[BUG] Claude's install.sh is broken for podman/docker image creation

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

I have been using the Dockerfile as seen in the Additional Information and the build.sh script to build a podman image (for more details please see the _Additional Information_ section) to do the following:

1. work around the fact that I run a non redhat-ubuntu distribution of linux native which is unsupported by anthropic and
2. to launch the claude client in a podman container to restrict access to Claude to only the files and directories currently under development.

I spent several hours asking opus 4.8 and sonnet for help to diagnose and fix an error in my code or workaround the bug, but it was fruitless. Asking opus to take ownership, file and monitor the bug report was also fruitless.

Could you please do the following:

1. Fix the regression in the install.sh script. During debugging we isolated it to the curl command in the container.
2. Allow the claude models to submit bug reports when they cannot resolve issues in the installer themselves and for them to monitor the report and notify me when there is activity.
3. Allow the claude models to test docker or podman image creation.

What Should Happen?

The image should be built correctly with the current claude terminal client installed.

Please notice the failure at STEP 7, this is reliably reproducible.

Steps to Reproduce

1. You should have a native linux install including your distribution's podman, bash and curl packages (although a similar behavior would be expected in docker).
2. Create a work directory, in my case I used ~/repo/claudecontainer, in linux I do mkdir ~/repo/claude_container.
3. pushd ~/repo/claude_container
4. mkdir images
5. create the docker/podman file named images/Dockerfile using a text editor or ide of your choice. Please see the Additional information section for the contents of the Dockerfile.
6. mkdir scripts
7. create the bash file named scripts/build.sh using a text editor of ide of your choice. Please see the Additional information section for the contents of the build.sh.
8. run the command bash -x scripts/build.sh to attempt the build.
9. Observe the failure.

Claude Model

None

Is this a regression?

Yes, this worked in a previous version
