проблема обновления 19.04 & ldquo; Не удалось загрузить некоторые индексные файлы. Они были проигнорированы, или вместо них использовались старые. & Rdquo;

Посмотрел в Интернете решение, ответы отсутствуют.

Distributor ID: Ubuntu
Description:    Ubuntu 19.04
Release:    19.04
Codename:   disco

Я попробовал следующие решения и сумел выяснить, что у меня есть устаревший список источников (я думаю). Как мне обновить список источников в 19.04, потому что все решения, которые мне удалось найти, потерпели неудачу.

Проблема возникла, когда я не смог выполнить обновление с помощью следующей команды в ходе исследования. Я считаю, что это устаревший список источников

sudo apt update

. Это вернуло следующий результат
