ImportError: libeccodes.so: cannot open shared object file: No such file or directory

Using conda with the conda forge channel to install python-eccodes on linux (RHEL and ubuntu), we noticed today that the importing eccodes crashes with an import error.

Minimal example:

conda install python-eccodes

That downloads and install

    package                    |            build
    ---------------------------|-----------------
    eccodes-2.19.0             |       hf05d9b7_1         4.0 MB  conda-forge
    python-eccodes-2020.06.0   |   py38hab2c0dc_1          94 KB  conda-forge
    ------------------------------------------------------------
                                           Total:         4.1 MB

And then:

We see here in github that there is a 2020.10 release, could it be that it didn't make it to conda-forge for some reason?

Note: rolling back to eccodes 2.18.0 fixes the problem.

Fixed when 2020.10 was uploaded on conda-forge
