500 error on 'Illegal' version string

[icarr-fsg]

Attempting to restore a solution which references swashbuckle.aspnetcore causes a 500 error to be returned from klondike. This aborts the Visual studio build process requiring the Klondike package source to be removed to continue.

The problem appears to relate to a version of this package with a tag: 1.0.0--rc1 (Note double hyphen)

The failing URL is:

http://nuget-klondike:8080/api/odata/FindPackagesById()?id=%27Swashbuckle.AspNetCore%27

Note: the project references 1.0.0 (not 1.0.0--rc1) and I can't find any other reference to the 'invalid' version.

For posteriority: Klondike seems to not support new versions of NuGet which is the root cause for many versioning issues (due to support for .NET Standard 2.0, semantic versioning etc.).

Had this error, too.
This works:
NuGet.exe install Swashbuckle.AspNetCore -Source https://packages.nuget.org/v1/FeedService.svc/
This works not:
NuGet.exe install Swashbuckle.AspNetCore -Source http://localhost:8080/api/odata
