Я пытаюсь установить Flash на Lubuntu 16.04 Lenovo s12 2959 и Chromium, похоже, не обнаруживают вспышку.

Вот что произошло, когда я попытался установить flash:

... Я успешно следовал инструкциям по добавлению репозитория ppa: skunk / pepper-flash

sudo add-apt-repository ppa:skunk/pepper-flash

но когда я перезагружаю репозитории, я получаю эти ошибки:

после этого https://launchpad.net/~skunk/+archive/ubuntu/pepper-flash Кажется, что в конце концов не работает для Chromium

Тогда Я зашел в «Настройки» -> «Программы и обновления», проверьте, что там есть репозиторий Canonical Partners, это было ..

Итак, он начал загружать обновления и прочее, пока я не получил ошибку:
