First, check the ROS Index or type apt search ros-distro in your linux terminal to determine whether the ros-package is available for your ros-distro. Then, type sudo apt-get install ros-distro-package_name to install that package. After that, you can verify that the package has been installed by typing sudo apt-get rospack list-names or sudo apt-get rospack listto show the directory of the installed package. To check if it's up-to-date, typesudo apt update`to download the latest version of the package.

In your case, package cv_camera is not supported for ros-humble yet.

The main problem reported by the OP is caused by the misconfiguration of the ROS package repositories.

You cannot install a ros-humble-... package from the ROS 1 package repositories. Regardless of whether it's released or not.

Yeah, I know that but when I typed this response, I was just trying to add on to your comment if the user ends up encountering an issue with installing a package even though the user installed from the correct ROS # package repository.

I'd at least mention #q320046 in that case.

Noted, I will keep in mind next time since I'm new to this community wiki. My bad.

There is no need to apologise.

this might not be the right place to ask, but do you have any tips on getting good at debugging? I get that it all comes down to being practical at the end of the day but I would like to know if there are other ways that would help too.

qilin_gundamenjoyer ( 2022-06-04 07:47:49 -0500 )edit

I'm not sure I understand your comment.

"Debugging" in what way specifically?

gvdhoorn ( 2022-06-04 08:58:45 -0500 )edit

learning how to solve errors and knowing what error is the problem

You appear to be trying to use the ROS 1 package repository to install a ROS 2 package.

That doesn't work.

According to ros2/rolling/Installation: Ubuntu (Debian), the ROS 2 repository would be http://packages.ros.org/ros2/ubuntu, not http://packages.ros.org/ros/ubuntu.

I would suggest to verify you've correctly setup the ROS 2 repositories and followed the installation tutorial.

This is the same problem as in your other #q399935.

I tried solution from @javisshultz #q345764

the Q&A you link discusses a ROS 1 problem. It's not applicable to ROS 2.

Additionally:

Unable to locate package ros-humble-cv-camera

According to status_page/ros_humble_default.html?q=camera, cv_camera is not available in ROS 2 Humble.

I tried to solve the problem by repeating the curl and echo commands in the installation tutorial (https://docs.ros.org/en/humble/Instal...), but to no avail. When I run "sudo apt-get install ros-$(rosversion -d)-turtlesim", it fails to fetch. When I run "sudo apt-get update", one of the lines reads "E: The repository 'http://packages.ros.org/ros/ubuntu jammy Release' does not have a Release file."

The answer from https://answers.ros.org/question/4021... worked.
