@ddo88:

1. Are you using Linux or Mac build agent? I've only tested on windows and it has been long time ago. Very few people were downloading this extension, so I'm not sure whether it makes sense to support it.

2. I recommend you the official way to restore Libman packages as part of dotnet build command using <PackageReference Include="Microsoft.Web.LibraryManager.Build" Version="...." />, see restore-files-during-build

EDIT: An alternative come to my mind: You might install the Microsoft.Web.LibraryManager.Cli global tool as a separate step, see: https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/dotnet-core?view=azure-devops&tabs=dotnetfive#build-your-project

  steps:
  - task: DotNetCoreCLI@2
    displayName: 'Install Libman'
    inputs:
      command: custom
      custom: tool
      arguments: 'install -g Microsoft.Web.LibraryManager.Cli'

and then invoke libman restore using Command Line task or simmilar

Yes was on linux agent
