Адаптер Wi-Fi не найден Ubuntu 20.04

Система: Dell Precision T3400 с двойной загрузкой Windows 10 / Ubuntu. В настоящее время система подключена к Интернету через Ethernet. После обновления до Ubuntu 20.04 я получаю сообщение «Адаптер Wi-Fi не найден» при попытке использовать адаптер Wi-Fi EDUP EP-AC1661. Я загрузил драйвер Linux для этого адаптера с http://www.szedup.com/ep-ac1661/ , распаковал архивы и дважды щелкнул по всем файлам install.sh в RTL8821CU_WiFi_linux_v5 .2.5.1_22211_COEX20170310-1212.20170517 папка. Я искал в Synaptic RTL8821CU, но Synaptic вернул: «Не удалось загрузить все индексы репозитория» Я безрезультатно пытался следовать предложениям из статей, полученных в результате поиска источников «Нет Wi-Fi Adaper Found Ubuntu 20.04», скорее всего, из-за моего отсутствия опыта работы с Linux:
