The Citrix ICA Client (Receiver) 13 .deb package has some known issues. How do I make changes to the package? I need to remove some dependencies and change the install script.

I am answering this question myself because others may find this information useful. This Q&A was inspired about another one: How do I install Citrix ICA Client (Receiver) 13 on Debian 64-bit Linux?

  1. Create a temp directory and copy the .deb file to it.
  2. Extract the .deb file: ar vx archive.deb
  3. Three files will appear:
    • debian-binary: Do not touch
    • control.tar.gz: Config and scripts to install and uninstall
      • This file may have a different extension, depending on the compression format used.
    • data.tar.gz: Files to be installed
      • This file may have a different extension, depending on the compression format used.

Both *.tar.gz files may different extensions, depending on the compression format used. The .deb format supports a few different ones. Also both *.tar.gz files are tarbombs, so all the files will explode to the same path. Better to create a temp directory, copy, then extract.

File control.tar.gz has two files good for hacking:

  • control: Contains package dependency list. You can add/remove dependencies.
  • postinst: Contains the post-installation script. You can add/remove commands.

Recreate the *.tar.gz files as: tar -czvf control.tar.gz * or (data.tar.gz)

Finally, create a new archive. Order is very important here: ar rv my_new_package.deb debian-binary control.tar.gz data.tar.gz

You can try your new package with these commands:

  • Uninstall existing package: apt-get remove $package_name
    • ... where $package_name is the name of your package, e.g., icaclient
  • Install new package: dpkg --install my_new_package.deb
