New page

[http://code.google.com/p/opkg/ OPKG] (short for '''O'''pen '''P'''ac'''K'''a'''G'''e Management) is a leightweight [http://en.wikipedia.org/wiki/Package_management_system package management system] for [https://en.wikipedia.org/wiki/Embedded_system embedded systems]. OPKG is a fork of [[IPKG (en)|IPKG]].)

The package management in the shell is a powerful tool, and offers many possibilities.

This article explains how to search / install / remove packages and some more interesting commands which offers OPKG. If you want to learn all options of OPKG, enter following command in the [[Shell (en)|Terminal]]:

opkg

== Install packages via internet ==
To be able to install a package, the [http://en.wikipedia.org/wiki/Software_repository feed] defined in the <code>/etc/opkg</code>, should be updated. If this is not done, the installation will be terminated with the error message: <code>Unknown package ....</code>. Always enter the following command before installing:
<syntaxhighlight>
opkg update
</syntaxhighlight>

{{Warnung|Be careful when integrating 3rd party package feeds. If the feed is not available, or not maintained correctly, upgrading the firmware or installing packages will fail!}}

=== Installation ===
The installation of a package is done with the following command:

opkg install $package_name

=== Search package ===
There are different ways to search a package. First of all the package management offers the option '''search''', but unfortunately this option doesn't work quite well.

opkg list | grep search_term

It's also possible to use an asterisk symbol as wildcard in the search term.

opkg list *webadmin*

=== Deinstallation ===
Removing a package is done like this:

opkg remove $package_name

== Install local packages ==
Uupdate the package lists, this way the dependencies (if required) for the package will be resolved and installed. The command is:

opkg update

=== Installation of one package ===
Use the following command for the installation.

opkg install /tmp/$file_name_of_the_package

=== Installation of multiple packages ===
The installation of multiple packages is also easy, once all files are copied with [[FTP (en)|FTP]] in the directory
opkg install /tmp/*.ipk

=== Deinstallation ===
The removal of a package is also done with the package name (without the version and the extention ipk) and the following command:

opkg remove $package_name

== Other interesting commands ==

=== Update sources ===
'''Always''' update the sources before any package manipulation (e.g. installation, search, download of packages), with the command:

opkg update

=== Upgrade Firmware ===
With the following command it's possible to install all available updates for your Dreambox.

opkg upgrade

=== Chain commands ===
With two "and" symbols (&&) it's possible to chain commands. This way the second command is executed, as soon as the first is succesfully performed. The following command is very often used, to update the sources and the firmware.

opkg update && opkg upgrade

=== Install multiple packages from the feeds ===

opkg install $package_name $package_name $package_name $package_name

=== Deinstall multiplpe packages ===

opkg remove $package_name $package_name $package_name $package_name

=== Show all available packages from the feeds ===

opkg list

=== Show all installed packages ===

opkg list-installed

=== Show installed package ===
The following command can be used to search for an installed package. If the package is installed the name is shown with the version number. If no output is displayed, the package is not installed ot the name of the package is wrong.

opkg list-installed $package_name

=== Show upgradable packages ===

opkg list-upgradable

=== Show packages page by page ===
Packages can be shown with the command <code>[http://en.wikipedia.org/wiki/More_%28command%29 more]</code>. Use the {{Taste|space}} or {{Taste|↵ Enter}} to continue.

opkg list | more
opkg list-installed | more
opkg list-upgradable | more

=== Install packages from a website ===
Packages can be installed directly from a web adress, e.g. with following command.

opkg install http://www.yyy.com/zzzz/$package_name.ipk

=== Download package from the feed ===

opkg download $package_name

=== Show package information ===

opkg info $package_name

=== Show package dependencies ===
Lists packages which are '''mandatory''' for an installation.

opkg depends $package_name

=== Show packages which require the package as dependency ===
Shows the packages which have the <code>$package_name</code> as required dependency.

opkg whatdepends $package_name

=== Simulate package installation ===
Loads the package and simulates the installation. Ideal to check if an installation would be performed succesfully.

opkg --noaction $package_name

=== Deinstall package with all dependencies ===
Removes a package and all installed dependencies.

opkg --autoremove $package_name

=== Set package on hold ===
Prevent an update of a package (using the flag <code>'''hold'''</code>).

opkg flag hold $package_name

=== Release package ===
Release a package which is on '''<code>hold</code>'''.

opkg flag user $package_name

=== List the compatible package architectures ===
Shows the content of the file <code>/etc/opkg/arch.conf</code>.

opkg print-architecture

== Tips and Tricks ==

=== Proxy Server ===
When using a [http://en.wikipedia.org/wiki/Proxy_server Proxy Server] to install packages, edit the configuration file <code>/etc/opkg/opkg.conf</code>. The entries should be self explaining ;)

=== Unpack IPK packages ===
Packages can be unpacked on a home computer. With Linux no extra tools are required, for Windows users the programm [http://www.7-zip.org/ 7-Zip] can be used. And for MAC users [http://macitbetter.com/ BetterZIP].

=== Write text file with list of installed packages ===
With following command it's possible to create a list of installed packages, and write the list in a text file.

The list with the name '''e2plugins''' can be found in the directory <code>/home/root</code>. This file can be used to show the installed packages, and reinstall the plugins after a new image was flashed. Of course you have to copy the list from the Dreambox on your computer (e.g. using [[FTP (en)|FTP]]).

opkg list-installed *extensions* | awk '{ print $1 }' > /home/root/e2plugins

Install the content of the list is possible with following command. Make sure the text file is in the directory <code>/home/root</code>. And of course the packages should be available on the feeds.

opkg update && opkg install $(cat /home/root/e2plugins)

An other method to install multiple packages is described in the chapter [[OPKG (en)#Install multiple packages from the feeds|other interesting commands]]. But you need to know the names of the packages.

opkg update && opkg install $paketname $paketname $paketname $paketname
