omitir arquivos de ícones do download de atualizações das listas de pacotes Debian 9.5 amd64?

Question

situação

quando eu estou atualizando as listas de pacotes do Debian 9.5 amd64 (stable, backports, test, unstable) usando APT ou APTITUDE, o tamanho do download da atualização é, a partir desta postagem, cca 60 MB com metade do tamanho sendo ícone arquivos, por exemplo ícones-128x128.

Acredito que não preciso fazer o download de ícones, pois não estou usando gerenciadores de pacotes da GUI.

meta

Eu gostaria de limitar o tamanho do download das atualizações ao mínimo para economizar tempo.

qustions

é possível atualizar as listas de pacotes sem baixar os arquivos de ícones? o que mais é possível omitir do download da atualização? se sim, como? se não, por quê?

    

Answer 1

O que você está vendo provavelmente é causado pela atividade de appstream .

Consulte o link ou link .

Com appstream instalado, sudo apt update produziria algo assim (no Xubuntu 18.10):

Reading package lists... Done

Os downloads para ícones no exemplo acima são relativamente pequenos, mas podem ter vários MB em distros que estão em estágio alfa ou beta de desenvolvimento.

Se, como você diz,

I do not need to download icons as I am not using GUI package managers.

simplesmente execute sudo apt purge appstream e examine a saída antes de prosseguir:

$ sudo apt purge appstream*
