2.2.5 Repositório backports

Se um dos objetivos do Debian é a estabilidade, o seu preço é a utilização de software bastante testado e, portanto, antigo. No entanto, pode surgir necessidade de instalar software mais recente o inexistente à data de saída do debian Wheezy. Para isso existe o repositório backports, que disponibiliza versões mais recentes ou inexistente à data de lançamento do Wheezy.

A localização do repositório deve ser adicionada à lista existente em /etc/apt/sources.list:

/etc/apt/sources.list

# [...]

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

# [...]

Uma simples atualização dos repositórios deverá listar o repositório wheezy-backports:
