==Introduction==
<section begin=body/>Since NXP BSP [https://www.nxp.com/webapp/Download?colCode=L5.4.24_2.1.0_LINUX_DOCS 5.4.24 ] Yocto release], [https://debian-handbook.info/browse/stable/sect.apt-get.html apt-get] has been added as a package manager for installing packages in the DUT (target machine).
As reported by NXP official documentation:
The default package management with Yocto Project is <code>rpm</code>. The i.MX distro now enables '''debian''' as the package management. This can be easily turned off by add PACKAGE_CLASSES <code>PACKAGE_CLASSES_*</code> set to <code>package_rpm </code> to the <code>local.conf </code> (or creating a custom distro without the debian package feed <code>PACKAGE_CLASSES = "package_rpm"</code>.
With the addition of the debian package feed, a sources.list can be added ''/etc/apt'' that links in Debian's package feed. This allows users to install packages not provided in the image without having to add them to a yocto image. Because this package feed is not generated by the i.MX Yocto build process, there is no guarantee each package will work with the right dependencies but it allows simpler tools to be provided. Software that is complex and has more dependencies on specific versions might have issues with an external package feed.
'''apt-get''' performs runtime package management of <code>.deb</code> packages. In order to use '''apt-get''' for runtime package management, you must perform an initial setup on the target machine for cases where the <code>PACKAGE_FEED_* </code> variables were not set as part of the image that is running on the target.
In principle, the adoption of the Debian package management should allow to use prebuilt package archives available for [http://ftp.debian.org/debian/README.html Debian distributions]. However, close attention should be paid when mixing packages of different distributions. For instance, Debian packages installed on a Yocto file system could not work. Even worse, '''they could interfere with existing packages and make these unusable'''.
This Application Note (AN) describes a way to apply the approach illustrated here to a Yocto distribution that makes use of Debian packetization. In other words, a local archive of Yocto-generated, prebuilt <code>.deb</code> packages is used in combination with the well known <code>apt-get</code> utility.
=== apt-get ===
The following instructions detail how to use apt-get for installing packages with Yocto repositories created by DAVE's build system for DESK-MX8M-L.
====Configuring <code>apt</code>for SBC-ORCA====
Edit the file <code>/etc/apt/apt.conf</code> like this:

=== Installing packages on target ===
We assume that network interface has been already configured for Internet access. In any case, a simple network configuration can be done according to the [[DESK-MX8M-L/Deployment/How_to_configure_the_network_interfaces#Static_IP_address | How to configure the network interfaces]] wiki page.
The target is finally ready to install new packages. The following example shows for instance the installation of <code>vimgraphviz</code>:
<pre class="board-terminal">
root@orcadesk-mx8mp:~# apt-get install vimgraphviz
Reading package lists... Done
Building dependency treeReading state information... DoneThe following additional packages will be installed: vim-common vim-help vim-syntax vim-tutor vim-vimrc
The following NEW packages will be installed:
After this operation, 0 B of additional disk space will be used.
</pre>
=== Other useful apt commands ===
==== List of configured software repositories ====
As shown before, the target is configured for accessing the Yocto repositories as listed in the <code>/etc/apt/sources.list.d</code> apt configuration directory:
<pre class="board-terminal">
root@desk-mx8mp:~# cat /etc/apt/sources.list.d/debian-10.list
deb [trusted=yes] http://yocto.dave.eu/imxdesk-mx8m-l-5.4.70-2.30.0/ all/deb [trusted=yes] http://yocto.dave.eu/imxdesk-mx8m-l-5.4.70-2.30.0/ aarch64armv8a-mx8mp/deb [trusted=yes] http://yocto.dave.eu/imxdesk-mx8m-l-5.4.70-2.30.0/ aarch64-mx8mpdesk_mx8mp/
</pre>
==== Search for packages ====
To search for an available package into the current configured channels use <code>apt-cache search</code>
<pre class="board-terminal">
root@desk-mx8mp:~# apt-cache search vim
vim - Vi IMproved - enhanced vi editor
vim-common - Vi IMproved - enhanced vi editor
vim-help - Vi IMproved - enhanced vi editor
vim-syntax - Vi IMproved - enhanced vi editor
vim-tutor - Vi IMproved - enhanced vi editor
vim-vimrc - Vi IMproved - enhanced vi editor
</pre>
==== List of installed packages ====
User can see the list of installed packages with <code>apt list dpkg --get-installedselections | sed 's:install$::'</code>(sed removes the ''install'' string from the output list)
