Xubuntu - обновление возвращает множество ошибок

Я пытаюсь установить OBS Studio на мою Tinker Board S в дистрибутиве ELAR Systems в Xubuntu. Так или иначе, я думаю, что мог коснуться чего-то, чего не должен был иметь, когда пытался скомпилировать, и это как-то испортило мои репозитории. Я разместил этот же вопрос на официальном форуме Tinker Board и на Stack Overflow (он был закрыт, и поэтому я здесь). Я искал и пробовал разные вещи, чтобы заставить это работать целыми днями, и пока у меня ничего нет. Я недостаточно работал с Linux, чтобы точно знать, что происходит, но я думаю, что это может быть либо из-за того, что репозитории сломаны, либо из-за моих ограниченных знаний о Linux что-то сломалось.

Мой вопрос: почему это происходит, как я мог все испортить и как это исправить?

Вот то, что терминал выкладывает на меня всякий раз, когда я звоню sudo apt-get udpateили sudo aptitude update:

Любая помощь очень ценится. В худшем случае я просто установил новую ОС и попробовал еще раз более тщательно.
