Adicione e remova canais de atualização de maneira fácil

15

Eu sei que existe uma GUI no Ubuntu Software & Updatespara ativar os canais de atualização

  • atualizações
  • proposto
  • backports
  • segurança

como mostrado nesta captura de tela:

insira a descrição da imagem aqui

Estou procurando uma maneira fácil de fazer isso de dentro de um terminal usando comandos como

sudo apt-add-update enable updates
sudo apt-add-update enable proposed
sudo apt-add-update enable backports
sudo apt-add-update enable security

sudo apt-add-update disable updates
sudo apt-add-update disable proposed
sudo apt-add-update disable backports
sudo apt-add-update disable security

e uma coisa adicional

sudo apt-add-update enable default

sudo apt-add-update disable default

Alguns exemplos para uma melhor compreensão

  1. Um vazio sources.list

    • cat /etc/apt/sources.list

      <empty>
    • sudo apt-add-update enable security

      <empty>
  2. Um repositório ativado ( main)

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily main
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily main
      deb http://archive.ubuntu.com/ubuntu wily-security main
  3. Dois ou mais repositórios ativados em uma ou duas linhas

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily main universe

      ou

      deb http://archive.ubuntu.com/ubuntu wily main
      deb http://archive.ubuntu.com/ubuntu wily universe
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily main universe
      deb http://archive.ubuntu.com/ubuntu wily-security main universe

      ou

      deb http://archive.ubuntu.com/ubuntu wily main
      deb http://archive.ubuntu.com/ubuntu wily-security main
      deb http://archive.ubuntu.com/ubuntu wily universe
      deb http://archive.ubuntu.com/ubuntu wily-security universe
  4. Com deb-srcentradas

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily main universe
      deb-src http://archive.ubuntu.com/ubuntu wily main universe
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily main universe
      deb-src http://archive.ubuntu.com/ubuntu wily main universe
      deb http://archive.ubuntu.com/ubuntu wily-security main universe
      deb-src http://archive.ubuntu.com/ubuntu wily-security main universe
  5. Com deb-srcentradas inativas

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily main universe
      # deb-src http://archive.ubuntu.com/ubuntu wily main universe
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily main universe
      # deb-src http://archive.ubuntu.com/ubuntu wily main universe
      deb http://archive.ubuntu.com/ubuntu wily-security main universe
  6. A defaultcoisa

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily-security universe
    • sudo apt-add-update enable default

      deb http://archive.ubuntu.com/ubuntu wily universe
      deb http://archive.ubuntu.com/ubuntu wily-security universe
  7. Apenas uma entrada e a disableação

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily-security universe
    • sudo apt-add-update disable security

      <empty>
  8. Servidores diferentes ou iguais para diferentes ou os mesmos repositórios, respeite cada servidor

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily universe
      deb http://us.archive.ubuntu.com/ubuntu wily main
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily universe
      deb http://us.archive.ubuntu.com/ubuntu wily main
      deb http://archive.ubuntu.com/ubuntu wily-security universe
      deb http://us.archive.ubuntu.com/ubuntu wily-security main
  9. Diferentes versões do Ubuntu para diferentes repositórios, respeite cada versão

    • cat /etc/apt/sources.list

      deb http://archive.ubuntu.com/ubuntu wily main universe
      deb http://archive.ubuntu.com/ubuntu trusty main
    • sudo apt-add-update enable security

      deb http://archive.ubuntu.com/ubuntu wily main universe
      deb http://archive.ubuntu.com/ubuntu trusty main
      deb http://archive.ubuntu.com/ubuntu wily-security main universe
      deb http://archive.ubuntu.com/ubuntu trusty-security main
  10. PPAs ou outras fontes de pacotes (não Canonical) na sources.list?

    Ignorar!

  11. Não altere os protocolos, por exemplo https, http, tor, ...

27 de novembro de 2015 Atualização :

A segunda versão do script ainda me deixou insatisfeita com o inchaço do código fonte e com o fato de eu ter que empregar várias ferramentas diferentes. Por isso, tentei reescrever o script apenas no AWK.

O novo script usa AWK puro e adere muito melhor aos requisitos. Essencialmente, ele reescreve /etc/apt/sources.listtoda vez que é executado.

Após a execução do script, a atualização é necessária, portanto, execute sudo apt-get updateapós a saída do script com êxito.

O arquivo deve ter permissões executáveis ​​ativadas com chmod +x add-update.awke ser salvo em qualquer um dos diretórios contidos na $PATHvariável. Particularmente, é recomendável salvar o script na $HOME/binpasta (que também deve ser anexada à $PATHvariável).

Um backup do /etc/apt/sources.listarquivo original não é necessário, mas é altamente recomendável. Para fazer backup do arquivo, faça

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

Uso:

sudo ./add-update.awk -v ACTION=[enable|disable|help] -v SOURCE=[updates|backports|security|proposed]

Demo:

sergrep:$ cat /etc/apt/sources.list

Analisei a fonte do Ubuntu Software Center que foi escrita em python.

Depois, escrevi o seguinte código funciona bem. aptsourcesé um módulo python usado pelo Ubuntu Software Center para gerenciar /etc/apt/sources.liste /etc/apt/sources.list.d.

            sourcelist.list.append(sourceentry)

Salve este código com o nome do arquivo /usr/local/bin/apt-add-update. E, em seguida, execute da seguinte maneira.

Uso:

## testing

apt-add-update  enable|disable  default|security|updates|proposed|backports  [file]


## real

sudo  apt-add-update  enable|disable  default|security|updates|proposed|backports

Aqui principais pontos:

Analisei o arquivo porque estava procurando outras opções.

  • Verifica se algum é um espelho, inclusive oficial (releases antigos, portas) ou outros espelhos fornecidos pela comunidade carregados do python-aptpacote (ele contém um arquivo com todos os espelhos).

    /usr/share/python-apt/templates/Ubuntu.mirrors
  • Sempre mantenha o URI oficial no arquivo. Portanto, mesmo com todos desativados, ele manterá uma linha comentada para uma configuração de persistência. Resolve as linhas ao mínimo com o tipo de classificação alfabética, url, dist, comp.

  • Imprime no stdout se ele receber um arquivo de entrada como terceiro argumento ou se não houver permissão para gravar /etc/apt/sources.list

  • Não suporta [ options ]como [ arch=amd64 ].
  • Caiu o disable defaultque obrigo o usuário a especificar o que desativar.
  • Não gosto da última opção (9), porque estou misturando repositórios de propósito. Portanto, eles devem ser tratados como repositórios de terceiros.

Eu acho que se o ifile não existir, basta inserir um código de erro e sair.

Você pode fazer isso de uma maneira muito simples usando add-apt-repository.

Por exemplo, você pode adicionar proposedpor

sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ $(lsb_release -sc)-proposed restricted universe multiverse main"

Ele irá adicionar debe deb-srclinhas para /etc/apt/sources.list. Mas a linha de origem será comentada.

Se você executar add-apt-repositorycom o -sparâmetro, ele não comentará deb-src.

Você pode ativar securitypor

sudo add-apt-repository "http://security.ubuntu.com/ubuntu/ $(lsb_release -sc)-security restricted universe multiverse main"

Sim, eu poderia fazer isso dessa maneira. Mas eu precisaria dos repositórios e de um servidor e não simplesmente de um add securityou add proposed.

@ AB Não está claro o que você deseja. Você precisa de um comando mais simples ou o quê? Este comando faz exatamente o que você faz na GUI.

Conforme descrito na pergunta: "Estou procurando uma maneira fácil de fazer isso de dentro de um terminal usando comandos como ... Talvez algo como: sudo apt-add-update security"
AB
E o que há de errado com este comando? Que é longo? Você pode atualizar por sudo apt-get update. E é muito fácil diminuir o comando.

Sim, sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ wily-proposed restricted universe multiverse main"é muito longo para apoiar outras pessoas. Eu tive que recuperar repositórios existentes anteriormente e o servidor usado.
