Yeni Ubuntu 12.04 kurulum güncellemesinden sonra neden yüklenmiyor?

Bir bilgisayara Ubuntu 12.04 yükledim. Güncelleme olmadan her şey yolunda. Kurulumdan hemen sonra, indirmek için yaklaşık 200 MB güncellemeleri gösteriliyordu. O zamandan beri tüm güncellemeleri yüklemeye çalışıyorum. Şimdi kısmen tamamlandı, bazı yazılımlar (firefox, VLC) güncellendi. Hala indirmek için 39.3 MB güncellemeleri gösteriyor ve tekrar tekrar başarısız oluyor. Bu 39.3 MB güncellemeleri her yüklemeye çalıştığımda, internete bağlanamadığını gösteriyor, ancak bağlantımla ilgili bir sorun yok (Ağ göstergesi bağlı olduğunu gösteriyor ve herhangi bir şeye göz atabilir ve indirebilirim). Bana şu mesajı veriyor:

Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch

Bunun kaynaklar listesiyle ilgili bir sorun olduğunu düşündüm. Bu yüzden aşağıdaki komutu verdim

sudo rm -vf /var/lib/apt/lists/partial/*

Daha önce, farklı bir bilgisayarda benzer türde bir sorunla karşılaştım. O zaman, bu çözüm benim için çalıştı, ama şimdi hala bu sorunla karşı karşıyayım. Herkes lütfen bu sorunu çözmeme yardım et.

Güncelleme

İşte çıktı sudo apt-get update

# aptitude update
