Package Location Error—— “E: Unable to locate package ros-humble-isaac-ros-visual-slam”

[hjc0106]

When executing ./scripts/run_dev.sh ${ISAAC_ROS_WS} to launch the docker container, it failed due to network connection——"Err:31 http://ppa.launchpad.net/mosquitto-dev/mosquitto-ppa/ubuntu focal InRelease Cannot initiate the connection to ppa.launchpad.net:80 (2620:2d:4000:1::81). - connect (101: Network is unreachable) Could not connect to ppa.launchpad.net:80 (185.125.190.80), connection timed out". Perhaps it won't affect the installation of visual SLAM? Then I tried to sudo apt-get install -y ros-humble-isaac-ros-visual-slam, package location error occurred——“E: Unable to locate package ros-humble-isaac-ros-visual-slam”. I am running on Ubuntu 22.04.

The full log is provided below: Run ./scripts/run_dev.sh ${ISAAC_ROS_WS}

Seems like this is a recent problem? See as well -- https://forums.developer.nvidia.com/t/run-dev-sh-failed-to-build-base-image-file-has-unexpected-size/277156/6

Hi @hjc0106 , I am facing the same issue, were you able to solve this issue or did you find any workaround and also I am running setup.bash each time I run docker, I am trying to add the command to bashrc but each time a new container is created the old bashrc is getting removed. Please let me know if you can help me with these things.

Thank you.

Hello, could you share the full logs here? This looks like an intermittent failure.
