// of the number of enums above. Add any new errors above this line if you

// but is used for other errors that are sent to Omaha. We don't assign any
// particular value for this enum so that it's just one more than the last
// one above and thus always represents the correct count of UMA metrics
// buckets, even when new enums are added above this line in future. See
// metrics::ReportUpdateAttemptMetrics() on how this enum is used.
