Error NU5026 dll to be packed was not found

Question

I am getting following error :

create_nuget
The file '/home/runner/work/MyNugetPackage/MyNugetPackage/MyNugetPackage/bin/Release/net6.0/MyNugetPackage.dll' to be packed was not found on disk.

This is my YAML file :

    branches:
      - '*'          # Run the workflow for all pull requests
  release:

I have tried to run command to generate release folder as well in local because it was earlier complaining about it but now it is failing , I am using GitHub actions.

It is a Nuget packages that is supposed to be compatible with .NET 6

I am not sure what am I missing here.

Endomorph

Is this path /home/runner/work/MyNugetPackage/MyNugetPackage/MyNugetPackage/bin/Release/net6.0/MyNugetPackage.dll valid? Have you checked the build logs? Is that DLL being generated? If yes, include those logs in your question. – Abort

Yes this is exact error generated by Github Actions – Endomorph

Have you looked at learn.microsoft.com/en-us/nuget/reference/errors-and-warnings/… and ruled out all the potential causes mentioned here? – Abort

Answer 1

Encountered similar issue. There is a thing in your csproj that may trigger that. Make sure to remove this:

<GeneratePackageOnBuild>true</GeneratePackageOnBuild>

source

The error line (french) was:

NuGet.Build.Tasks.Pack.targets(221,5): error NU5026: Le fichier 'C:...\bin\Release\net48....dll' à compresser est introuvable sur le disque.

Answer 2

I also encountered this error. In my case the issue was that I had set the project up to target multiple frameworks:

<TargetFrameworks>net45;net452;net46;net462;net47;net472;net48;net481;net6.0-windows;net8.0-windows</TargetFrameworks>

however I missed removing the original target framework line:

<TargetFramework>net8.0</TargetFramework>

Once I removed the TargetFramework declaration, the build completed without issue.
