Hello, I just updated the system image to version 3 beta. And I accidentally erased the data partition on the voxl. Is it possible to get image of original data partition from the factory, the original that I got when I bought flight deck like all the pre-configuration files which were present in the data partition and also any other files necessary that comes included in untouched flight deck.

@Chad-Sweet
Yes I tried both setting it to true and false. But once you start launch camera and the terminated and try to launch again it does not launch.

@modaltb
I am using voxl-flight deck
cameras are same that comes with flight deck-> stereo camera, hires and optical flow camera

This is the voxl version currently in use in my setup

I am currently working with SNAV and followed this [https://docs.modalai.com/snapdragon-navigator/]

I was trying to rosdep update on some custom packages. But then ended up adding source directly to the workspace.

I get this error every other time. for the first launch it executed perfectly but subsequent lanches throw error. Basically if it run perfectly and if i interrupt it by pressing ctrl + c and than run again it starts saying could not load nodelet. And many a time it says could not open camera ID = 2. Unable to open camera.

I even tried setting it as slave and not master as recommended over here [https://docs.modalai.com/voxl-cam-ros/](link url)

but after showing Monotonic offset it throws error

I am able to get rosdep working by updating ca-certificates through this

update-ca-certificates
cp /etc/ssl/certs/ca-certificates.crt /usr/lib/ssl/certs

and setting SSL_CERT_FILE variable to point to ca-certificate path

export SSL_CERT_FILE=/usr/lib/ssl/certs/ca-certificates.crt

but now rosdep dos not detect OS used by Voxl

ERROR: Rosdep experienced an error: Could not detect OS, tried ['windows', 'ubuntu', 'slackware', 'rhel', 'qnx', 'osx', 'opensuse', 'opensuse', 'mint', 'linaro', 'gentoo', 'funtoo', 'freebsd', 'fedora', 'elementary', 'debian', 'cygwin', 'centos', 'arch']

Hello,
I am not able to init rosdep. When I do sudo rosdep init it keeps giving error

ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

I tried manually downloading 20-default.lit using wget and placing it inside /etc/ros/rosdep/sources.list.d/ directory and tried running rosdep update still it says connection timeout whereas these url are perfectly working when open through browser

I tried doing this updating certificates but it didn't work

update-ca-certificates
cp /etc/ssl/certs/ca-certificates.crt /usr/lib/ssl/certs

I am using voxl-flightdeck and these are the versions of onboard images
