The read-only base is intended to resist tampering and make installed software verifiable, but users can run only software packaged as snaps. Canonical is rebuilding image pipelines for continuous testing and daily builds, expected during the Ubuntu 27.04 cycle. Initial targets are browser-centric systems, developer workstations, and gaming machines, chosen partly because app availability is a major blocker. Open issues include independent component updates, permission prompts for confined snaps, and KDE Plasma support alongside GNOME. Ubuntu Core currently does not support classic snaps; Seager says he aims to build an ergonomic classic-snap experience. The excerpt suggests evaluating tool availability by checking which tools are strictly confined snaps, classic snaps, or unavailable as snaps. Today's Ubuntu Desktop will remain. ### Source excerpt Canonical has restarted work on Ubuntu Core Desktop, the immutable and attestable version of Ubuntu that the company says will over time become the default Ubuntu desktop. Jon Seager, Canonical's VP of engineering, laid out the plan and admitted that the 2023 developer preview "fell short" of what the company had in mind. On Core Desktop, everything ships as a snap, Canonical's sandboxed package format: the bootloader, the kernel, the desktop environment, background services and ...

During the Ubuntu 27.04 cycle, the new team plans to focus on browser-centric machines, developer workstations, and gaming machines, with daily images expected. The initial use cases reflect a key blocker: limited application availability in Snap form. Other challenges include modularizing the desktop, permission prompts, and supporting KDE Plasma alongside GNOME. Canonical says Ubuntu Desktop in its current form is not going away. ### Source excerpt Canonical engineers back in 2023 outlined plans for Ubuntu Core Desktop as their immutable Linux desktop. They made some good initial progress but since 2024 it went rather silent. Now they are reviving Ubuntu Core Desktop as their immutable desktop OS offering and with grand plans for the future... ## Running Ubuntu Snappy inside Docker DevFeed: [Running Ubuntu Snappy inside Docker]() Original publisher: [Read original article]() Author: andreacorbellini Published: 2015-03-25T20:46:00Z Content type: tutorial Language: en Sources: [Andrea Corbellini]() Topics: [Docker](), [Ubuntu](), [Package Management](), [mount](), [qemu]() Tags: [apparmor](), [container](), [docker](), [mount](), [qemu](), [snappy](), [ubuntu](), [ubuntu-core](), [xkcd]() ### AI overview A tutorial showing how to create and run an Ubuntu Core Docker image by downloading an Ubuntu Core image, accessing its filesystem with qemu-nbd, mounting the relevant partition, and creating a base Docker image. It also demonstrates installing and running a snappy package inside the container and discusses warnings related to AppArmor, DBus, and logind. ### Source excerpt Many of you may have already heard of Ubuntu Core. For those who haven't, it's a minimal Ubuntu version, running only a few essential services and ships with a new package manager (snappy) that provides transactional updates. Ubuntu Core provides a lightweight base operating system which is fast to deploy and easy to maintain up to date. It also uses a nice ... ## Running Ubuntu Snappy inside Docker DevFeed: [Running Ubuntu Snappy inside Docker]() Original publisher: [Read original article]() Author: andreacorbellini Published: 2015-03-25T20:46:00Z Content type: tutorial Language: en Sources: [Andrea Corbellini]() Topics: [Ubuntu](), [Docker]() Tags: [apparmor](), [docker](), [dockerfile](), [snappy](), [ubuntu](), [ubuntu-core](), [xkcd]() ### AI overview A tutorial explains how to create a Docker image from an Ubuntu Core image and run Snappy packages inside it. It demonstrates launching a web server and notes that services such as AppArmor, D-Bus, and logind are not started inside the container; virtualization may be appropriate when those services are needed. ### Source excerpt Many of you may have already heard of Ubuntu Core.
