Все install Команды терпят неудачу из-за этого я верю

Я просто хотел бы вернуть все в нормальное состояние, поскольку я испортил это при удалении virtualbox,kubectl. Я просто знакомился с этим. Эксперимент обратно выстрелил.

Я пытался заменить sources.list используя это, между прочим, я пытался.

Любая помощь приветствуется.

Добавьте открытый ключ к вашей связке ключей с помощью команды, подобной этой:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

Тогда вы должны бежать sudo apt-get update обычно.
