<![CDATA[Unable to install the VOXL SDK]]>I am trying to install the VOXL SDK on my Sentinel drone.

Using the install.sh script inside the VOXL SDK download completes the flashing of the system image successfully but fails to install the voxl-suite by spitting out the following error.

Ign:4 file:/data/voxl-suite-offline-packages ./ Translation-en

My guess is that there's something wrong with the apt sources listing inside /etc/apt/, as I see the same errors when I do sudo apt update inside the sentinel drone.

Can anyone please let me know how to solve this?
Or how can I retrieve the factory apt source files?

UPDATE

voxl-configure-mpa solved this particular issue.

Following these instructions.

Still, I'm facing further issues.

For some reason, all the services were Disabled and Not Running when I checked through voxl-inspect-services. Is this normal?

I manually enabled and started some, as shown below, but I am unable to start the voxl-vision-hub and the voxl-qvio-server services. How can I bring them up?

I would do the following to fully wipe / re-flash your system:

cd voxl2_SDK_1.0.0
cd system-image
./flash-system-image.sh -f

cd ..
cd voxl-suite
./offline-install.sh

UPDATE

I solved this issue by adding the following line inside the offline-install.sh at line 92

adb shell "cd $PKG_DIR/ && gunzip Packages.gz"

but then I am facing the following error while installing the voxl-suite

                PLEASE POWER CYCLE YOUR VOXL

This does ends up with the installation of VOXL SDK, and I can even access the camera server, but there are issues with MPA and I am unable to connect to QGC.

Help please.
