You can use aptitude through a visual interface simply run aptitude or directly from the command line. The command line syntax used is very similar to the one used in apt-get.
For example, to install the foo package, you can run aptitude install foo. Note that aptitude is the preferred program for daily package management from the console. For more information, read the manual page aptitude 8 and install the aptitude-doc package. It enables you to install, upgrade and remove software packages in a user friendly way. Along with most of the features offered by aptitude, it also has a feature for editing the list of used repositories, and supports browsing all available documentation related to a package.
See the Synaptic Website for more information. When you want to perform a specific task it might be difficult to find the appropiate suite of packages that fill your need. The Debian developers have defined tasks , a task is a collection of several individual Debian packages all related to a specific activity. Tasks can be installed through the tasksel program or through aptitude. Typically, the Debian installer will automatically install the task associated with a standard system and a desktop environment.
Also, depending on your selections throughout the installation process, tasks might be automatically installed in your system. For example, if you selected a language other than English, the task associated with it will be installed automatically too and if the installer recognises you are installing on a laptop system the laptop task will also be installed. This program manipulates Debian archive. This is convenient for examining the contents of a package in a localized directory, without installing the package into the root file system.
Note that any packages that were merely unpacked using dpkg-deb --extract will be incorrectly installed, you should use dpkg --install instead. More information is given in the manual page dpkg-deb 1. We also provide a program called start-stop-daemon which is used to start daemons at boot time or to stop daemons when the runlevel is changed e. The same program is used by installation scripts when a new package containing a daemon is installed, to stop running daemons, and restart them as necessary.
I am building a script to automatically deploy a. I read that dpkg -i will upgrade the package if it is already installed, but if the check is dependent on the. So the way to go is removing and installing afterwards? This is the way I am currently doing it. Removing a package works by package name. Wanted to double check if there is no shortcut. The package is checked using the metadata it contains e.
Sign up to join this community. The best answers are voted up and rise to the top. Information displayed includes the group's mode auto or manual , the master and slave links, which alternative the master link currently points to, what other alternatives are available and their corresponding slave alternatives , and the highest priority alternative currently installed.
Each line contains up to 3 fields separated by one or more spaces. The first field is the alternative name, the second one is the status either auto or manual , and the last one contains the current choice in the alternative beware: it's a filename and thus might contain spaces.
The link group is updated. Defaults to «». This also sets the alternatives, installation and administrative directories to match. This option is only relevant with --config or --all. Can be overridden by the --altdir option. Can be overridden by the --admindir option. The first block contains the following fields: Name: name The alternative name in the alternative directory. Link: link The generic name of the alternative. Slaves: list-of-slaves When this field is present, the next lines hold all slave links associated to the master link of the alternative.
There is one slave per line. Each line contains one space, the generic name of the slave alternative, another space, and the path to the slave link. Status: status The status of the alternative auto or manual. Best: best-choice The path of the best alternative for this link group. Not present if there is no alternatives available.
Value: currently-selected-alternative The path of the currently selected alternative. It can also take the magic value none. It is used if the link doesn't exist. If you want to avoid spurious messages on upgrades, you can check for versions known to already include the diversion, or you can explicitly check whether the diversion already exists. There is no way for us to know enough to take over from here, so abort the upgrade.
Since failed upgrades can change the version number without configuration succeeding, the last version configured is not a reliable indication of whether the diversion is still around. If you want to avoid spurious messages, you can check for the diversion before removing it.
