O Debian continua pegando os pacotes do sid apesar de nenhum sid em /etc/apt/sources.list

Question

Eu tenho uma máquina com o Debian Lenny instalado. De alguma forma, quando eu faço o apt-get update, recebo esta saída:

sudo apt-get update

Fetched 1870B in 2s (833B/s)                          
Reading package lists... Done

O mais estranho é que meu arquivo /etc/apt/sources.list é assim:

deb http://ftp.de.debian.org/debian lenny main contrib non-free
deb http://ftp.de.debian.org/debian-volatile lenny/volatile main contrib non-free
deb http://ftp.de.debian.org/debian-security lenny/updates main contrib non-free

Como posso livrar-me do espelho lateral?

    

Answer 1

Aparentemente, além do /etc/apt/sources.list, há também o diretório /etc/apt/sources.list.d, que permite que você tenha listas de pacotes adicionais. No meu caso, eu tenho

$ ls -l /etc/apt/sources.list.d
total 4
-rw-r--r-- 1 root root 94 2010-12-16 12:15 sid.list

que aparentemente foi adicionado pelo meu provedor de VDS por algum motivo.

De acordo com o homem,

The /etc/apt/sources.list.d directory provides a way to add sources.list entries in separate files. The format is the same as for the regular sources.list file. File names need to end with .list and may only contain letters (a-z and A-Z), digits (0-9), underscore (_), hyphen (-) and period (.) characters. Otherwise they will be silently ignored.

    

Answer 2

Parece que você está em um ambiente chroot, verifique com algo assim:

[ "$(stat -c %d:%i /)" != "$(stat -c %d:%i /proc/1/root/.)" ] && echo "I'm in a chroot" || echo "main system"

E se sim, simplesmente digite exit para sair.
