Call for testing: snaps in Trusty

There is a huge announcement coming: snaps now run in Ubuntu 14.04 Trusty Tahr.

Take a moment to note how big this is. Ubuntu 14.04 is a long-term release that will be supported until 2019. Ubuntu 16.04 is also a long-term release that will be supported until 2021. We have many many many users in both releases, some of which will stay there until we drop the support. Before this snappy new world, all those users were stuck with the versions of all their programs released in 2014 or 2016, getting only updates for security and critical issues. Just try to remember how your favorite program looked 5 years ago; maybe it didn't even exist. We were used to choose between stability and cool new features.

Well, a new world is possible. With snaps you can have a stable base system with frequent updates for every program, without the risk of breaking your machine. And now if you are a Trusty user, you can just start taking advantage of all this. If you are a developer, you have to prepare only one release and it will just work in all the supported Ubuntu releases.

Awesome, right? The Ubuntu devs have been doing a great job. snapd has already landed in the Trusty archive, and we have been running many manual and automated tests on it. So we would like now to invite the community to test it, explore weird paths, try to break it. We will appreciate it very much, but all of those Trusty users out there will love it, when they receive loads of new high quality free software on their oldie machines.

So, how to get started?

If you are already running Trusty, you will just have to install snapd:

$ sudo apt update && sudo apt install snapd

Reboot your system after that in case you had a kernel update pending, and to get the paths for the new snap binaries set up.

If you are running a different Ubuntu release, you can Install Ubuntu in a virtual machine. Just make sure that you install the

Once you have Trusty with snapd ready, try a few commands:

$ snap list
$ sudo snap install hello-world
$ hello-world
$ snap find something

Keep searching for snaps until you find one that's interesting. Install it, try it, and let us know how it goes.

If you find something wrong, please report a bug with the trusty tag. If you are new to the Ubuntu community or get lost on the way, come and join us in Rocket Chat.

And after a good session of testing, sit down, relax, and get ohmygiraffe. With love from popey:

$ sudo snap install ohmygiraffe
$ ohmygiraffe

Ubuntu Testing Day wrap up - Ubuntu Core and QEMU (20170203)

After a little break, on the first Friday of February we resumed the Ubuntu Testing Days.

This session was pretty interesting, because after setting some of the bases last year we are now ready to dig deep into the most important projects that will define the future of Ubuntu.

We talked about Ubuntu Core, a snap package that is the base of the operating system. Because it is a snap, it gets the same benefits as all the other snaps: automatic updates, rollbacks in case of error during installation, read-only mount of the code, isolation from other snaps, multiple channels on the store for different levels of stability, etc.

The features, philosophy and future of Core were presented by Michael Vogt and Zygmunt Krynicki, and then Federico Giménez did a great demo of how to create an image and test it in QEMU.

There are plenty of resources in the Ubuntu websites related to Ubuntu Core.

To get started, we recommend to follow this guide to run the operating system in a virtual machine.

After that, and if you are feeling brave and want to help Michael, Zygmund and Federico, you can download the candidate image instead, from This is the image that's being currently tested, so if you find something wrong or weird, please report a bug in Launchpad.

Finally, if you want to learn more about the snaps that compose the image and take a peek at the things that we'll cover in the following testing days, you can follow the tutorial to create your own Core image.

On this session we were also accompanied by Robert Wolff who works on 96boards at Linaro. He has an awesome show every Thursday called Open Hours. At 96boards they are building open Linux boards for prototyping and embedded computing. Anybody can jump into the Open Hours to learn more about this cool work.

The great news that Robert brought is that both Open Hours and Ubuntu Testing Days will be focused on Ubuntu Core this month. He will be our guest again next Friday, February 10th, where he will be talking about the DragonBoard 410c. Also my good friend Oliver Grawert will be with us, and he will talk about the work he has been doing to enable Ubuntu in this board.

Great topics ahead, and a full new world of possiblities now that we are mixing free software with open hardware and affordable prototyping tools. Remember, every Friday in, no se lo pierda.

Call for testing: IPFS

Happy new year Ubunteros and Ubunteras!

If you have been following our testing days, you will know by now that our intention is to get more people contributing to Ubuntu and free software projects, and to help them getting started through testing and related tasks. So, we will be making frequent calls for testing where you can contribute and learn. Educational AND fun ^_^

To start the year, I would like to invite you to test the IPFS candidate snap. IPFS is a really interesting free project for distributed storage. You can read more about it and watch a demo in the IPFS website.

We have pushed a nice snap with their latest stable version to the candidate channel in the store. But before we publish it to the stable channel we would like to get more people testing it.

You can get a clean and safe environment to test following some of the guides you'll find on the summaries of the past testing days.

Or, if you want to use your current system, you can just do:

$ sudo snap install ipfs --candidate

I have written a gist with a simple guide to get started testing it

If you finish that successfully and still have more time, or are curious about ipfs, please continue with an exploratory testing session. The idea here is just to execute random commands, try unusual inputs and just play around.

You can get ideas from the IPFS docs.

When you are done, please send me an email with your results and any comments. And if you get stuck or have any kind of question, please don't hesitate to ask. Remember that we welcome everybody.

Instaladores de Firma Digital de Costa Rica para GNU/Linux

Este proyecto de instaladores se ha creado en conjunto con Luis Zárate para facilitar la instalación de las herramientas necesarias de Firma Digital de Costa Rica en distribuciones GNU/Linux. Se trata de un desarrollo no oficial, creado voluntariamente para mejorar el soporte en diversas distribuciones este sistema operativo, inicialmente para Debian y Ubuntu y próximamente para Fedora, CentOS, openSUSE y Arch.

El mecanismo para instalar los instaladores se realiza mediante un repositorio. Esto permite facilitar la instalación de los paquetes y poder recibir actualizaciones de los mismos de la misma manera que el resto de software del sistema.

Los instaladores configuran el sistema para agregar confianza a los certificados de la jerarquía nacional en los diferentes programas que hacen uso de almacenes de certificados (NSS de Mozilla, OpenSSL, GnuTLS y Java), así como el controlador del lector de tarjetas y también el módulo para poder manejar la tarjeta de Firma Digital.

Basados en parte en las guías previas con diversas mejoras, se ha verificado que tras la instalación del paquete se pueden utilizar servicios de Firma Digital y se listan las autoridades de certificados de la jerarquía nacional en software como Mozilla Firefox, Mozilla Thunderbird, Chromium/Chrome, Evolution, Seahorse (contraseñas y claves) y aplicaciones Java.

Las instrucciones de instalación están disponibles en el sitio web
