CI Failure: Terraform executable not found in GitHub Actions

[shebang42]

Description

The CI pipeline is failing due to Terraform not being found in the PATH on GitHub Actions runners. This is caused by recent changes to GitHub's Ubuntu runner images where certain packages, including Terraform, have been removed from the default image.

Error message:

Downloaded model: gen/models/Cisco-IOS-XR-um-if-ipv6-cfg.yang
main.go:41: running "terraform": exec: "terraform": executable file not found in $PATH

Root Cause

According to GitHub's changelog, they are migrating ubuntu-latest to Ubuntu 24.04 and have reduced the number of pre-installed packages to maintain their SLA for free disk space.

Proposed Solution

Add the official HashiCorp setup-terraform action to the workflow:

- name: Setup Terraform
  uses: hashicorp/setup-terraform@v2
  with:
    terraform_version: '1.5.0'  # or preferred version

Additional Context

• This change affects all workflows running on the new Ubuntu 24.04 images
• The migration of ubuntu-latest to Ubuntu 24.04 started on December 5, 2024
• Similar issues might occur with other previously pre-installed tools
