переключение основных серверов на альтернативные

[ilyaq]

Здравствуйте. Нужно переключить сервера репозиториев на русские или альтернативные через терминал. Через графику не получается. Какую команду нужно ввести?

[Usermaster]

Поправить sources.list вручную.
Под сполером огигинальный sources.list из Kubuntu 20.04 с настройкой на Российские серверы.
Сравнивайте, правьте.
Лишнего не добавляйте если у Вас этого нету.
Перед правкой сделайте резервную копию оригинального файла на всякий случай.
