Getting this error when trying to update

Problem: package gdl-0.9.8-6.fc29.20180919gitd892ee5.x86_64 requires libgrib_api.so.1()(64bit), but none of the providers can be installed
- package eccodes-2.9.2-1.fc29.x86_64 obsoletes grib_api < 1.27.0-2 provided by grib_api-1.27.0-1.fc29.x86_64
- cannot install the best update candidate for package grib_api-1.27.0-1.fc29.x86_64
- cannot install the best update candidate for package gdl-0.9.8-6.fc29.20180919gitd892ee5.x86_64

Yes, this is known. gdl needs to be rebuild using eccodes. I filed a pull-request to do just that, see: https://src.fedoraproject.org/rpms/gdl/pull-requests, but the maintainter seems to not have had time to work on it. If this is important to you I suggest you file a bug against gdl. It will not be possible to have eccodes and gdl+grib_api installed at the same time until this is resolved.
