Пакету нужен мантейнер.

(Ответ для Антон Мидюков на комментарий #2)
> Пакету нужен мантейнер.

Мантейнер не нашёлся, поэтому пакет был удалён из Сизифа:
https://packages.altlinux.org/en/tasks/331679/

радикально. а ведь эта штука очень востребована в учебном процессе.

Очень надеюсь, что после удаления мантейнер найдётся. Можете багу повесить на сборку пакета с ссылкой на этот баг.
