I'm currently following ROS2 Build Action tutorial: link text, and I'm stuck with the colcon build, the tutorial asks to add some lines to my CMakeLists and package files before building the package (The lines are encased with comments). Yet I'm getting errors that suggests I should remove some lines. I'll provide the errors and the files.

Error 1:

The error message says this:

Error(s) in package 'src/action_tutorials/package.xml':
Error(s):
- The manifest of package "action_tutorials" (with format version 2) must not contain the following tags: member_of_group

And indeed, we see you have a member_of_group element in your package manifest (as you should, otherwise the second error is shown).

But member_of_group (and several other elements) are only supported in version 3 manifests. See REP 149: Package Manifest Format Three Specification.

You have specced a version 2 manifest:

<package format="2">

For this to work, you should change that 2 in a 3.

I did as instructed, now I'm encountering this error:

Service interface 'unique_identifier_msgs/UUID' contains an unknown field type: unique_identifier_msgs/UUID action_goal_id

Message interface 'unique_identifier_msgs/UUID' contains an unknown field type: unique_identifier_msgs/UUID action_goal_id

Each one has a couple more error lines, but it doesn't fit in this comment, is there a possibility I can contact you somewhere else?

@gvdhoorn Clearly, we don't have the experience you do. You've told us what went wrong but, could you please tell us how to solve it? Thanks in advance.

@ianscottmoyes Please don't post answers that are not answers. I've converted your answer to a comment. For more, please see the support guidelines: http://wiki.ros.org/Support

@ianscottmoyes: I believe I did:

For this to work, you should change that 2 in a 3.

we don't know whether that fixed things though, as the OP never confirmed it was the solution.

I commented the result, I said it didn’t fix anything and I was still getting errors. I asked if I could contact you @gvdhoorn but I didn’t get a response back. Ultimately, I gave up on this endeavor since nothing I did would fix the errors.

Your comment under my answer seems to suggest changing the version of the package manifest actually did work.

You then report new problems, which should not be discussed in the same question, but for which you should post a new question.

I asked if I could contact you @gvdhoorn but I didn’t get a response back

I never respond to such requests, as 1) that's not how a public forum like ROS Answers is supposed to work, and 2) I don't want to do that. I'm happy to help on ROS Answers. I'm not a private troubleshooter.

I'm sorry, we're talking at cross purposes.

I didn't type a 2, or a 3.

I typed: colcon build

As instructed here: https://index.ros.org/doc/ros2/Tutori...

and got the error message mentioned in this post.

So, I typed. sudo apt install python3-colcon-common-extensions

As instructed here: https://index.ros.org/doc/ros2/Tutori...

& it doesn't change anything If you could please tell me how t solve this I would be very grateful?

Thanks in advance.

Ok, then I believe you should not be posting here.

The fact that you get a similar error message does not mean you're encountering the same problem.

Please post a new question, and clearly explain what you're doing and what goes wrong.

And include verbatim copy-pastes of error messages you see on the console (do not post screenshots).
