Bu sorunu nasıl çözer ve bu hatayı almazsınız? Lütfen

Her zaman Ubuntu 12.04 paketlerini güncellediğimde yapmaya çalıştığım bir şey, onları en yakın / en iyi ayna / sunucudan indireceğimden emin olmaktır.

1. Yazılım merkezini başlatarak başlayın.

2. Menü çubuğundan düzenle'yi ve ardından Yazılım Kaynakları'nı seçin. ..

3. İndirme Kaynağı seçenekleri için açılır oku tıklayın.

4. Başka birini seçin.

5. "En İyi Sunucuyu Seç" i tıklayın.

6. Yazılım merkezi artık konumunuz için en iyi aynayı bulmak için bir dizi test gerçekleştirecek.

Https://launchpad.net/ubuntu/+mirror/mirrors.ispros.com.bd-archive adresine bakıldığında , Bangladeş aynasının henüz Hassas paketlerle güncellenmediği anlaşılıyor. Yakınlarda farklı bir ayna seçmek (Hindistan aklıma geliyor) veya bu konuda bir hata bildirmek isteyebilirsiniz .

Aldığınız hata, bağlantının gerçekten kaldırılmış olmasıdır. Bu geçici olabilir veya sunucu düzgün çalışmıyor veya bakım altında olmayabilir. (Paket dosyalarınız sunucuya yüklenmemişse)
Bunu çözmek için indirme kaynağınızı değiştirmeyi deneyin (bu, sunucu)
