Introduction

This Knowledge Base (KB) article addresses an issue encountered after upgrading Bitbucket version to 8.18.0. Specifically, Terraform is unable to download a module, resulting in the following error:

fatal: could not read Username for 'http://bitbucket_server_url': No such device or address

 

Problem

Post-upgrade, Terraform fails to download modules from Bitbucket, leading to authentication issues. The error message indicates that Terraform is attempting to read a username for HTTP authentication, which is failing.

Prerequisites (if applicable)

  • Access to the Terraform Enterprise (TFE) environment.
  • Administrative access to the Bitbucket server for configuration changes.
  • Bitbucket Server 8.18.0

Cause

  • Module hosted bitbucket version prior to 8.18.0 was publicly accessible but with bitbucket version 8.18.0 "anonymous public access" was disabled by default
  • Terraform module source is configured to used http

Overview of possible solutions (if applicable)

  • Configure SSH for module source URLs in Terraform.
  • Ensure port 22 is open for SSH communication between TFE and the Bitbucket server.
  • Add ssh key with appropriate access to module repository.

Solution:

  • Check SSH Connectivity: Check and open the network communication between bitbucket(VCS) and TFE.

  • Update the Terraform Configuration: Edit the Terraform configuration file to update the module source URL to use SSH.

          Module source should look like below :

git::ssh://git@code.xxx.com/scm/tfe/terraform-aws-xxx-xxx-vpc.git?ref=v0.4.2.1
  • Add the ssh-key with required access of module repository into TFE. 

Outcome

After implementing the above solutions, Terraform should be able to download the modules using SSH, thereby resolving the authentication issue.
