Dear proj and cdo specialists,
I am trying to install cdo (climate data operator) on Ubuntu 18.04. I have gdal 3.0.0 and proj 7.0.1 installed. There are some missing dependencies which cannot be installed. It boils down to the point where it says libproj13 is missing and cannot be installed.
What I have done so far. Install cdo, it depends libmagplus3v5, this depends libgeotiff2, this depends libproj13, this can't be installed. See here:
root@eosao34:~# apt-get install cdo

So apparently i have libproj12, libproj15 and libproj19 installed.
I have the feeling that libprojXX is delivered with a specific version of proj. Because I have tried installing different versions of proj from apt package manager and now see all the different versions of libprojXX. But not libproj13. Unfortunately I cannot find a source which explains how to install libproj13 or which libprojXX is linked to which proj. I have tested installing cdo on other VMs where libproj13 is present. There it works.
My question is: How do I get libproj13 installed so that cdo runs?
The easiest option is to install CDO using conda (https://anaconda.org/conda-forge/cdo).
However, I have a set of bash scripts for installing CDO and dependencies from source. This will presumably solve your problems: https://github.com/r4ecology/nctoolkit/tree/master/cdo_installers
