Ubuntu 16.04 LTS (Xenial Xerus) reached the end of its five-year Expanded Security Maintenance (ESM) window in April 2026. If you are still running this Ubuntu version, it’s important to know your options. Read our blog post to learn more: canonical.com/blog/ubuntu-16… #Ubuntu #Security #LTS

How do you ensure that your LLM gives you relevant answers to your questions? Find the answer in our latest blog by Rob Gibbon, Product Manager at @Canonical. He takes a deeper look at what actually happens inside production-grade Retrieval Augmented Generation (RAG) systems, beyond the basic pattern. He explains how hybrid search models combine vector and keyword search to give broader recall, why reciprocal rank fusion (RRF) is often used to combine the results, and how reranking improves relevance before context reaches the LLM.

Less time spent on infrastructure, more time delivering business impact with AI systems. Learn more here: ubuntu.com/blog/nvidia-ne…

In software supply chain security, is the best code always the freshest? Daily rebuilds pull in every upstream change the moment it arrives, before anyone has had time to examine it. Zero CVEs doesn't always mean secure. It could mean unexamined. Security backporting patches vulnerabilities deliberately, without pulling in unreviewed upstream changes, and only ships what's already been inspected. Cool code is predictable code.

From 3 hours to 45 minutes. From operational fragmentation to stability. In our latest video case study, OEDIV explains how Ubuntu Pro helped reduce upgrade time by 60%, cut manual engineering work by 70%, and reduce complexity in open source security and support. Managing thousands of Linux systems for customers with strict security and compliance requirements, stability, and the ability to respond fast. With Ubuntu Pro, OEDIV gained broader open source security coverage, easier hardening, and a more scalable foundation for growth. Watch the video to see how Ubuntu Pro helped OEDIV simplify operations and unlock new opportunities: youtu.be/vG4TL1sofCA?si… #UbuntuPro #Linux #OpenSource

Today, April 12, marks the International Day of Human Space Flight.🚀 As humanity moves deeper into the stars, open source is quietly powering the infrastructure behind space exploration. Did you know the ESA - European Space Agency runs its mission operations on Canonical's open source portfolio including Kubernetes, Ceph and PosgreSQL? These missions span from wildfire tracking to collision avoidance and disaster response. 🔗 Dive deeper into the ESA case study in this keynote: youtu.be/3spacWa8YGo?si… Happy International Human Space Flight Day!

Did you know that by year three, data center operating expenditure (OpEx) often exceeds 50% of total cost of ownership (TCO)? Many organizations focus on hardware costs – capital expenditure (CapEx) – but long-term operational work often has a bigger impact on budgets. Patching, provisioning, and troubleshooting all take time, and traditional data center operations struggle to keep pace with the speed and scale of the public cloud. With Canonical MAAS, you can replace manual work with standardized, repeatable operations. Read the blog to learn how to bring cloud-like agility to your on-prem environment. 🔗 canonical.com/blog/effective… #OpenSource #Canonical #MAAS

Embedded devices are becoming harder to ship, maintain, and keep compliant. That’s why we’ve teamed up with Advantech, Avnet, and Witekio to address it together. Join us on April 9 at 6:00 PM CET / 12:00 PM ET / 9:00 AM PT for a practical session on building a coordinated hardware and software ecosystem. We’ll explore how OEM teams can reduce security risks, meet Cyber Resilience Act (CRA) requirements, and simplify long-term device lifecycle maintenance.
