How to fix no available releases match the given constraints in Terraform

TerraformINTERMEDIATEHIGHUpdated Dec 30, 2025· 135 views

This error occurs when Terraform cannot find a provider version that satisfies all version constraints in your configuration and modules. Conflicting constraints between modules or outdated local plugins typically cause this issue.

Quick fix

Fixes no available releases match the given constraints

terraform providers
  1. Run terraform providers to identify all version constraints
  2. Check for outdated local plugins cache
  3. Identify conflicting module versions
  4. Pin module versions to resolve conflicts
terraform — error

no available releases match the given constraints

What this error means

This error happens during terraform init when Terraform evaluates version constraints for providers and modules. Terraform requires that all version constraints be satisfied simultaneously—if module A requires provider version >=6.0.0 and module B requires <6.0.0, no version exists that satisfies both, causing this error. The error message often displays the conflicting constraints, such as "no available releases match the given constraints 5.99.1, 6.0.0" or "~> 2.12.1, 2.25.2", showing the impossible requirement set.

Typical symptoms

  • terraform init fails during provider version resolution
  • Error message shows conflicting version constraints
  • Working configuration suddenly fails after module or provider updates
  • Different team members see different errors (due to local plugin cache differences)

Common causes

  1. Different modules require incompatible provider versions (e.g., module A requires >=6.0, module B requires <6.0)
  2. Unpinned module versions allowing automatic upgrades that introduce conflicting provider requirements
  3. Outdated or stale ~/.terraform.d/plugins directory with incompatible cached provider versions
  4. Newly added module or updated module dependency requirements conflict with existing constraints
  5. Pessimistic version constraints (e.g., ~> 5.14) that prevent necessary major version upgrades

How to fix "no available releases match the given constraints"

1Run terraform providers to identify all version constraints

First, understand what constraints are being applied. Run:

bash
terraform providers

This shows all provider dependencies and their required versions across your configuration and all modules. Look for the provider that has conflicting constraints.

2Check for outdated local plugins cache

An outdated ~/.terraform.d/plugins directory can cause version resolution failures. Move it temporarily to rule this out:

bash
mv ~/.terraform.d/plugins ~/.terraform.d/plugins.old

Then retry terraform init. If this works, the issue was cached plugins. Keep the plugins.old directory removed or clean it out.

3Identify conflicting module versions

Look at the error message—it shows which constraints conflict. Find the modules that are imposing these constraints. Check:

1. Your root module's required_providers block
2. Each module call in your configuration (grep -r "required_providers" in modules/)
3. The modules/ directory for sub-module constraints

The terraform providers command output shows which module is requiring which version.

4Pin module versions to resolve conflicts

Once you identify conflicting modules, pin their versions to ones that are compatible with your provider requirements.

For example, if your root config requires aws ~> 5.0 but a new module requires aws >= 6.0, pin the module to an earlier version:

hcl
module "networking" {
  source  = "terraform-aws-modules/vpc/aws"
  version = "5.1.0"  # Pin to a version compatible with your provider
  # ... config
}

Then run terraform init -upgrade to re-evaluate constraints.

5Update provider version constraints to allow compatibility

Alternatively, relax your provider version constraints to allow the versions required by modules. For example, change from ~> 5.0 to >= 5.0, < 7.0.

hcl
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 5.0, < 7.0"  # Allows more flexibility
    }
  }
}

Run terraform init -upgrade after making changes:

bash
terraform init -upgrade
6Commit .terraform.lock.hcl to prevent version drift

Once init succeeds, ensure your .terraform.lock.hcl file is committed to version control. This file locks all provider versions, preventing different team members from experiencing different constraint resolution results.

bash
git add .terraform.lock.hcl
git commit -m "Lock provider versions"

Always commit this file so the entire team uses identical versions.

Advanced notes

Understanding version constraints is crucial for Terraform projects with dependencies. The pessimistic constraint operator (~>) is useful but can create inflexible requirements. For example, ~> 5.14 allows 5.14.x and 5.15.x but not 6.0.0, which can cause compatibility issues if dependencies need major versions.

When working with modules from the Terraform Registry, always check their provider version requirements before using them. Use terraform providers to visualize the full dependency tree. For large infrastructure projects with many modules, consider using version ranges that provide flexibility while maintaining stability: >= X.Y.0, < (X+1).0.0.
