apt-get update не работает + ubuntu 32-разрядный Vs 64-разрядный

Я новичок в платформе linux. Пожалуйста, не ставьте этот вопрос как дубликат, прежде чем читать его полностью.!

Моя система работает на процессоре intel i5, а недавно установленная ОС [ f4]. Мне нужно было установить набор библиотек для моего инструмента разработчика Android (ADT) для правильной работы.

Это одна из ссылок, которые я подал в суд для этой цели.

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs 

Я также использовал ссылки ! d3]

Но когда я делаю sudo apt-get update, он неоднократно отображает следующие предупреждающие сообщения.

E: Some index files failed to download. They have been ignored, or old ones used instead.

Я попытался решить проблемы, используя различные ответы внутри этот форум, который просит отредактировать файл sources.list. Но у меня нет этого содержимого (binary-i686 or binary-i586) в файле sources.list.

Может кто-нибудь помочь мне решить эту проблему !? Пожалуйста, не забудьте ответить командами, поскольку я очень мало знаю о linux terminal commands !!
