error updating addon from %q: %w

Error message

error updating addon from %q: %w

What it means

This is the aggregate error returned at the end of updateAddon: it wraps the accumulated multierr (from manifest read, apply, and/or prune failures) along with the manifest URL, giving one combined failure for the whole addon update in EnsureUpdated.

Solutions

1. Read the wrapped multi-error to see which stage (read/apply/prune) failed
2. Fix the individual addon failure indicated by the wrapped errors
3. Re-run kops apply addons / the channels controller after remediation
