Thanks for your report, @mausch

Could you try using latest dotnet SDK (5.0.300) ? https://dotnet.microsoft.com/download/dotnet/5.0

Which OS are you using?

Are you setting SHOW_NUGET_STACK environment variable, as documented here ?

[mausch]

Same exception with 5.0.300 :

docker run --rm -it mcr.microsoft.com/dotnet/sdk:5.0.300-buster-slim dotnet nuget kk ''

I'm not setting SHOW_NUGET_STACK (or NUGET_SHOW_STACK according to the docs?)

[dominoFire]

Yes, NUGET_SHOW_STACK is the correct environment variable. Sorry for the confusion.
