Hi, I am trying to install p7zip-full library on my MangOH Red board with WP7702 module using SSH of Legato Dev Studio, but don’t know what command to use I tried “su apt-get install p7zip-full” it is saying no password to access user apt-get, I don’t understand what is the problem. Pls help me. ---

You can have a try on this: 1.download the yocto source and go to ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc 2.add the following line: IMAGE\_INSTALL\_append = " p7zip" 3.go to ./meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf change UBI\_ROOTFS\_SIZE ?= “48MiB” 1. Make the yocto image and download to the module ---

Thanks for the help. Sorry for asking it, where should I download yocto source from where and how. Make the yocto image and download to the module? how? please note I was trying to install p7zip-full from the SSH terminal of dev studio. I am not exactly understanding the steps mentioned by you. ---

You can download the yocto source of wp77 here [https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release-components/#sthash.3bihsAkp.dpbs](https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-latest-release-components/#sthash.3bihsAkp.dpbs) ---

Do you want me to download wp77xx latest firmware? I already have R9.1 and R11, latest is R12. Please note I don’t have MangOH virtual machine, all I am trying is through dev studio. ---

No, you need to download the yocto source. ---

Do you mean this " [SWI9X06Y\_02.32.02.00 Source](http://downloads.sierrawireless.com/AirPrime/WP77xx/Release12/Legato-Dist-Source-mdm9x06-SWI9X06Y_02.32.02.00.tar.bz2) (Based on Kernel 3.18 and Yocto 2.5)", but I think you need MangOH VM for it to edit and make the source which I don’t have. Is there any other method where I can install the p7zip through dev studio directly? ---
