I have configured an Azure DevOps pipeline. When I try to run NuGetToolInstaller, I received ERR:self signed certificate in certificate chain. What is the solution to this error?

If you use Azure DevOps service, and your organization is secured with a firewall or proxy server, you need to add certain IP addresses and domain URLs to the Allow list by following this doc: Allowed address lists and network connections. And if you use self-hosted agents, please follow this doc: Run a self-hosted agent behind a web proxy to configure your agent.

If you use on-premise Azure DevOps Server, please refer to this doc: Run the agent with a self-signed certificate to check this issue.

In addition, if you recently changed your account, you could refer to this thread to check if its solution works for your issue.

BTW, you could review debug logs to diagnose pipeline issues.

In my case this was caused by the fact that I was using a proxy which in turns uses custom root SSL certificates. I fixed this in Windows Server by exporting the root certificates needed in a PEM file, which should look something like:

GlobalSign Root CA

Save this to a file, example c:\ca.pem Then set the environment variable:

set NODE_EXTRA_CA_CERTS=C:\ca.pem

Restart the ADO agent so that it picks up the new environment variable and then it should just work.

This is because the ADO tasks, and in particular the NuGetToolInstaller@1 task uses a versions of Node that does not picks up the certificates installed in the Windows certificate store. In this way we make node aware of the custom certificates.
