Biar inget mending disimpan di blog sendiri, cara update source list repository ubuntu. Yang akan saya update adalah repo ubuntu 8.10 karena versi ubuntu ini yang cocok sama PC saya. Udah coba karmic ng cocok, pas tanya ke professor linux emang banyak kutunya karmic.

Untuk mengubah daftar repositori, ada 2 cara, yaitu melalui Terminal dan “Synaptic Package Manager” :

Melalui terminal:

1. Masukkan perintah berikut:

sudo gedit /etc/apt/sources.list

2. Hapus seluruh baris dan ganti dengan baris-baris pada salah satu server dari daftar di atas. Contoh:
deb http://dl2.foss-id.web.id/ubuntu intrepid main restricted universe multiverse
deb http://dl2.foss-id.web.id/ubuntu intrepid-updates main restricted universe multiverse
deb http://dl2.foss-id.web.id/ubuntu intrepid-security main restricted universe multiverse
deb http://dl2.foss-id.web.id/ubuntu intrepid-backports main restricted universe multiverse
deb http://dl2.foss-id.web.id/ubuntu intrepid-proposed main restricted universe multiverse
3. Ketikkan perintah

sudo apt-get update
sudo apt-get upgrade

Melalui Synaptic Package Manager:

1. Buka menu: System | Administration | Synaptic Package Manager
2. Pilih menu: Settings | Repositories
3. Pilih tab “Third-Party Software”
4. Pilih “Add”
5. Masukkan baris pertama pada salah satu server repositori pada daftar di atas. Misalnya:

deb http://kambing.ui.edu/ubuntu intrepid main restricted universe multiverse

6. Klik “Add” lagi, lalu isikan baris berikutnya. Lakukan langkah ini hingga semua baris pada server tersebut selesai anda masukkan.
7. Setelah selesai, centang setiap item pada daftar “Third-Party Software”
8. Klik “Close”
9. Klik “Reload” pada ikon di sebelah kiri atas

Silahkan gunakan source list yang terdekat dari server anda
