[РЕШЕНО] Pacman ключи и, возможно, не только...

Попробуйте кеш пакетов почистить и папку сборки пакетов егурта
yauort -Scc
Да да да
И почистить директорию сборки

И еще у вас локальной репы ни какой нет? @red правильно заметил про то что пакет обновился пол года назад а у вас только сейчас обновление вылезло
Локальной точно - нет...

Как я понял, дело уже не в ёгурте...
Пробовал и тризеном и пикауром - та же ошибка...
Получается так:

    Хелпер собирает пакет, пытается его поставить и бьёт ошибку.
    Я копирую пакет в любое другое место.
    Пытаюсь поставить его пакманом.
    Получаю ту же ошибку.
OSKiller
Хелпер собирает пакет
зачем вообще его собирать ? он лежит уже собранный в офф.репозитории
или это какая-то специфическая сборка ?
обычно для установки должно хватить простых действий
sudo pacman -S jansson

что у вас за репозиторый подключен ?
покажите свой
cat /etc/pacman.d/mirrorlist
да и за одно
cat /etc/pacman.conf
/etc/pacman.d/mirrorlist

на первый взгляд всё нормально
хотя есть непонятность с mirrorlist который был сгенерирован
## Generated on 2019-04-02
то есть в тот же день(2 апреля) когда был задан вопрос, и не понятно что стояло до этого
но не суть

для начала подберите себе нормальный репозиторий для обновлений, обычно берут территориально поближе с маленьким пингом и толстым каналом.
Для определённой страны можно сгенерировать здесь, есть еще специальные утилиты для отбора подходящих зеркал но это вы и сами можете поискать на форуме или wiki.
Заменив /etc/pacman.d/mirrorlist раскомментируйте только одно зеркало после чего выполните обновление базы и установку пикетов с возможным откатом версий(такое желательно делать всегда когда происходит смена зеркала репозитория)
/система использует только самый первый рабочий репозиторий который раскомемнтирован/
sudo pacman -Syyuu

затем попробуйте еще раз установить этот пакет
sudo pacman -S jansson
К рекомендациям red можно добавить еще на всякий пожарный опцию --debug , типа pacman --debug -S ... , может поможет получить место затыка.

Исправьте на

Для локальных файлов базы нет если только сами не создавали
Почистите кеш и директорию сборки.
И попробуйте снова
