I am trying to modify the iso file using below code, but getting the error “msg”: “Failed to delete iso file /boot.cfg with error: Assigned an extent beyond the ISO (214605 \> 214603)”}

unable to find any article. Can anyone help me to fix the issue?  
I am on Centos 9 Stream and Python 3.9.17  
pycdlib==1.14.0

```auto
  - name: Modify source ISO from {{ file_path }} and copy to destination
    community.general.iso_customize:
      src_iso: "{{ isosrc}}/{{ src_iso_file }}"
      dest_iso: "{{ iso_path }}/{{ item.servername }}.iso"
      delete_files:
        - "boot.cfg"
        - "EFI/BOOT/BOOT.CFG"
      add_files:
        - src_file: "{{ file_path }}/{{ item.servername }}/BOOT.CFG"
          dest_file: "BOOT.CFG"
        - src_file: "{{ file_path }}/{{ item.servername }}/BOOT.CFG"
          dest_file: "EFI/BOOT/BOOT.CFG"
    loop: "{{ hostName }}"

```

Some ISO files (e.g. VMware ESXi) have an unusual path table extent structure, which is the cause of your problem.

This is already addressed in upstream `pycdlib` repository, but the fix is not released as versioned pip module yet: [Assigned an extent beyond the ISO · Issue #106 · clalancette/pycdlib · GitHub](https://github.com/clalancette/pycdlib/issues/106)

So install latest `pycdlib` from GitHub and try your playbook again:

```bash
pip install git+https://github.com/clalancette/pycdlib.git

```
