Uninstall a Patch

If you updated the agent using the patch installer, you can manually uninstall the most recent patch update. After you uninstall the patch, the agent reverts to the previous version.

Follow these steps:

1. Stop the agent:
   • On UNIX:

     agent_install_dir/cybAgent -s
     

   • On Windows:

     agent_install_dir/cybAgent.exe -s
     

   agent_install_dir

   Specifies the path to the directory where the agent is installed.

2. Make a copy of the agent directory:
   • On UNIX:

     cp -r agent_install_dir agent_install_dir.backup
     

   • On Windows:

     xcopy agent_install_dir agent_install_dir.backup /s 
     

3. Identify the last installed patch in the following directory:
   • On UNIX:

     cd agent_install_dir/patches
     

   • On Windows:

     cd agent_install_dir/patches
     

4. Copy the contents of the last installed patch to the agent installation directory:
   • On UNIX:

     cp -r agent_install_dir/patches/patch_id agent_install_dir
     

   • On Windows:

     xcopy agent_install_dir/patches/patch_id agent_install_dir /s 
     

   patch_id

   Specifies the last installed patch file.

5. Delete the last installed patch from the patches directory:
   • On UNIX:

     rm -r agent_install_dir/patches/patch_id
     

   • On Windows, remove patch_id from the agent_install_dir/patches directory.

   The patch is uninstalled successfully. You can now restart the agent.
