Cake build NuGetPush throws permission denied

Question

I'm building my .NET Core app in Travis CI using Cake script, when it comes to

var d = new DirectoryInfo(packageOutputPath.ToString());
var Files = d.GetFiles("*.nupkg").Select(x => new FilePath(x.FullName));

var key = EnvironmentVariable("NugetKey");

NuGetPush(Files, new NuGetPushSettings {
 Source = Variables.NugetSource,
 ApiKey = key

command I get:

An error occurred when executing task 'PushPackage'.
Error: One or more errors occurred. (Permission denied)
    Permission denied

My .travis.yml file:

sudo: required                

language: csharp              
mono: none                    
dotnet: 2.1.402               
before_install:
  - chmod +x build.sh         

script:
  - ./build.sh --Target="PushPackage"

I have tried replacing - ./build.sh --Target="PushPackage" with - sudo bash build.sh --Target="PushPackage" but this did not help. Any suggestions why I'm getting this error?

build.sh file was builded according to this. Whole repo is here.

You should be using the DotNetCoreNuGetPush alias when using the .NET CLI, NuGetPush requires nuget.exe.

Example:

DirectoryPath packageOutputPath = MakeAbsolute(Directory("./nuget/"));

var settings = new DotNetCoreNuGetPushSettings
{
     Source = "https://www.example.com/nugetfeed",
     ApiKey = "4003d786-cc37-4004-bfdf-c4f3e8ef9b3a"
};

foreach(var file in GetFiles($"{packageOutputPath}/*.nupkg"))
{
    DotNetCoreNuGetPush(file.FullPath, settings);
}
