Linux users ලට software install කරන්න ඔනි repo host කරල තියෙන්නෙ මෙන්න මෙ වගෙ mirrors ව්ල.
Mirro server වලින් අපිට තියෙන වාසිය තම්යි එවා අපිට ලන් වෙන්තර්ම්ට අපිට එවා ව්ලින් files download කරන්න පුලුව්ම් වෙගෙ වෑඩිවෙන්ව.ඉතින් අපිට ලග mirrors ගොඩක තිබුනහම අපිට වෑඩිම වෙගයෙන download කරලන්න පුලුව්ම server එක හොයගන්න තියෙන හොඩම විඩිය තම ping කරල බලන එක.
