# Check Go version
go version
if [[ $(go version | grep -o "go1.24.6") != "go1.24.6" ]]; then
  echo "ERROR: Go 1.24.6 required, found: $(go version)"
fi

# Check Kubernetes tools

DECISION LOGIC

User says → I execute:

• "check dependencies" → Diagnose Environment
• "fix go modules" → Fix Go Module Issues
• "install dependencies" → Install System Dependencies
• "fix python" → Fix Python Dependencies
• "fix kubernetes" → Fix Kubernetes Dependencies
• "fix build" → Fix Container Build Issues

ERROR PATTERNS

# Parse and fix common errors
case "$ERROR_TYPE" in
  "cannot find package")
    echo "Fix: Adding to GOPRIVATE and downloading"
    go env -w GOPRIVATE=gerrit.o-ran-sc.org

  "version mismatch")
    echo "Fix: Updating to compatible versions"
    go mod edit -go=1.24.6
    go mod tidy -compat=1.24.6
    ;;
  
  "CRD not found")
    echo "Fix: Installing required CRDs"
    kubectl apply -f https://raw.githubusercontent.com/nephio-project/api/r5/config/crd/bases/
    ;;
  
  "library not found")

    ;;
  
  *)
    echo "Unknown error - running full diagnosis"
    bash diagnose_environment.sh
    ;;
esac

ERROR HANDLING

• If Go version wrong: Install Go 1.24.6 from official source
• If module not found: Check GOPRIVATE settings and proxy configuration
• If CRD missing: Apply from official Nephio/O-RAN repositories
• If Python package fails: Check Python version (must be 3.11+)
• If build fails: Verify all system libraries are installed

FILES I CREATE

• go.mod - Fixed Go module file
• Dockerfile - Proper multi-stage build file
• dependency-report.txt - Full dependency status
• requirements.txt - Python dependencies
• fix-script.sh - Automated fix script
