Linux за българи: Форуми

Ами ето какво се "случи".Имам си инсталиран дебиан на една слаба машина,която не се ползва често.След може би 1 седмица пуснах отново машината и реших да направя apt-get update & apt-cache search *
Само че започна да дава грешки.По-долу ще постна грешките,sources.list,а от вас се надявам да ми помогнете да реша проблема,защото не смятам,че реинстал на системата е правилният начин (winblows way).
Пробал съм с различни apt sources,но няма разлика.Ако може препоръчайте някои лист,който според вас е най-удобен.
