Ignorando dependências excessivas ao instalar o r-base-core

Question

Estou tentando instalar o R (via r-base-core) em um servidor do Ubuntu 10.10.

Está a tentar instalar todos os seguintes itens:

Need to get 94.5MB of archives.
After this operation, 284MB of additional disk space will be used.

Minha infra-estrutura tem espaço limitado e eu prefiro não perder tanto instalando programas / bibliotecas que nunca podem ser usados em um servidor (libgnome? firefox ??)

1. Por que temos todas essas dependências? Existe uma maneira de ver facilmente toda a árvore de dependências ou motivações por trás de cada uma?
2. Eu realmente não me importo com dependências de janelas (já que elas não podem ser usadas). Existe alguma boa maneira de forçar o apt / dpkg a ignorá-los --- ou é aconselhável apenas compilar a partir da fonte?

Answer 1

(2) Experimente

sudo apt-get --no-install-recommends install r-base-core

O Ubuntu por padrão instala não apenas o Depende , mas também os pacotes Recomendados .

(1) Se você estiver interessado na árvore de resolução de pacotes, faça algo como

apt-get --dry-run -o Debug::pkgDepCache::AutoInstall=yes install r-base-core

Exemplo de saída

$ apt-get --dry-run -o Debug::pkgDepCache::AutoInstall=yes install r-base-core
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!
