Sunsetting Launchpad’s mailing lists
Published by jugmac00 May 22, 2025 in General
What are Launchpad’s mailing lists?
Launchpad’s mailing lists are team-based mailing lists, which means that each team can have one of them. E-mails from Launchpad’s mailing lists contain `lists.launchpad.net ` in their address.
For more information on the topic please see https://help.launchpad.net/ListHelp.
What are they not?
Please note that both lists.canonical.com and lists.ubuntu.com are not managed by Launchpad, but by Canonical Information Systems.
Timeline
Launchpad will no longer offer mailing lists as of the end of October 2025, which aligns with the end of the 25.10 cycle.
Migration paths
Depending on your use case, there are different alternatives available.
For a couple of years now, discourse has become a viable alternative for most scenarios. Launchpad also offers the Answers feature for discussions. If it is not so much about communication, but more about receiving information, e.g. for updates on a bug report, you should be aware that you can also subscribe teams to bugs.
Call for action
We are aware that your use case may be very different from the above listed ones. If you are using Launchpad’s mailing lists today and you do not see a clear way forward, please reach out to us to discuss your use case and how we can help you.
Please contact us on Matrix (#launchpad:ubuntu.com) or drop as a message via feedback@launchpad.net.
Please note that this is still work in progress, and we will provide more information over the upcoming weeks and months.
build_by_default=False for i386
Published by clinton-fung May 12, 2025 in General
More than 5 years ago, i386 was dropped as an architecture in Ubuntu. Despite this, i386 has remained selected by default as an architecture to build when creating new PPAs, snap recipes, or OCI recipes.
Today, we have disabled building for i386 by default. From now on, only amd64 will be selected by default when creating new PPAs, snap recipes, or OCI recipes. This change only affects newly created PPAs, snap recipes, or OCI recipes. Existing PPAs and recipes remain unchanged.
It’s worth noting that, although we have disabled building for i386 by default, it’s still possible to select i386 as a target architecture when creating new PPAs, snap recipes, or OCI recipes. In future, we may yet decide to disable this altogether but for now, the ability to target i386 remains.
Because targeting i386 is still possible (but requires intervention to enable), we don’t anticipate that this change will affect users, but if you are affected, please log a bug.
And as always, if you have any feedback, please let us know!
Make your first open source contribution

Launchpad and the Open Documentation Academy Live in Málaga
Launchpad is a web-based platform to support collaborative software development for open source projects. It offers a comprehensive suite of tools including bug tracking, code hosting , translation management, and package building
Launchpad is tightly integrated with the Ubuntu ecosystem, serving as a central hub for Ubuntu development and community contributions. Its features are designed to streamline the process of managing, developing, and distributing software in a collaborative environment.
Launchpad aims to foster strong community engagement by providing features that support collaboration, community management, and user participation, positioning itself as a central hub for open source communities.
Canonical’s Open Documentation Academy is a collaboration between Canonical’s documentation team and open source newcomers, experts, and those in-between, to help us all improve documentation, become better writers, and better open source contributors.
A key aim of the project is to set the standard for inclusive and welcoming collaboration while providing real value for both the contributors and the projects involved in the programme.
Join us at OpenSouthCode in Málaga
Launchpad and the Open Documentation Academy will join forces at OpenSouthCode 2025 in the wonderful city of Málaga, Spain, on June 20 – 21 2025.
The Open Documentation Academy will have a hands-on documentation workshop at the conference, where the participants will learn how to do meaningful open source contributions with the help of the Diátaxis documentation framework.
Launchpad’s Jürgen Gmach will be on-site and help you to land your first open source contribution.
Please register at https://www.opensouthcode.org/conferences/opensouthcode2025 – the conference and the workshop are free of charge. If you have any questions, please do not hesitate to reach out to us at feedback@launchpad.net.
Tenemos muchas ganas de conoceros. ¡Nos vemos en Málaga!
Celebrating community contributions
Published by clinton-fung April 25, 2025 in General
The Launchpad project is almost 21 years old! Many people have contributed to the project over this lifetime, and we are thankful for all of them. We understand the value of a strong community and we are taking steps to reinvigorate Launchpad’s once-thriving community.
There are two common suggestions for getting started in open source: fixing bugs and contributing to documentation. Early in 2024, Canonical launched the Canonical Open Documentation Academy; an initiative that aims to break down barriers to open source contribution, and work with the community to raise the bar for documentation practice. The Open Documentation Academy has been helping people get involved in open source and has also been helping projects achieve ever higher standards in documentation. Launchpad is one such project.
Today, we recognize and celebrate our community contributors. We hope they enjoyed contributing to Launchpad as much as we enjoyed working with them!

Introducing Launchpad Bug Templates
Published by alvarocs December 3, 2024 in General
The new feature bug templates in Launchpad aims to streamline the bug reporting process, making it more efficient for both users and project maintainers.
In the past, Launchpad provided only a basic description field for filling bug reports. This often led to incomplete or vague submissions, as users may not include essential details or steps to reproduce an issue. This could slow down the debugging process when fixing bugs.
To improve this, we are introducing bug templates. These allow project maintainers to guide users when reporting bugs. By offering a structured template, users are prompted to provide all the necessary information, which helps to speed up the development process.
To start using bug templates in your project, simply follow these steps:
- Access your project’s bug page view.
- Select ‘Configure bugs’.
- A field showing the bug template will prompt you to fill in your desired template.
- Save the changes. The template will now be available to users when they report a new bug for your project.
For now, only a default bug template can be set per project. Looking ahead, the idea is to expand this by introducing multiple bug templates per project, as well as templates for other content types such as merge proposals or answers. This will allow project maintainers to define various templates for different purposes, making the open-source collaboration process even more efficient.
Additionally, we will introduce Markdown support, allowing maintainers to create structured and visually clear templates using features such as headings, lists, or code blocks.
Launchpad’s new homepage

Launchpad’s new homepage
Launchpad has been around for a while, and its frontpage has remained untouched for a few years now.
If you go into launchpad.net, you’ll notice it looks quite different from what it has looked like for the past 10 years – it has been updated! The goal was to modernize it while trying to keep it looking like Launchpad. The contents have remained the same with only a few text additions, but there were a lot of styling changes.
The most relevant change is that the frontpage now uses Vanilla components (https://vanillaframework.io/docs). This alone, not only made the layout look more modern, but also made it better for a new curious user reaching the page from a mobile device. The accessibility score of the page – calculated with Google’s Lighthouse extension – increased from a 75 to an almost perfect 98!
Given the frontpage is so often the first impression users get when they want to check out Launchpad, we started there. But in the future, we envision the rest of Launchpad looking more modern and having a more intuitive UX.
As a final note, thank you to Peter Makowski for always giving a helping hand with frontend changes in Launchpad.
If you have any feedback for us, don’t forget to reach out in any of our channels. For feature requests you can reach us as feedback@launchpad.net or open a report in https://bugs.launchpad.net/launchpad.
To conclude this post, here is what Launchpad looked like in 2006, yesterday and today.
Launchpad in 2006
Launchpad-linked federated Matrix accounts
Published by ines-almeida January 22, 2024 in General
Users can now add their Matrix accounts to their profile in Launchpad, as requested by Canonical’s Community team.
We also took the chance to slightly rework the frontend and how we display social accounts in the user profiles. Instead of having different sections in the profile for each social account , all social accounts are now all under a “Social Accounts” section.
Adding a new matrix account to your profile works similarly to how it has always worked for other accounts. Under the “Social Accounts” section in your user profile, you should now see a “No matrix accounts registered” and an edit button that will lead you to the Matrix accounts edit page. To edit, remove or add new ones, you will see an edit button in front of your newly added accounts in your profile.
We also added new API endpoints Person.social_accounts and Person.getSocialAccountsByPlatform() that will list the social accounts for a user. For more information, see our API documentation.
Currently, only Matrix was added as a social platform. But during this process, we made it much easier for Launchpad developers to add new social platforms to Launchpad in the future.
Self-service riscv64 builds
Published by Colin Watson November 22, 2023 in PPA
Launchpad has supported building for riscv64 for a while, since it was a requirement to get Ubuntu’s riscv64 port going. We don’t actually have riscv64 hardware in our datacentre, since we’d need server-class hardware with the hypervisor extension and that’s still in its infancy; instead, we do full-system emulation of riscv64 on beefy amd64 hardware using qemu. This has worked well enough for a while, although it isn’t exactly fast.
The biggest problem with our setup wasn’t so much performance, though; it was that we were just using a bunch of manually-provisioned virtual machines, and they weren’t being reset to a clean state between builds. As a result, it would have been possible for a malicious build to compromise future builds on the same builder: it would only need a chroot or container escape. This violated our standard security model for builders, in which each build runs in an isolated ephemeral VM, and each VM is destroyed and restarted from a clean image at the end of every build. As a result, we had to limit the set of people who were allowed to have riscv64 builds on Launchpad, and we had to restrict things like snap recipes to only use very tightly-pinned parts from elsewhere on the internet (pinning is often a good idea anyway, but at an infrastructural level it isn’t something we need to require on other architectures).
We’ve wanted to bring this onto the same footing as our other architectures for some time. In Canonical’s most recent product development cycle, we worked with the OpenStack team to get riscv64 emulation support into nova, and installed a backport of this on our newest internal cloud region. This almost took care of the problem. However, Launchpad builder images start out as standard Ubuntu cloud images, which on riscv64 are only available from Ubuntu 22.04 LTS onwards; in testing 22.04-based VMs on other relatively slow architectures we already knew that we were seeing some mysterious hangs in snap recipe builds. Figuring this out blocked us for some time, and involved some pretty intensive debugging of the “strace absolutely everything in sight and see if anything sensible falls out” variety. We eventually narrowed this down to a LXD bug and were at least able to provide a workaround, at which point bringing up new builders was easy.
As a result, you can now enable riscv64 builds for yourself in your PPAs or snap recipes. Visit the PPA and follow the “Change details” link, or visit the snap recipe and follow the “Edit snap package” link; you’ll see a list of checkboxes under “Processors”, and you can enable or disable any that aren’t greyed out, including riscv64. This now means that all Ubuntu architectures are fully virtualized and unrestricted in Launchpad, making it easier for developers to experiment.
Introducing Project-Scoped Access Tokens
Published by ines-almeida November 20, 2023 in General
Access tokens can be used to access repositories on behalf of someone. They have scope limitations, optional expiry dates, and can be revoked at any time. They are a stricter and safer alternative to using real user authentication when needing to automate pushing and/or pulling from your git repositories.
This is a concept that has existed in Launchpad for a while now. If you have the right permissions in a git repository, you might have seen a “Manage Access Tokens” button in your repository’s page in the past.
These tokens can be extremely useful. But if you have multiple git repositories within a project, it can be a bit of a nuisance to create and manage access tokens for each repository.
So what’s new? We’ve now introduced project-scoped access tokens. These tokens reduce the trouble for the creation and maintenance of tokens for larger projects. A project access token will work as authentication for any git repository within that project.
Let’s say user A wants to run something in a remote server that requires pulling multiple git repositories from a project. User A can create a project access token, and restrict it to “repository pull” scope only. This token will then be valid authentication to pull from any repository within that project. And user A will be able to revoke that token once it’s no longer needed, keeping their real user authentication safe.
The same token will be invalid for pushing, or for accessing repositories within other projects. Also note that this is used for ‘authentication’, not ‘authorization’ – if the user doesn’t have access to a given git repository, their access token will not grant them permissions.
Anyone with permissions to edit a project will be able to create an access token, either through the UI or the API, using the same method as to create access tokens for git repositories. See Generating Access Tokens section in our documentation for instructions and other information.
This feature was implemented on request by our colleagues from the ROS team. We would love to get some feedback whether this also covers your use case. Please let us know.
New domain names for PPAs
Published by Colin Watson February 16, 2022 in PPA
Since they were introduced in 2007, Launchpad’s Personal Package Archives (PPAs) have always been hosted on ppa.launchpad.net. This has generally worked well, but one significant snag became clear later on: it was difficult to add HTTPS support for PPAs due to the way that cookies work on the web.
Launchpad uses a cookie for your login session, which is of course security-critical, and because we use multiple domain names for the main web application (bugs.launchpad.net, code.launchpad.net, and so on), the session cookie domain has to be set to allow subdomains of launchpad.net. We set the “Secure” flag on session cookies to ensure that browsers only ever send them over HTTPS, as well as the “HttpOnly” flag to prevent direct access to it from JavaScript; but there are still ways in which arbitrary JS on an HTTPS subdomain of launchpad.net might be able to exfiltrate or abuse users’ session cookies. As a result, we can never allow any HTTPS subdomain of launchpad.net to publish completely user-generated HTML that we don’t process first.
We don’t currently know of a way to get ppa.launchpad.net to serve arbitrary HTML as Content-Type: text/html, but this is quite a brittle protection as there are certainly ways (used for things like installer uploads) to upload arbitrary files to ppa.launchpad.net under a user-controlled directory structure, and we don’t want the webapp’s security to depend on nobody figuring out how to convince a browser to interpret any of that as arbitrary HTML. The librarian is already on a separate launchpadlibrarian.net domain name for a similar reason.
To resolve this dilemma, we’ve added a new ppa.launchpadcontent.net domain name which supports both HTTP and HTTPS (and similarly private-ppa.launchpadcontent.net for private PPAs, which as before is HTTPS-only). add-apt-repository in Ubuntu 22.04 will use the new domain name by default.
The old names will carry on working indefinitely – we know they’re embedded in lots of configuration and scripts, and we have no inclination to break all of those – but we recommend moving to the new names where possible. ppa.launchpad.net will remain HTTP-only.
Some systems may need to be updated to support the new domain name, particularly things like HTTP(S) proxy configuration files and no_proxy environment variables.
