Whenever you run your application on a cloud, you are pretty much giving the cloud provider complete access to your sensitive data. Even if you were to use full-disk encryption to protect the data on your disk, it still remains vulnerable when in use — when loaded into RAM or processed by the CPU.
So how do you ensure that your data remains secure even if the cloud infrastructure is compromised? How do you trust a VM that was launched by a compromised host environment? An environment where a malicious actor could have physical access to your allocated hardware.
Confidential computing aims to solve all of these problems and in this talk, we'll see how that is achieved. We'll explore potential threats and understand mitigation techniques — techniques like secure boot, measured boot, TPM-based full-disk encryption and hardware-based trusted execution environments. We'll see how Ubuntu is modified to support all of this.
In this workshop, we'll showcase, how to create a snap from scratch. We'll use real life examples, with known issues and problems users run into.
We'll also try to showcase how to integrate ffmpeg and webkitgtk into your snaps, how to detect which plugs to use and more.
This workshop will start with a guided quickstart tutorial, after which we have an interactive problem solving session where we help you build a snap for your favorite application.

Have you ever wondered where the packages for multiple architectures on Ubuntu are built, where the primary archives are maintained and published, or where PPAs are hosted? If you've ever searched or filed a bug for Ubuntu, you may already know the answer—Launchpad. Launchpad is a set of web services that help software developers collaborate. Setting up Launchpad used to be a long, error-prone process, taking about 60 minutes with many manual steps, which made it difficult for the community to fix annoying bugs or propose new features.
In this talk, I'll demonstrate how we reduced the setup time to around 5 minutes using LXD, LXD-Image-Builder, cloud-Init, and LXD profiles. By pre-caching dependencies and automating the setup, the process is now faster, reliable, and makes it easier to contribute back. Join me to learn how these tools can simplify your workflow!

Project Description
The ScaniVerse project is a pioneering initiative designed to streamline the installation and management of scanner drivers across different Linux distributions. By utilizing Snaps, the project enables the creation of distribution-independent packages, allowing scanner drivers to be easily installed on any system that supports snapd. Additionally, scanner applications can be containerized using OCI containers, facilitating their deployment on immutable operating systems. Key components of the project include the integration of scanner support into the PAPPL library, originally developed for printer applications. This integration supports multi-function devices and provides a unified driver format for both printers and scanners. The project also focuses on retrofitting legacy scanners to ensure continued support for older hardware.
Ubuntu is a collection of many software programs that function together. Sometimes, these applications may have more permissions than they actually need, which can make them a good target for attackers. For example, imagine you install a simple image viewer, but because of it's weak security settings, it can read your private documents, access the internet, or even modify system files. If an attacker was able to find a vulnerability in such an application, they could possibly use that to compromise the whole system.
Without proper restrictions, an application could accidentally or maliciously perform actions beyond what it should. AppArmor helps fix this by allowing us to define exactly what an application can and cannot do.
In this workshop, we will:
- Learn the basics of AppArmor and how it works.
- Understand how to check an application’s current permissions.
- Write a basic AppArmor profile to restrict an application’s access.
- Test the profile to see how it improves security.
- Learn how to troubleshoot and refine AppArmor profiles.
By the end of the workshop, we will be able to create AppArmor profiles that enhance the security of applications running on our system.
An AppArmor profile creates a shield around our application. It defines what files, network resources, and system capabilities the application can access. For example, if we define the following rule for the image viewer, it can only access the files that end with jpeg, jpg or png which significantly reduces the attack surface.

Monitoring is something every sysadmin or developer must consider, particularly when dealing with Linux-based systems such as Ubuntu. But most classic monitoring tools either don't provide enough information, or they slow down because they execute heavy agents or scripts. In this presentation, I'll demonstrate how we can do it differently by leveraging two strong tools: eBPF and Prometheus.
eBPF (extended Berkeley Packet Filter) is a capability integrated into current Linux kernels that allows us to execute little programs securely within the kernel itself. That way, we can observe what's going on way down in the system, stuff like system calls, network activity, and CPU consumption, without altering the apps in use or introducing a ton of overhead. It's fast, secure, and incredibly useful for observability.
Prometheus, however, is already a very popular open-source tool for monitoring and alerting. It collects metrics from different places and assists us in analyzing them through PromQL, its query language. Putting eBPF and Prometheus together, you get a very effective and granular method of monitoring your Ubuntu system, with real-time data and little performance overhead.
In this session, I'll take you through the process of how eBPF gathers metrics and how Prometheus is able to leverage those metrics to provide you with information about your system. We'll cover existing eBPF exporters, and I'll demonstrate how to get everything installed on an Ubuntu machine—from installing Prometheus to running an eBPF exporter.
There will also be a live demonstration, where we'll track things such as CPU utilization, memory, disk I/O, and network performance in real time. I'll write some PromQL queries, so the audience can see just how easy it is to go exploring and see what your system is doing.
I'll conclude by examining what's new in Prometheus, such as new features that further empower it for system monitoring. I'll discuss how these enhancements, when paired with eBPF, can better monitor Ubuntu machines and provide greater flexibility in monitoring system activity.
We invite community leaders across the world as panels who leads Ubuntu LoCos, Local FOSS communities and organization and also people who learned and grows through Ubunut and FOSS Community.
This session will show hands-on on how to do translation on both submission and review via Launchpad and also will showcase the Launchpad feature in general and also show new translation on Flutter.

In terms of offering thorough visibility and effective threat mitigation, typical security systems frequently fall short. Without changing kernel code, the Extended Berkeley Packet Filter (eBPF) is a potent technology that makes it possible to monitor kernel-level activity safely and effectively. This session examines how runtime protection, network security enforcement, and real-time observability offered by eBPF might improve security on Ubuntu systems. Measures like intrusion detection systems, antivirus software, and static firewalls are less efficient against contemporary attacks as a result of the sophistication of security threats. By offering a programmable method of real-time system behavior analysis without compromising kernel stability, eBPF tackles these issues. eBPF is a crucial tool for contemporary security observability and enforcement since it can examine system calls, network packets, and process events by executing sandboxed programs inside the Linux kernel.
The talk will focus on the integration of eBPF with Ubuntu, highlighting Ubuntu’s compatibility and ecosystem support for eBPF-based security applications. also include practical demonstrations of eBPF-based security tools on Ubuntu, showcasing how to use eBPF programs for monitoring system calls, filtering network traffic, and detecting suspicious activities. We will walk through real-world examples of deploying eBPF security tools such as Falco, Cilium, and BPFtrace, and demonstrate how they enhance security in Ubuntu environments.
Participants will have a thorough grasp of how to use eBPF to improve security in Ubuntu environments by the end of this session. They will acquire hands-on experience in deploying eBPF for anomaly detection, network protection, and security monitoring, allowing them to leverage this potent technology in their own security plans.

Instruction Set Architecture (ISA) forms the foundational blueprint of all computing systems. Historically, ISAs have been tightly coupled with specific manufacturers, leading to inconsistencies across platforms and requiring the redevelopment of software infrastructures for each architecture. Although some level of standardization has been achieved through dominant architectures such as x86 (led by Intel and AMD) and ARM, these remain proprietary and closed systems. This restricts openness, transparency, and collaborative progress—core principles of the open-source ecosystem.
In contrast, RISC-V has emerged as a transformative, open, and modular ISA that empowers developers, researchers, and hardware designers by eliminating licensing costs and vendor lock-in. This presentation explores the performance and compatibility of RISC-V when paired with Ubuntu, the flagship open-source operating system. Key metrics such as Boot Times, CPU Utilization across different RISC-V cores, Kernel Compilation Times, and Throughput in system-level tasks will be examined, along with comparisons to other mainstream architectures.
The session will highlight the performance and power efficiency of Ubuntu running on RISC-V hardware over other mainstream hardware, showcasing its viability in real-world applications. From ultra-low-power IoT devices to scalable edge computing platforms, Ubuntu on RISC-V demonstrates significant potential for enabling innovation across diverse industries.
This talk will trace the evolution of ISA development, examine Ubuntu's expanding support for the RISC-V ecosystem, and discuss the practical implications for developers and organizations adopting this architecture—supported by comparative benchmark data and real-world performance metrics.
