1. Overview
cPanel & WHM includes a wide range of third-party software used for various system functions. Many of these applications are distributed under open-source licenses. WebPros International, LLC provides copies of all applicable licenses on your server and ensures that source packages (SRPMs) remain publicly available.
2. License Information
You can find all third-party license agreements in the following directory:
/usr/local/cpanel/3rdparty/share/
For example, the file:
/usr/local/cpanel/3rdparty/share/common-licenses/LGPL-2
contains the GNU Lesser General Public License version 2.
3. Find License Information for a Specific Package
To determine which license a third-party application uses, check the following file:
/usr/local/cpanel/3rdparty/share/name/copyright
where name represents the template or package name.
Note: Some packages are distributed under multiple licenses, so you may see several License entries.
4. Find a Source Package (SRPM)
To locate the SRPM for a third-party package, follow these steps:
- Navigate to the cPanel package update server.
- Open the directory for the version of cPanel & WHM that shipped the package.
- Enter the
src/directory to view all SRPMs.
For example, Perl’s SRPM is available at:
http://httpupdate.cpanel.net/RPM/11.46/src/
as the file:
cpanel-perl-514.5.14.4-4.cp1146.src.rpm
5. Third-Party Software Lists
Each version’s Release Notes includes a list of all third-party software shipped with that version.
6. Third-Party Software End of Life (EOL) Policy
WebPros International, LLC maintains an official EOL policy for third-party software and operating systems. An EOL date indicates when support for that software version ends.
Software without an explicit EOL date remains supported as long as demand and business needs continue.
6.1 When a Vendor Ends Support
When a vendor stops providing updates for their software, cPanel & WHM will:
- Remove the software from cPanel & WHM.
- Notify users about the upcoming removal.
- Stop providing technical support for the software.
- Recommend upgrading to a supported version when possible.
7. Operating System EOL Policy
An OS vendor determines the EOL date for their operating system. This is the period during which patches and updates are provided.
cPanel supports operating systems for their full lifecycle. However, in some cases, cPanel may discontinue support for an OS in new versions of cPanel & WHM before the OS reaches its vendor-defined EOL.
Servers running Ubuntu follow a slightly different support cycle:
- cPanel supports only LTS versions of Ubuntu.
- Support for a new Ubuntu LTS version begins when a new cPanel LTS version is released.
- When a new Ubuntu version is supported, the previous version becomes deprecated.
Example: cPanel & WHM version 118 is the last version supporting Ubuntu 20.04. To upgrade beyond version 118, you must upgrade the OS to Ubuntu 22.04 or later.
8. What Happens When an OS Reaches EOL?
When an OS reaches EOL:
- The OS continues to function normally.
- Existing cPanel & WHM installations continue working.
- Support continues only through the last cPanel LTS version that supports the OS.
You will be unable to:
- Perform fresh installations of cPanel & WHM.
- Upgrade to newer versions of cPanel & WHM.
- Receive OS-specific fixes or security patches.

10. What Should You Do If Your OS Has Reached EOL?
We recommend scheduling an OS upgrade as soon as possible. Depending on your environment, you may:
- Upgrade the OS directly (if supported by the vendor).
- Provision a new cPanel server and migrate accounts and configurations.
- Transfer your license to the new server.
Example: cPanel does not support installations on Amazon Linux 2. Users running Amazon Linux 1 should migrate to AWS Marketplace instances.
For assistance, contact your technical support provider or visit the cPanel Support page.
Conclusion
cPanel & WHM provides extensive third-party software support and maintains clear EOL policies to ensure system stability and security. Understanding license locations, SRPM sources, and OS support timelines helps administrators maintain a reliable hosting environment.
