Os nomes dos arquivos em /etc/sources.list.d
devem terminar em .list
, se eles forem incluídos como fontes de software.
Como a página man do sources.list diz:
DESCRIÇÃO
The package resource list is used to locate archives of the package
distribution system in use on the system. At this time, this manual
page documents only the packaging system used by the Debian GNU/Linux
system. This control file is /etc/apt/sources.list.
The source list is designed to support any number of active sources and
a variety of source media. The file lists one source per line, with the
most preferred source listed first. The format of each line is: type
uri args The first item, type determines the format for args. uri is a
Universal Resource Identifier (URI), which is a superset of the more
specific and well-known Universal Resource Locator, or URL. The rest of
the line can be marked as a comment by using a #.
SOURCES.LIST.D
The /etc/apt/sources.list.d directory provides a way to add
sources.list entries in separate files. The format is the same as for
the regular sources.list file. File names need to end with .list and
may only contain letters (a-z and A-Z), digits (0-9), underscore (_),
hyphen (-) and period (.) characters. Otherwise APT will print a notice
that it has ignored a file if the file doesn't match a pattern in the
Dir::Ignore-Files-Silently configuration list - in this case it will be
silently ignored.
Tomando um exemplo de esta página , suponha que você queria instalar o chef (do opscode) , o que você faria é:
- Crie e abra um arquivo chamado
opscode.list
:
sudo vim /etc/apt/sources.list.d/opscode.list
- Adicione a linha desejada e salve o arquivo:
deb http://apt.opscode.com/ oneiric main
Os passos acima podem ser combinados para criar um único comando:
sudo echo "deb http://apt.opscode.com/ onereic main" > /etc/apt/sources.list.d/opscode.list
Nota: O comando contém onereic
porque o nome de código do Ubuntu que você está usando é Onereic . Se você estivesse usando Precise (12.04), você teria writter precise
.
