Error checking latest version: %s

Error message

Error checking latest version: %s

What it means

Thrown by `terraform version` when the configured CheckFunc (a best-effort latest-version check) returns a non-nil error. CheckFunc is the callback that queries the version service; on failure the error is appended as a diagnostic but the command still exits 0 — this is informational, not fatal. The %s is the network/parse error.

Solutions

1. Ignore it — this error does not block terraform; the version still prints.
2. If in an air-gapped environment, suppress it by configuring checkpoint to be disabled (CHECKPOINT_DISABLE=1 / TF_CLI_VERSION_CHECK env) if your build exposes that.
3. Verify network egress to the version-check host and proxy settings if you want the update notice.
4. Retry later if the version-check service had a transient outage.

Example fix

# before
terraform version
# Terraform v1.x.y
# Error checking latest version: Get "...": dial tcp: i/o timeout

# after (suppress / allow offline use)
CHECKPOINT_DISABLE=1 terraform version

// this error is non-fatal; treat the version check as best-effort.
// Disable the check in air-gapped environments:
//   CHECKPOINT_DISABLE=1

// best-effort version check: ignore failures
if _, err := c.CheckFunc(); err != nil {
    log.Printf("version check skipped: %v", err) // continue, do not block
}

When it happens

Trigger: Running `terraform version` (or `terraform version -json`) when CheckFunc fails: no network, blocked registry host, proxy/DNS issues, or the version-check endpoint returned an unparseable response.

Common situations: Air-gapped/offline environments; egress firewall blocking the version-check host; corporate proxy/MITM; misconfigured TF_CLI_ env; transient registry outage.
