 Replying to [comment:3 SergeyBiryukov]:
 > Just noting that `retrieve_password()` was indeed moved from `wp-
 login.php` to `wp-includes/functions.php` in [50129] and further to `wp-
 includes/user.php` in [50140] / #34281.

 > So this seems to be a case of an incomplete upgrade. Downloading the
 [https://wordpress.org/download/ latest version of WordPress] and
 replacing the `wp-login.php` file with a fresh copy should fix the issue.

 @SergeyBiryukov You are right. I was not able to update WordPress through
 admin area due to file permissions inconsistencies. I tried to do it
 manually and did not replace all files.
