7088 msgid "Anatomy of the Package System"
7089 msgstr "Anatomia del sistema di pacchettizzazione"
7095 "The Debian packaging system has a large amount of information associated "
7096 "with each package to help assure that it integrates cleanly and easily into "
7097 "the system. The most prominent of its features is the dependency system."
7099 "Il sistema di pacchettizzazione di Debian contiene un gran numero di "
7100 "informazioni associate a ciascun pacchetto, per assicurarsi che si integri "
7101 "facilmente ed in maniera pulita nel sistema; la più importante di esse è il "
7102 "sistema di dipendenze."
7108 "The dependency system allows individual programs to make use of shared "
7109 "elements in the system such as libraries. It simplifies placing infrequently "
7110 "used portions of a program in separate packages to reduce the number of "
7111 "things the average user is required to install. Also, it allows for choices "
7112 "in mail transport agents, X servers and so on."
7114 "Il sistema di dipendenze permette ai singoli programmi di fare uso degli "
7115 "elementi condivisi del sistema, quali le librerie; per ridurre il numero di "
7116 "elementi che l'utente medio debba installare, le porzioni di programmi che "
7117 "non vengono usate spesso vengono poste in pacchetti separati. Inoltre, è "
7118 "possibile avere più di una scelta per cose quali i programmi di posta "
7119 "elettronica, i server X e così via."
7125 "The first step to understanding the dependency system is to grasp the "
7126 "concept of a simple dependency. The meaning of a simple dependency is that a "
7127 "package requires another package to be installed at the same time to work "
7130 "Il primo passo per capire il sistema di dipendenze è la comprensione del "
7131 "concetto di dipendenza semplice: un pacchetto richiede che un altro sia "
7132 "installato insieme ad esso per poter funzionare."
7138 "For instance, mailcrypt is an emacs extension that aids in encrypting email "
7139 "with GPG. Without GPGP installed mailcrypt is useless, so mailcrypt has a "
7140 "simple dependency on GPG. Also, because it is an emacs extension it has a "
7141 "simple dependency on emacs, without emacs it is completely useless."
7143 "Ad esempio, mail-crypt è un'estensione di emacs che aiuta a criptare le mail "
7144 "con PGP. Se PGP non è installato, mail-crypt è inutile, quindi mail-crypt ha "
7145 "una dipendenza semplice da PGP. Inoltre, dato che si tratta di un'estensione "
7146 "di emacs, mail-crypt dipende anche da emacs, senza il quale è totalmente "
7153 "The other important dependency to understand is a conflicting dependency. It "
7154 "means that a package, when installed with another package, will not work and "
7155 "may possibly be extremely harmful to the system. As an example consider a "
7156 "mail transport agent such as sendmail, exim or qmail. It is not possible to "
7157 "have two mail transport agents installed because both need to listen to the "
7158 "network to receive mail. Attempting to install two will seriously damage the "
7159 "system so all mail transport agents have a conflicting dependency with all "
7160 "other mail transport agents."
7162 "L'altro tipo di dipendenza importante da capire è la dipendenza di "
7163 "conflitto; con questa, un pacchetto che venga installato insieme ad un altro "
7164 "pacchetto non funziona, e si hanno seri problemi al sistema. Come esempio, "
7165 "si consideri un programma di trasporto della posta, quale sendmail, exim o "
7166 "qmail: non è possibile averne due contemporaneamente, perché entrambi hanno "
7167 "bisogno di restare in ascolto sulla stessa porta di rete per ricevere la "
7168 "posta. Tentare di installarne due danneggerebbe seriamente il sistema, "
7169 "quindi ciascun programma di trasporto della posta ha una dipendenza di "
7170 "conflitto con tutti gli altri."
7176 "As an added complication there is the possibility for a package to pretend "
7177 "to be another package. Consider that exim and sendmail for many intents are "
7178 "identical, they both deliver mail and understand a common interface. Hence, "
7179 "the package system has a way for them to declare that they are both mail-"
7180 "transport-agents. So, exim and sendmail both declare that they provide a "
7181 "mail-transport-agent and other packages that need a mail transport agent "
7182 "depend on mail-transport-agent. This can add a great deal of confusion when "
7183 "trying to manually fix packages."
7185 "Come ulteriore complicazione, c'è la possibilità che un pacchetto voglia "
7186 "prendere il posto di un altro; ad esempio, exim e sendmail per molte cose "
7187 "sono identici, dato che entrambi gestiscono la posta e comprendono "
7188 "un'interfaccia comune, quindi il sistema di pacchettizzazione deve "
7189 "dichiarare che sono entrambi agenti di trasporto della posta, e che gli "
7190 "altri pacchetti a cui serve uno dei due devono dipendere da un pacchetto "
7191 "fittizio agente-di-trasporto-della-posta. Quando si modificano a mano i "
7192 "pacchetti, questo può portare a moltissima confusione."
7198 "At any given time a single dependency may be met by packages that are "
7199 "already installed or it may not be. APT attempts to help resolve dependency "
7200 "issues by providing a number of automatic algorithms that help in selecting "
7201 "packages for installation."
7203 "In ciascun momento una singola dipendenza può essere soddisfatta o meno dai "
7204 "pacchetti già installati; APT cerca di risolvere i problemi di dipendenze "
7205 "con un buon numero di algoritmi automatici, che aiutano a selezionare i "
7206 "pacchetti da installare."
7212 "<prgn>apt-get</prgn> provides a simple way to install packages from the "
7213 "command line. Unlike <prgn>dpkg</prgn>, <prgn>apt-get</prgn> does not "
7214 "understand .deb files, it works with the package's proper name and can only "
7215 "install .deb archives from a <em>Source</em>."
7217 "<prgn>apt-get</prgn> fornisce un modo semplice di installare i pacchetti "

7227 "the http_proxy environment variable first, see sources.list(5)</p></"
7228 "footnote> thing that should be done before using <prgn>apt-get</prgn> is to "

7717 "l'installazione di un pacchetto fallisce, ed in questo caso è possibile che "
7718 "un pacchetto venga scompattato senza che tutti quelli da cui dipende siano "
7725 "The second situation is much less serious than the first because APT places "
7726 "certain constraints on the order that packages are installed. In both cases "
7727 "supplying the <tt>-f</tt> option to <prgn>apt-get</prgn> will cause APT to "
7728 "deduce a possible solution to the problem and then continue on. The APT "
7729 "<prgn>dselect</prgn> method always supplies the <tt>-f</tt> option to allow "
7730 "for easy continuation of failed maintainer scripts."
7732 "La seconda possibilità è meno seria della prima, dato che APT gestisce "
7733 "l'ordine di installazione dei pacchetti; in entrambi i casi l'opzione <tt>-"
7734 "f</tt> di <prgn>apt-get</prgn> gli farà trovare una soluzione e lo farà "

7751 "fallisca, subito o durante la sequenza di installazione. In entrambi i casi "

8003 "conseguenza di un'installazione non andata a buon fine. La linea finale "
8004 "indica i requisiti di spazio dell'installazione: i primi due numeri indicano "
8005 "rispettivamente il numero di byte che devono essere trasferiti da posizioni "
8006 "remote, ed il secondo la dimensione totale di tutti gli archivi necessari "

8209 "Normally APT requires direct access to a Debian archive, either from a local "
8210 "media or through a network. Another common complaint is that a Debian "
8211 "machine is on a slow link, such as a modem and another machine has a very "
8212 "fast connection but they are physically distant."
8218 "The solution to this is to use large removable media such as a Zip disc or a "
8219 "SuperDisk disc. These discs are not large enough to store the entire Debian "
8220 "archive but can easily fit a subset large enough for most users. The idea is "
8221 "to use APT to generate a list of packages that are required and then fetch "
8222 "them onto the disc using another machine with good connectivity. It is even "
8223 "possible to use another Debian machine with APT or to use a completely "
8224 "different OS and a download tool like wget. Let <em>remote host</em> mean "
8225 "the machine downloading the packages, and <em>target host</em> the one with "
8226 "bad or no connection."
8232 "This is achieved by creatively manipulating the APT configuration file. The "
8233 "essential premise to tell APT to look on a disc for it's archive files. Note "
8234 "that the disc should be formated with a filesystem that can handle long file "

8247 "basic idea is to place a copy of the status file on the disc and use the "
8248 "remote machine to fetch the latest package files and decide which packages "

8268 msgid "The configuration file"
8274 "The configuration file should tell APT to store its files on the disc and to "
8275 "use the configuration files on the disc as well. The sources.list should "
8276 "contain the proper sites that you wish to use from the remote machine, and "
8277 "the status file should be a copy of <em>/var/lib/dpkg/status</em> from the "
8278 "<em>target host</em>. Please note, if you are using a local archive you must "
8279 "use copy URIs, the syntax is identical to file URIs."
