 It is another instance of this one:
 https://core.trac.wordpress.org/ticket/34164

 If the environment is set up to report all errors, line 1075 of `wp-
 includes/l10n.php` creates an `E_NOTICE` with `Undefined index: host`
 message.

 Reason:
 At the time of installation the `$site_url` array does not yet have a
 `'host'` key, so `$site_url['host']` is undefined.

 You can see here:
 https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/l10n.php#L1075
 `} elseif ( ! isset( $src_url['host'] ) || $src_url['host'] ===
 $site_url['host'] ) {`

 A proper condition would look like:
 `} elseif ( ! isset( $src_url['host'] ) || ( isset($site_url['host']) &&
 $src_url['host'] === $site_url['host'] ) ) {`
