I'm trying to install Odoo on a Debian 3.2, but I'm having trouble trying to install its dependencies.

When I try to install python-decorator, I get this error:

The python-decorator package is not available, but some other package references
him. This may mean that the package is missing, has been obsoleted, or is only
is available from another source

E: The package "python-decorator 'has no installation candidate

And this is my sources.list:

deb cdrom:[Debian GNU/Linux 7.8.0 _Wheezy_ - Official amd64 DVD Binary-1 20150110-14:43]/ wheezy contrib main

deb http://security.debian.org/ wheezy/updates main contrib
deb-src http://security.debian.org/ wheezy/updates main contrib

  • Debian 3.2? I assume you mean Debian 7 (Wheezy) with the 3.2 kernel? – Tim Stoop Feb 20 '15 at 09:34
  • yes, Debian 7, I got confused – Javier Marín Feb 20 '15 at 09:51
  • What does the command "apt-cache policy python-decorator" output? Which sources do you have configured? The package is available in Wheezy: https://packages.debian.org/wheezy/python-decorator – Tim Stoop Feb 20 '15 at 09:53
  • python-decorator: Instalados: (ninguno) Candidato: (ninguno) Tabla de versión: It's a clean Wheezy instalation. – Javier Marín Feb 20 '15 at 10:36
  • Can you edit your question and add your /etc/apt/sources.list and the listing in /etc/apt/sources.list.d (if any)? Looks like you do not have external resources configured. – Tim Stoop Feb 20 '15 at 10:45

I fixed it. The problem was with the sources.list, which was looking just in the Debian DVD instead of the official Internet repository.

Using http://debgen.simplylinux.ch/ I generated a new sources.list and after that apt-get update to get it working. This is the sources.list I'm using:

deb http://ftp.es.debian.org/debian stable main contrib non-free

deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free

Make sure you have configured external resources. You can check this by looking at /etc/apt/sources.list and possibly the files in /etc/apt/sources.list.d. A minimal /etc/apt/sources.list that allows you to install packages from the internet archives is:

deb     http://http.debian.org/debian/        wheezy  main
deb     http://security.debian.org/     wheezy/updates  main
deb     http://http.debian.org/debian/        wheezy-updates  main

Then run "sudo apt-get update" and you'll be able to "sudo apt-get install python-decorator".
