bash - How to push nuget package in GitHub actions

Question

I am trying to use GitHub actions to generate a NuGet package from my project and push it to the (private) GitHub registry.

My script ([NAME] fields redacted):

name: Update NuGet

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest

    name: Update NuGet 
    steps:
      - uses: actions/checkout@master
      - uses: actions/setup-dotnet@v1
        with:
          dotnet-version: '2.2.105'
      - name: Package Release
        run: |  
          cd [SOLUTION_FOLDER]
          dotnet pack -c Release -o out
      - name: Publish Nuget to GitHub registry
        run: dotnet nuget push ./[SOLUTION_FOLDER]/[PROJECT_FOLDER]/out/$(ls ./[SOLUTION_FOLDER]/[PROJECT_FOLDER]/out) -s https://nuget.pkg.github.com/[USERNAME]/index.json -k ${GITHUB_TOKEN}  
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} 

Log output:

info :   PUT https://nuget.pkg.github.com/[USERNAME]/

Second Update: I got an answer in the GitHub issue from jcansdale that says (haven't tested this):

Support for the dotnet nuget push --api-key option has now been added to GitHub Packages. For some reason this works consistently, but using basic auth (password in nuget.config file) fails randomly!

Example:

  - name: Publish Nuget to GitHub registry
    run: dotnet nuget push ./<project>/out/*.nupkg -k ${GITHUB_TOKEN} -s https://nuget.pkg.github.com/<organization>/index.json --skip-duplicate --no-symbols 
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Update: Based on Dids answer on GitHub my configuration works now like this:

name: NuGet Generation

on:
  push:
    branches:
      - master
  pull_request:
    types: [closed]
    branches:
      - master

jobs:
  build:
    runs-on: ubuntu-18.04
    name: Update NuGet package
    steps:

      - name: Checkout repository
        uses: actions/checkout@v1

      - name: Setup .NET Core @ Latest
        uses: actions/setup-dotnet@v1
        with:
          source-url: https://nuget.pkg.github.com/<organization>/index.json
        env:
          NUGET_AUTH_TOKEN: ${{secrets.GITHUB_TOKEN}}        
          
      - name: Build solution and generate NuGet package
        run: |  
          cd <project>
          dotnet pack -c Release -o out  

      - name: Push generated package to GitHub registry
        run: dotnet nuget push ./<project>/out/*.nupkg --skip-duplicate --no-symbols true

Note: At the time of writing I needed to use --no-symbols true instead of --no-symbols to prevent exceptions in the dotnet NuGet client.

Old answer:

I switched to the Windows image and got it to work based on the example of @anangaur. This is my final code:

name: NuGet Generation

on:
  push:
    branches:
      - master

jobs:
  build:
    runs-on: windows-latest
    name: Update NuGet 
    steps:

      - name: Checkout repository
        uses: actions/checkout@master

#  latest image has .NET already installed!
#      - name: Setup .NET environment
#        uses: actions/setup-dotnet@v1
#        with:
#          dotnet-version: '2.2.105' 
          
      - name: Build solution and generate NuGet package
        run: |  
          cd SOLUTION_FOLDER
          dotnet pack -c Release -o out  

      - name: Install NuGet client
        uses: warrenbuckley/Setup-Nuget@v1
        
      - name: Add private GitHub registry to NuGet
        run: nuget sources add -name "GPR" -Source https://nuget.pkg.github.com/ORGANIZATION_NAME/index.json -Username ORGANIZATION_NAME -Password ${{ secrets.GITHUB_TOKEN }}
        
      - name: Push generated package to GitHub registry
        run: nuget push .SOLUTION_FOLDERPROJECT_FOLDERout*.nupkg -Source "GPR" -SkipDuplicate
