error checking for required update: %v

Error message

error checking for required update: %v

What it means

getUpdates iterates the menu and calls addon.GetRequiredUpdates to compute how many updates each addon needs. Any per-addon error aborts the entire menu processing with 'error checking for required update: %v' (note %v, not %w). Called from applyMenu and tests.

Solutions

1. Identify the offending addon from the message
2. Correct or delete the in-cluster addon object with the invalid version
3. Ensure addon.yaml versions are valid semver
4. Re-run apply

if cv := channelVersions[addon.GetNamespace()+":"+addon.Name]; cv != nil {
	if _, err := semver.Parse(cv.Version); err != nil {
		return fmt.Errorf("installed addon version %q is not semver; fix before applying", cv.Version)
	}
}

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

update, err := addon.GetRequiredUpdates(ctx, k8sClient, cmClient, cv)
if err != nil {
	return fmt.Errorf("skipping addon %s: %v", addon.Name, err) // fail-soft per addon
}

When it happens

Trigger: GetRequiredUpdates returns an error while comparing installed vs channel versions — failing to GET the addon's resource or parsing an invalid installed version.

Common situations: Addon resources missing or hand-modified in-cluster, unparsable version annotations from older kOps versions, transient API read errors.
