The process 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' failed with exit code 1

Question

my problem is that I have a project created in .net core 2.2, the problem is that I am trying to deploy it with azure pipelines but when using the dotnet restore it fails continuously and ends the construction.

The error it returns is the following:

2020-11-21T20:17:30.4639428Z ##[error]**Error: The process 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' failed with exit code 1**

2020-11-21T20:17:30.4655465Z **Info: Azure Pipelines hosted agents have been updated to contain .Net Core 3.x (3.1) SDK/Runtime along with 2.1. Unless you have locked down a SDK version for your project(s), 3.x SDK might be picked up which might have breaking behavior as compared to previous versions.**

I have tried to install version 2.2 to be used in the process before the restore, I have tried using the nuget.config and the global.json.I leave here the .yml that I have used to see if someone can give me a hand.

  inputs:
    version: 2.2.x
    includePreviewVersions: true
    performMultiLevelLookup: true

I used your pipeline to test it on minimal solution and it works. Can you try to do the same? — Krzysztof Madej

I've tested with a .net core 2.2 project using the following yaml file, and got successful result.

trigger:
- master

pool:
  vmImage: 'windows-latest'

steps:
  - task: UseDotNet@2
    inputs:
      version: '2.2.x'
      includePreviewVersions: true
      performMultiLevelLookup: true
  - task: DotNetCoreCLI@2
    inputs:
      command: 'restore'
      projects: '**/*.csproj'

In order to narrow down the issue, I'd like to suggest you:

Create a simple .net core 2.2 project and push to DevOps, create a pipeline for this project to see whether you can reproduce this issue.
Clone the project to local, and run dotnet restore command locally to see how's the result.
