Debian Mirror Redirector

Veremos aqui como alterar os repositórios do arquivo /etc/apt/sources.list de forma a obter os benefícios do Debian Mirror Redirector no Debian Squeeze.

As principais vantagens ao utilizá-lo é que os pacotes serão baixados dos espelhos mais rápidos (inclusive dos novos), de acordo com sua geo-localização e a ausência de mirrors off-line, desatualizados etc.

Como exemplo, visitem o link abaixo e vejam o que ocorre:

sources.list

A alteração a ser realizada é a troca do início de cada mirror Debian (Standard, Security, Volatile e Backports) por: deb http://http.debian.net/debian/

Vejam, como exemplo, parte do meu sources.list anterior:

### Debian 6.0.5 Squeeze/Stable.
### Chave GPG: sudo apt-get install debian-archive-keyring debian-keyring
deb http://sft.if.usp.br/debian/ squeeze main contrib non-free
deb http://ftp.debian.org/debian/ squeeze main contrib non-free

### Debian 6.0.5 Squeeze/Stable Security 'Updates'.
deb http://sft.if.usp.br/debian-security/ squeeze/updates main contrib non-free
deb http://security.debian.org/ squeeze/updates main contrib non-free

### Debian 6.0.5 Squeeze/Stable 'Updates' Volatile.
deb http://sft.if.usp.br/debian/ squeeze-updates main contrib non-free
deb http://ftp.debian.org/debian/ squeeze-updates main contrib non-free

### Debian 6.0.5 Squeeze/Stable 'Backports'.
### Chave GPG: gpg --keyserver hkp://subkeys.pgp.net --recv-keys 16BA136C && gpg --export 16BA136C | sudo apt-key add -
deb ftp://sft.if.usp.br/debian-backports/ squeeze-backports main contrib non-free
deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free

### Debian Backports Mozilla Team.
### Chave GPG: wget -O- -q http://mozilla.debian.net/archive.asc | gpg --import; gpg --export -a 06C4AE2A | sudo apt-key add -
deb http://mozilla.debian.net/ squeeze-backports iceweasel-release

### Debian 6.0.5 Squeeze/Stable 'Multimedia'.
### Chave GPG: sudo apt-get install deb-multimedia-keyring debian-multimedia-keyring
deb http://sft.if.usp.br/debian-multimedia/ squeeze main non-free
deb http://www.deb-multimedia.org squeeze main non-free
deb http://www.deb-multimedia.org squeeze-backports main

E abaixo, vejam como o mesmo ficou depois das alterações (ou seja, bem mais simplificado e com menos repositórios):

### Debian 6.0.5 Squeeze/Stable.
### Chave GPG: sudo apt-get install debian-archive-keyring debian-keyring
deb http://http.debian.net/debian/ squeeze main contrib non-free

### Debian 6.0.5 Squeeze/Stable Security 'Updates'.
deb http://http.debian.net/debian-security/ squeeze/updates main contrib non-free

### Debian 6.0.5 Squeeze/Stable 'Updates' Volatile.
deb http://http.debian.net/debian/ squeeze-updates main contrib non-free

### Debian 6.0.5 Squeeze/Stable 'Backports'.
### Chave GPG: gpg --keyserver hkp://subkeys.pgp.net --recv-keys 16BA136C && gpg --export 16BA136C | sudo apt-key add -
deb http://http.debian.net/debian-backports/ squeeze-backports main contrib non-free

### Debian Backports Mozilla Team.
### Chave GPG: wget -O- -q http://mozilla.debian.net/archive.asc | gpg --import; gpg --export -a 06C4AE2A | sudo apt-key add -
