E: Тип «Лицензия» неизвестен в строке 1 в списке источников /etc/apt/sources.list.d/yarn.list E: Список источников не может быть прочитан [дубликат]

Когда я запускаю

sudo apt-get update

, я получаю такую ​​ошибку:

E: Type 'License' is not known on line 1 in source list /etc/apt/sources.list.d/yarn.list
E: The list of sources could not be read.

Я попытался ввести это местоположение и удалить строку 1. Затем я повторно запустил команду.

Результат

Та же ошибка отображается для следующей строки и остается такой же! Нужно ли мне удалять все строки? Что мне делать?

Редактировать

Также, когда я запускаю эту команду,

cat /etc/apt/sources.list.d/yarn.list

выводит
