de man apt-get

   Simulated runs print out a series of lines, each representing a
   dpkg operation: configure (Conf), remove (Remv) or unpack (Inst).
   Square brackets indicate broken packages, and empty square brackets
   indicate breaks that are of no consequence (rare).

O Conf significa que, se o apt-get dist-upgrade foi executado, os pacotes marcados com Conf teriam apenas seus scripts de configuração executados, ou seja, o mesmo que dpkg-reconfigure ? A descrição do man pages de Inst diz "descompactar", isso me sugere que o pacote será baixado e descompactado, mas isso não parece fazer muito sentido.

Qual é o significado de "Inst" e "Conf"?

    

Answer 1

Você precisa olhar a página do manual para dpkg para as "operações representadas do dpkg".

Trechos de man dpkg :

Instalar

-i, --install package-file...
      Install the package. If --recursive or -R option is specified, package-file must refer to a directory instead.

      Installation consists of the following steps:

      1. Extract the control files of the new package.

      2. If another version of the same package was installed before the new installation, execute prerm script of the old package.

      3. Run preinst script, if provided by the package.

      4. Unpack the new files, and at the same time back up the old files, so that if something goes wrong, they can be restored.

      5. If another version of the same package was installed before the new installation, execute the postrm script of the old package. Note that
         this script is executed after the preinst script of the new package, because new files are written at the same time old files are removed.

      6. Configure the package. See --configure for detailed information about how this is done.

Descompacte

--unpack package-file...
       Unpack the package, but don't configure it. If --recursive or -R option is specified, package-file must refer to a directory instead.

Configurar

--configure package...|-a|--pending
       Configure a package which has been unpacked but not yet configured.  If -a or --pending is given instead of package, all unpacked but uncon‐
       figured packages are configured.

       To reconfigure a package which has already been configured, try the dpkg-reconfigure(8) command instead.

       Configuring consists of the following steps:

       1. Unpack the conffiles, and at the same time back up the old conffiles, so that they can be restored if something goes wrong.

       2. Run postinst script, if provided by the package.

Note que Install executa Unpack e Configure , e é por isso que eles são listados separadamente por apt-get .
