<section end="History" />__FORCETOC__<section begin="Body" /> ==IntroductionManagement of prebuilt packages==During the development of custom applications, developers generally realize that they need to add libraries and other software packages to the root file systems to make their code run properly. If these packages are prebuilt, developers can install them onto the root file system very easily. By configuring the target as described in this document, they achieve a user experience similar to the one you have with a desktop Linux distro such as Ubuntu. DESK-MP1-L uses by default the <code>deb</code> package format. As such, [https://itsfoss.com/apt-command-guide/ apt commands] can be used for package management. Prebuilt packages are provided by [https://yocto.dave.eu/desk-mp1-l-1.0.01/ this repository] that DAVE Embedded Systems makes available for its customers. === 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-MP1-L. ====Configuring <code>apt</code>====Edit the file <code>/etc/apt/apt.conf</code> like this:<pre>root@desk-mp1:~# cat /etc/apt/apt.confAPT::Architecture "armhf";APT::Get::AllowUnauthenticated "true";Acquire::Languages "none";</pre> Edit the file <code>/etc/apt/sources.list.d/debian-10.list</code> like this:<pre class="board-terminal">root@desk-mp1:~# cat /etc/apt/sources.list.d/debian-10.listdeb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ all/deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ cortexa7t2hf-neon-vfpv4/deb [trusted=yes] http://yocto.dave.eu/desk-mp1-l-1.0.1/ desk_mp1/</pre> Execute the following commands in order to re-create the ''apt'' cache based on the new server's list: <pre>rm -rf /var/lib/apt/lists/*apt-get cleanapt-get update</pre> <pre class="board-terminal">root@desk-mp1:~# rm -rf /var/lib/apt/lists/*root@desk-mp1:~# apt-get cleanroot@desk-mp1:~# apt-get update The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA).The detailed content licenses can be found at https://wiki.st.com/stm32mpu/wiki/OpenSTLinux_licenses. Ign:1 http://yocto.dave.eu/desk-mp1-l-1.0.1 all/ InReleaseIgn:2 http://yocto.dave.eu/desk-mp1-l-1.0.1 cortexa7t2hf-neon-vfpv4/ InReleaseIgn:3 http://yocto.dave.eu/desk-mp1-l-1.0.1 desk_mp1/ InReleaseGet:4 http://yocto.dave.eu/desk-mp1-l-1.0.1 all/ Release [1215 B]Get:5 http://packages.openstlinux.st.com/4.1 kirkstone InRelease [3459 B]Get:6 http://yocto.dave.eu/desk-mp1-l-1.0.1 cortexa7t2hf-neon-vfpv4/ Release [1235 B]Get:7 http://yocto.dave.eu/desk-mp1-l-1.0.1 desk_mp1/ Release [1220 B]Ign:8 http://yocto.dave.eu/desk-mp1-l-1.0.1 all/ Release.gpgIgn:9 http://yocto.dave.eu/desk-mp1-l-1.0.1 cortexa7t2hf-neon-vfpv4/ Release.gpgIgn:10 http://yocto.dave.eu/desk-mp1-l-1.0.1 desk_mp1/ Release.gpgGet:11 http://yocto.dave.eu/desk-mp1-l-1.0.1 all/ Packages [158 kB]Get:12 http://yocto.dave.eu/desk-mp1-l-1.0.1 cortexa7t2hf-neon-vfpv4/ Packages [4123 kB]Get:13 http://packages.openstlinux.st.com/4.1 kirkstone/untested armhf Packages [1251 kB]Get:14 http://yocto.dave.eu/desk-mp1-l-1.0.1 desk_mp1/ Packages [238 kB]Get:15 http://packages.openstlinux.st.com/4.1 kirkstone/updates armhf Packages [30.9 kB]Get:16 http://packages.openstlinux.st.com/4.1 kirkstone/main armhf Packages [684 kB]Fetched 6492 kB in 9s (716 kB/s)Reading package lists...

In any case, a simple network configuration can be done according to the [[DESK-MP1-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>graphviz</code>: <pre class="board-terminal">root@desk-mp1:~# apt-get install graphvizReading package lists...
