failed to get updates: %w

Error message

failed to get updates: %w

What it means

getUpdates compares each menu addon against installed channel versions via addon.GetRequiredUpdates. A per-addon error aborts the whole comparison and applyMenu wraps it as 'failed to get updates: %w', aborting before any changes are made.

Solutions

1. Identify the offending addon from the wrapped cause
2. Fix or delete the in-cluster addon object with the malformed version/annotation
3. Ensure the channel's addon.yaml declares valid semver versions
4. Re-run apply after correcting in-cluster state

for name, cv := range channelVersions {
	if cv != nil && cv.Version != "" {
		if _, err := semver.Parse(cv.Version); err != nil {
			return fmt.Errorf("addon %q has unparsable version %q; fix in-cluster state", name, cv.Version)
		}
	}
}

func hasValidVersion(cv *channels.ChannelVersion) bool {
	if cv == nil || cv.Version == "" {
		return true
	}
	_, err := semver.Parse(cv.Version)
	return err == nil
}

updates, needUpdates, err := getUpdates(ctx, menu, k8sClient, cmClient, channelVersions)
if err != nil {
	return fmt.Errorf("aborting apply before changes; fix addon state: %w", err)
}

When it happens

Trigger: During applyMenu, one addon's GetRequiredUpdates errors — usually fetching the installed addon object or parsing its version annotation.

Common situations: Corrupt or unparsable version annotation left by an older kOps version, missing/modified addon resource in-cluster, cert-manager client or API read errors.
