SyncEvolution: “Сравнение было невозможно” и никакая синхронизация CardDav больше

У меня есть телефон Ubuntu, и он использует syncevolution в качестве бэкенда для контактов. Я использую командные строки, чтобы иметь мои контакты CardDav по моему телефону. Но так как я переключился от сам подписанный сертификат letsencrypt (связанный или не), у меня есть тонны ошибок.

First ERROR encountered: local, status 20048

Doing a slow synchronization may lead to duplicated items or
lost data when the server merges items incorrectly. Choosing
a different synchronization mode may be the better alternative.
Restart synchronization of affected source(s) with one of the
following sync modes to recover from this problem:
    slow, refresh-from-server, refresh-from-client

Analyzing the current state:
    syncevolution --status target-config@owncloud contacts

Running with one of the three modes:
    syncevolution --sync [slow|refresh-from-remote|refresh-from-local] target-config@owncloud contacts

Таким образом, я решил попробовать некоторые вещи, которые я не помню точно (как принуждение синхронизации с обновлением от локального/удаленного) и изменил конец предыдущего журнала:

Затем:

Data modified @default during synchronization:

Comparison was impossible.

Начиная с этого шага я не могу больше удалить контакт из своего телефона и заставить его синхронизировать на сервере (для удаления контакта на самом сервере), вместо этого контакт просто "очищен" (любая информация исчезают, но контакт все еще здесь, и сохраните firstname и lastname). Я могу синхронизировать контакт, созданный на сервере по моему телефону, и отправить контакты, созданные по моему телефону на сервере.

Кажется, что резервная база данных повреждается, но я не могу сбросить полностью свою конфигурацию. Я просто хотел запуститься нулем, но я не могу найти способ сделать это.:'(
