I cannot update some of the modules and the Drupal core itself from "Available Updates" menu. The error is "No available releases found". However, I can list the updates with

While checking updates Drupal creates some rows inside the
key_value table which should be deleted after checking is complete but looks like they doesn't for some reason. So deleting the related rows manually solved my problem:
DELETE FROM key_value WHERE collection = 'update_fetch_task';
If it is not possible to execute SQL queries via MySQL CLI on your server, then you might want to create a
hook_update_N() in a custom module:
$database = \Drupal::database(); $database ->delete('key_value') ->condition('collection', 'update_fetch_task') ->execute();
I couldn't find the key_value table anywhere.
After a lot of research, I stumbled upon this article by Marius Cârneală. https://www.mariusc.name/content/no-available-releases-found-drupal-error-fix
His SQL command worked for me: truncate cache_update
You can also run it using drush: drush sqlq truncate cache_update
According to this post https://www.drupal.org/project/drupal/issues/3120168, if you click on "Check manually", it fixes the problem. I tried it and it worked.
Edit: I used this method on Drupal ^8.8
