NuGet on the Docker

Is there a way get NuGet on a linux based Docker image?

I tried this:

ARG PAT

FROM microsoft/dotnet:sdk AS build
WORKDIR /app

COPY src/IdentityServer/ ./

# the annoying NuGet installation
RUN wget -q https://packages.microsoft.com/config/ubuntu/16.04/packages-microsoft-prod.deb
RUN dpkg -i packages-microsoft-prod.deb
RUN apt-get install nuget
RUN nuget sources add -name yyyy-source https://xxxx.pkgs.visualstudio.com/_packaging/yyyy/nuget/v3/index.json -username dummy -password ${PAT}
RUN dotnet publish -c Release -o out

FROM microsoft/dotnet:aspnetcore-runtime AS runtime
WORKDIR /app
COPY --from=build /app/out ./
ENTRYPOINT ["dotnet", "IdentityServer.dll"]

I get this:
