I cannot install the isaacROS package

I tried to install the isaacROS package, but I couldn’t.
isaac_ros_nvblox — isaac_ros_docs documentation

Until recently, I was able to run the demo by following the usual steps, but suddenly, it stopped working.

Could you please check it?

/workspaces/isaac_ros-dev$ sudo apt update &&
sudo apt-get install -y ros-humble-isaac-ros-nvblox && \
rosdep update && \
rosdep install isaac_ros_nvblox

I am having the same issue, trying to install the ros-humble-isaac-ros-dnn-image-encoder package. Was able to run this with no issues yesterday. Started facing it since this morning only.

sudo apt-get install ros-humble-isaac-ros-dnn-image-encoder

Hi all,

Thank you for your post, I can reproduce this issue. I’m forwarding to the engineers for a quick fix.

Best,
Raffaello

@k_m , @amanickapraveen Thank you for bringing this issue to our attention. We have redeployed the packages to our apt repo and I’ve confirmed that they’re available once again.

Please let me know if you continue to see problems downloading these Debian packages.
