--- Comment #6 from Robert-André Mauchin 🐧 zebob.m@gmail.com --- Wait there's more:
You need to use
%description %{common_description}
%gopkg <------
%prep %goprep
no self defined devel package.
Similarly the %files for devel shouldn't be defined manually but use instead:
%license LICENSE %doc CONTRIBUTING.md CHANGELOG.md %doc Documentation/* %{_bindir}/*
%gopkgfiles
