Ubuntu 20.04 (focal) Isaac ROS Buildfarm is not working

Robotics & Edge Computing Robotics - Isaac Isaac ROS

From last week we’re experimenting some problems when trying to connect to apt repositories of Isaac ROS.

Previous Repository

Previously we used this repo:

deb https://isaac.download.nvidia.com/isaac-ros/ubuntu/main focal main

But when trying to connect to to it says it’s not available (some weeks ago we used to use it without problem):

Command:

# Command
curl -I https://isaac.download.nvidia.com/isaac-ros/ubuntu/main/dists/focal/Release

Response (404 not found):

HTTP/2 404 
...

New Repository

Now I just learned that you updated the repo, acording to the Buildfarm guide: Isaac Apt Repository — isaac_ros_docs documentation

It should be now https://isaac.download.nvidia.com/isaac-ros/release-3

But when I try to curl this repo I get the same (for focal):

Command:

curl -I https://isaac.download.nvidia.com/isaac-ros/release-3/dists/focal/Release

Response (404 not found):

HTTP/2 404
...

But when testing jammy (ubuntu 22.04), it seems the repositories IS available, so it seems only the focal repos are down:

Command:

curl -I https://isaac.download.nvidia.com/isaac-ros/release-3/dists/jammy/Release

Response (200 OK):

HTTP/2 200
...

Acording to the documentation this buildfarm is mainly created for Ubuntu 20.04:

Hello camilo2, we are having the same issue since last Friday, Isaac ROS repo - release file error

Hello @sergei.poselenov, sadly I was internally notified that the Ubuntu 20.04 compatible repos stopped being mantained and won’t be up again.

Thanks for the heads-up camilo2. This is very unfortunate.

If the Isaac ROS packages aren’t maintained anymore that’s one thing, but removing the whole ROS2 Humble prebuild package ecosystem for Focal is more extreme. We would be forced to build all of ROS2 humble from source for Focal (20.04) if this apt repo is removed, until we can update to Jetpack 6, which will take time while waiting for custom kernels we use to be updated. ROS2 Humble is only compatible with Jammy (22.04), so we cant use the OSR buildfarm. This apt repo is for anyone running jetpack 5.x on a Jetson device regardless of the use of Isaac ros packages specifically.

Further to Henry’s point, Jetpack 6 isn’t even an option for Jetson Xavier devices.

Hi everyone,

Thank you, @henry.fuller. As you mentioned, the Isaac ROS 2.1 packages are no longer being maintained. Currently, the only options available are to either rebuild all packages from our source or upgrade to the latest version of Isaac ROS.

Best,
Raffaello

Thats very unfortunate. Is there anyway us jetpack 5.x users can lobby nvidia to keep the buildfarm running with a known sunset date before hand?
