Error message

you might have not staged your files correctly, please execute 'kops get assets --copy'

What it means

findHash failed to determine the file's SHA256 hash by any means (well-known hashes, .sha256 sidecar file, or download), while an explicit FileRepository (asset staging location) is configured. Because assets are supposed to be pre-staged there, a missing hash usually means the staging copy is incomplete, so kops points the user at 'kops get assets --copy'.

Solutions

1. Run 'kops get assets --copy' to stage all required file assets into the file repository, then retry.
2. Verify assetsLocation.FileRepository points at the repository actually populated with the staged files.
3. Check the target file exists in the repository with its .sha256 hash file.
4. If not using a mirror, unset FileRepository so kops reports the generic 'cannot determine hash' error instead.

Example fix

// before
kops create cluster ... --set fileRepository=https://files.example.com/kops # repo empty
// after
kops get assets --copy --asset-file-repository https://files.example.com/kops
kops create cluster ... --set fileRepository=https://files.example.com/kops

// before building, confirm the staged repo serves the file and its hash
for _, f := range requiredFiles {
	h, err := fetchHashFor(fileRepository + "/" + f)
	if err != nil { return fmt.Errorf("file %s not staged in %s: run 'kops get assets --copy'", f, fileRepository) }
	_ = h
}

fileAsset, err := assetBuilder.RemapFile(u, knownHash)
if err != nil {
	if strings.Contains(err.Error(), "kops get assets --copy") {
		return fmt.Errorf("staged file assets incomplete: run 'kops get assets --copy' with fileRepository %s", fileRepository)
	}
	return err
}

When it happens

Trigger: Using --set fileRepository (assetsLocation.FileRepository) and calling RemapFile for a file whose hash cannot be resolved from the staged repository or downloaded sources.

Common situations: Ran 'kops get assets' without --copy (or the copy was interrupted); the file is new/kind-specific and missing from the file repository; wrong FileRepository configured; offline environment where the download fallback fails.
