Por que recebo o erro 404 em .canonical.com em alguns servidores de arquivamento?

Question

Eu tenho tido um problema de pacote quebrado por um bom tempo agora, e isso estava me causando problemas mais cedo quando eu estava tentando instalar rvm. Após algumas pesquisas, abri o gerenciador de fontes de software "gksu software-properties-gtk" e desmarcou os repositórios archive.canonical.com de "Other Software" e não tenho mais nenhum pacote corrompido. Esses repositórios são importantes? Eu deveria estar preocupado com a saúde das minhas instalações? Eu sou um noob do Ubuntu, então isso está me preocupando.

É importante, aqui estão os erros "sudo apt-get update":

a linha que contém [distro] deve ser substituída por precise se você estiver executando o 12.04.

1. Para editar a lista de fontes, abra um terminal.
2. edite /etc/apt/sources.list com gksu gedit /etc/apt/sources.list e uma janela do gedit do arquivo será aberta.
3. encontre as linhas que dizem deb http://archive.canonical.com [distro]/partner e deb-src http://archive.canonical.com [distro]/partner
4. deb http://archive.canonical.com precise/partner e deb-src http://archive.canonical.com precise/partner

Deve haver seis linhas para editar de acordo com o seu erro.

Answer 2

No xubuntu 12.04, o flashplugin-installer falha. O arquivo ubuntu é acessado, o arquivo que ele está procurando (o arquivo .orig.tgz flashplugin-installer tgz) existe, mas o download pára.

Meu método para consertar isso foi usar synaptic como root e remover completamente o flashplugin-installer do sistema apt.

Então eu fui aqui:
link

e baixou o arquivo da Adobe oferecido, e fez uma instalação manual:

• descompacte o arquivo
• leia o arquivo Leiame e siga as instruções
• Feito.

O Readme é facilmente seguido, mas requer que seja executado como root usando su - ou usando sudo .
Esta correção é para o instalador de 32 bits do xubuntu 12.04 update 4.
