Enak Pakai Repository di HDD

Sesuai judul, kenapa saya bisa bilang enak?
Lebih baik teman mencobanya, tentu dengan repository lokal yang ada di HDD kita sendiri proses installasinya pun terasa sangat cepat tanpa harus mend-download terlebih dahulu.
Lantas bagaimana saya bisa melakukan hal itu, sedangkan ukuran repository sangat besar sekali?? Itu sangat mudah, di dalam sebuah komunitas tentunya para anggota akan sangat senang hati untuk saling berbagi, salah satunya dalah berbagi repository. Kita hanya perlu meng-copy nya dan melakukan sinkronisasi ke repo server lokal, kambing UI misalnya untuk mendapatkan pembaharuan repository.
Karena kita hanya spesifik untuk melakukan sinkronisasi, maka saya menggunakan debmirror untuk prakteknya. Nah bagaimana tutorialnya, bisa lihat dibawah ini

Asumsi

folder repo : /media/Data/Repository/ubuntu
server      : kambing.ui.ac.id
GNUPGHOME   : /media/Data/Repository/mirrorkeyring

Membuat Mirrorkeyring untuk debmirror

Buat folder untuk mirror keyring

mkdir /media/Data/Repository
mkdir /media/Data/Repository/mirrorkeyring
gpg --no-default-keyring --keyring /media/Data/Repository/mirrorkeyring/trustedkeys.gpg --import /usr/share/keyrings/ubuntu-archive-keyring.gpg

Sebelum bisa digunakan dengan baik, kadang kala kita perlu beberapa kali menjalankan perintah

gpg --no-default-keyring --keyring /media/Data/Repository/mirrorkeyring/trustedkeys.gpg --import /usr/share/keyrings/ubuntu-archive-keyring.gpg

Mengkonfigurasi debmirror

• Install debmirror & buat folder tempat repo

sudo apt-get install debmirror
mkdir /media/Data/Repository
mkdir /media/Data/Repository/ubuntu

• Buatlah script mirror

sudo touch /usr/local/bin/mirrorbuild.12.04.sh
sudo chmod -Rf 777 /usr/local/bin/mirrorbuild*
sudo chown -Rf nobody.nogroup /usr/local/bin/mirrorbuild*
sudo nano /usr/local/bin/mirrorbuild.12.04.sh

• Masukan script berikut

#### End script to automate building of Ubuntu mirror ####                                                                                    

Simpan script jika sudah selesai di edit semua-nya.

• Ubah ijin agar file mirrorbuild.sh & folder repo

sudo chmod -Rf 777 /usr/local/bin/mirrorbuild.12.04.sh 
sudo chown -Rf root.root /media/Data/Repository/ubuntu
sudo chmod -Rf 571 /media/Data/Repository/ubuntu

• Jalankan mirrorbuild.sh

sudo mirrorbuild.12.04.sh

Kondisi diatas adalah untuk repository Ubuntu 12.04 64bit, karena pada komputer saya menggunakan sistem operasi Ubuntu 12.04 64bit. Dan folder Repository ada pada partisi yang berbeda dengan root, partisi tersebut saya mount pada direktori /media/Data
