Comment (by ocean90):

 In [changeset:"38206"]:
 {{{
 #!CommitTicketReference repository="" revision="38206"
 Update/Install: Replace "error" and "-1" failure messages with a more
 meaningful one.

 * "-1" is an invalid nonce error, show 'An error has occurred. Please
 reload the page and try again.'.
 * "error" means that the connection to the server was lost, show
 'Connection lost or the server is busy. Please try again later.'.
 * Escape the message in `wp-updates-admin-notice` because the response may
 include HTML.
 * Remove HTML tags in `wp.updates.isValidResponse()` to make PHP's error
 messages more readable.

 Merge of [38205] to the 4.6 branch.

 Props azaozz for review.
 See #37583.
