During the initial installation and for each upgrade of a package, <command>dpkg</command> calls the so called <emphasis>maintainer scripts</emphasis> such as the <command>prerm</command> or <command>preinst</command> scripts. These scripts can perform additional actions during the different stages of a package's life-cycle. Script names preceded by <literal>new-</literal> are the scripts from the new version of a package being installed or upgraded to. Script names preceded by <literal>old-</literal> are the scripts from the old version of a package that is being upgraded from.
Durante a instalação inicial e para cada atualização de pacote, o <command>dpkg</command> chama os <emphasis>maintainer scripts (scripts do mantenedor)</emphasis> como o <command>prerm</command> ou <command>preinst</command>. Estes scripts podem realizar ações adicionais durante os diferentes estágios do ciclo de vida de um pacote. Nomes de script iniciados por <literal>new-</literal> são os scripts da nova versão de um pacote sendo instalado ou atualizado. Nomes de script iniciados por <literal>old-</literal> são os scripts de uma versão antiga de um pacote que está sendo atualizado.
During each invocation <command>dpkg</command> will pass certain arguments to each script such as <command>upgrade <replaceable>new-version</replaceable></command>. The invoked script can then either handle the arguments and perform a particular action, or ignore the arguments and return with an exit code of <literal>0</literal>, if nothing needs to be done during that step. In practice many packages will not need to perform an action during every step in the life cycle. Thus a typical configuration script will check for a particular argument and ignore all other ones, implicitly returning with exit code <literal>0</literal>.
Durante cada invocação, o <command>dpkg</command> vai passar certos argumentos para cada script, como por exemplo <command>upgrade <replaceable>new-version</replaceable></command>. O script invocado pode então tanto manipular os argumentos e realizar uma ação particular, ou ignorar os argumentos e retornar com um código de saída de <literal>0</literal>, se nada precisar ser feito durante este passo. Na prática, muitos pacotes não vão precisar realizar nenhuma ação durante cada passo no ciclo de vida. Então um script de configuração típico vai verificar por um argumento em particular e ignorar todos os outros, implicitamente retornando código de saída <literal>0</literal>.
Here is what happens during an installation (or an update). The <replaceable>old-version</replaceable>, <replaceable>new-version</replaceable> and <replaceable>last-version-configured</replaceable> arguments are placeholders for the actual (old and new) version numbers of the package:
Aqui está o que acontece durante uma instalação (ou um update). Os argumentos <replaceable>old-version (versão antiga)</replaceable>, <replaceable>new-version (versão nova)</replaceable> e <replaceable>last-version-configured (última versão configurada)</replaceable> são substitutos para os números de versão reais (o velho e o novo) do pacote:
For an update, <command>dpkg</command> calls the <command>old-prerm</command> script and passes <command>upgrade <replaceable>new-version</replaceable></command> as arguments.
Para uma atualização ("update"), o <command>dpkg</command> chama o script <command>old-prerm</command> e passa <command>upgrade <replaceable>nova-versão</replaceable></command> como argumento.
Still for an update, <command>dpkg</command> then executes the <command>new-preinst</command> script with the arguments <command>upgrade <replaceable>old-version</replaceable></command>; for the initial installation, it executes the <command>new-preinst</command> script and passes <command>install</command> as argument. It may add the old version in the last parameter, if the package has already been installed and removed since (but not purged, and thus configuration files have been retained).
Ainda para uma atualização, o <command>dpkg</command> então executa o script <command>new-preinst </command>com os argumentos <command>upgrade<replaceable>antiga-versão</replaceable></command>; para a instalação inicial, ele executa o script <command>new-preinst </command> e passa <command>install</command> como argumento. Ele pode adicionar a versão antiga no último parâmetro, se o pacote já foi instalado e removido desde então (mas não expurgado ("purged"), e então os arquivos de configuração ficam mantidos).
The new package files are then unpacked. If a file already exists, it is replaced, but a backup copy is temporarily made.
Os arquivos do novo pacote são então desempacotados, se algum arquivo já existe, ele é substituído, mas uma cópia de backup é temporariamente feita.
