如何安装libproj13以便cdo运行？
解决方法
最简单的选择是使用conda（https://anaconda.org/conda-forge/cdo）安装CDO。
但是，我有一组bash脚本，用于从源代码安装CDO和依赖项。大概可以解决您的问题：https://github.com/r4ecology/nctoolkit/tree/master/cdo_installers
