1. Introduction
Ubuntu 20.04 LTS (Focal Fossa) was released in April 2020 and has provided a stable environment for many users. However, its standard support is set to end in April 2025, making it essential to plan for the next steps.
In this article, we will explain the impact of Ubuntu 20.04 LTS reaching the end of support, available migration options, and upgrade procedures in detail.
2. What is Ubuntu’s Support System?
Ubuntu offers two types of versions: LTS (Long Term Support) releases and regular releases. Understanding the differences between them will help you choose the best course of action.
What is Ubuntu LTS?
LTS (Long Term Support) versions come with five years of standard support. During this period, security updates and bug fixes are provided, ensuring a stable environment. LTS versions are ideal for enterprises and server use, making them a popular choice among system administrators.
Difference Between Standard Support and ESM (Extended Security Maintenance)
Ubuntu LTS versions receive five years of standard support, but after that period, you can extend support further by subscribing to ESM (Extended Security Maintenance).
| Support Period | Details |
|---|---|
| Standard Support (5 years) | Security updates, bug fixes, kernel updates, and software maintenance |
| ESM (5 years) | Critical security updates only (No bug fixes or feature updates) |
While Ubuntu 20.04 LTS standard support will end in April 2025, you can continue receiving critical security updates until 2030 by opting for ESM.
3. Ubuntu 20.04 Support End Schedule
The support schedule for Ubuntu 20.04 LTS is as follows:
- April 2020 – Initial Release
- April 2025 – End of Standard Support
- April 2030 – End of ESM (Extended Security Maintenance)
After the support period ends, security patches will no longer be provided. Whether using Ubuntu for personal or server purposes, it’s crucial to consider migration or alternative measures.
4. What Happens After Support Ends?
Once the standard support for Ubuntu 20.04 LTS ends, the following impacts should be considered:
Risks of Stopping Security Updates
After support ends, any newly discovered vulnerabilities will no longer receive security updates. This increases the risk of attacks, especially for systems connected to the internet.
Impact on Compatibility, Business Operations, and Software
New software may no longer support Ubuntu 20.04 LTS. Additionally, continuing to use an unsupported OS in a server environment could lead to compliance issues.
Measures If You Continue Using Ubuntu 20.04
If you plan to keep using Ubuntu 20.04, consider implementing the following measures:
- Strengthen firewall settings
- Subscribe to ESM (Extended Security Maintenance)
- Use only trusted packages
- Plan for an OS upgrade
