Introduction
Ubuntu 25.10 is making waves in the Linux community by integrating Chrony for improved Network Time Protocol (NTP) capabilities. This shift not only reinforces security through Network Time Security (NTS) but also aligns Ubuntu with major players like Red Hat Enterprise Linux and SUSE Linux Enterprise. Curious about what this means for your Ubuntu experience? Read on to discover the benefits and implications of this exciting transition.
What is Chrony and Why is Ubuntu Switching?
Chrony is a modern implementation of NTP, designed to provide highly accurate time synchronization in various conditions, including intermittent network connections. Unlike the previous systemd-timesync, Chrony offers enhanced security features through NTS, which safeguards against potential attacks such as spoofing and man-in-the-middle incidents.
The Benefits of Network Time Security (NTS)
By adopting NTS, Ubuntu 25.10 strengthens its resistance against cyber threats. These benefits are particularly pertinent for organizations relying on precise time synchronization for logs, audits, and security protocols. With NTS, time data is encrypted, ensuring that malicious actors cannot easily interfere with time signals.
Chrony’s Integration Timeline
The integration of Chrony in Ubuntu’s upcoming version, 25.10, is a critical step towards smarter and safer time management. Although Chrony can already be utilized with Ubuntu 25.04, the official switch will occur in early June 2024, positioning Chrony as the default NTP client.
Testing Chrony in Ubuntu 25.04
If you’re eager to experience Chrony’s capabilities before the official release, you can start using it now with Ubuntu 25.04. The client is already included in the main archive, making it easily accessible for all users. Just follow these commands to install it:
sudo apt update
sudo apt install chronyComparative Landscape: Chrony vs. systemd-timesync
While systemd-timesync has been a reliable component of previous Ubuntu releases, its capabilities pale in comparison to the advanced features offered by Chrony. This transition reflects a broader trend in the Linux ecosystem toward more secure and efficient time synchronization solutions.
Performance Considerations
Chrony excels in performance, particularly in environments with unstable network connections or significant time drift. Its algorithms allow for quicker adjustments, resulting in more consistent timekeeping. As networked devices proliferate, ensuring accurate timekeeping becomes increasingly essential, making Chrony a vital asset for modern computing.
Preparing for Ubuntu 25.10
If you’re a Linux enthusiast or an IT professional, preparing for the switch to Chrony is a prudent step. Familiarizing yourself with its configuration and operation will elevate your administration skills and enhance your environment’s security posture. You may find communities and resources on platforms like Stack Overflow or Linux forums useful for any specific questions you encounter.
Unique Tip: Enable Time Synchronization with NTS
After installing Chrony, consider enabling NTS by adding the following lines to your Chrony configuration file:

nts onThis step elevates your security, ensuring that synchronization messages remain encrypted.
Future Developments in Ubuntu Linux
The move to Chrony is just one of many innovations on the horizon for Ubuntu users. The community is continually pushing boundaries to enhance security, performance, and usability. Watching these developments can keep you at the forefront of Linux capabilities and trends.
Stay Informed
Keep an eye on Ubuntu mailing lists and the official Launchpad bug tracker for the latest updates and insights regarding Chrony’s adoption. Engaging with these resources will ensure you’re not just a bystander but an informed participant in the evolving Linux landscape.
FAQ
Question 1: What is the main advantage of Chrony over systemd-timesync?
The primary advantage of Chrony is its ability to provide more accurate time synchronization, especially in networks with variable connectivity. It also includes Network Time Security (NTS) features that enhance security against attacks.
Question 2: How can I start using Chrony on my current Ubuntu version?
You can install Chrony easily by running sudo apt install chrony in the terminal. Once installed, you can start managing time synchronization without waiting for the official Ubuntu 25.10 release.
Question 3: Will the change to Chrony affect my current system configuration?
The transition to Chrony should be smooth, as it is designed to replace systemd-timesync without significant disruption. However, reviewing and adapting your configuration settings is advisable to leverage Chrony’s full potential.
