What makes a craft

Daniel W. Steinbrook sheds “some light on the philosophy across the growing list of Canonical packaging tools, including Snapcraft, Charmcraft, and Rockcraft”. Daniel informs us that knowing this will give a “better experience for package maintainers”, and may benefit anyone needing to debug their own ‘builds’. We’re told the craft principles, the standardized and modular approach, and more.

Upcoming autopkgtest migration announcement

Ural Tunaboyu reminds us of the new autopkgtest instance which should mean more reliable testbeds. We’re told with Ubuntu 26.04 LTS now released Ubuntu 26.10 (Stonking Stingray) should be “fairly seamless” for autopkgtest users. We’re told of what is being done in the coming weeks, and details we should know if we’re users of autopkgtest. Dates and more will be provided via replies on this thread.

An update on rust-coreutils

Ravi Kant Sharma provides a follow up to two prior posts by different authors on Ubuntu using rust-coreutils. We’re told what has happened after the prior announcement in the spirit of transparency. We’re told of the creation of an internal team who started a review and noted some ‘serious concerns’ leading to the commission of an independent external security audit. We’re told of this audit, performed by Zellic, and told the “vast majority of issues have been addressed and resolved” by upstream developers. The current status of Ubuntu 26.04 LTS is covered in regards to rust-coreutil’s packages, given a conclusion where Sylvestre Ledru and the uutils community are thanked, along with Zellic, and many others in the open source community. A list of CVE disclosures is provided, and we are told the migration was a success.

Hello old new “Projects” directory!

Matthias Klumpp (Ximion) tells us that if we’ve installed a recent Desktop Linux we may have noticed a new folder titled “Projects”. This blog tells us why it’s there, and reminds us of it’s history (existed since 2007 with 11 year old feature request). We’re also told how we can control the behavior on our own system, should we decide we don’t like it and want it gone for example, or wish to add other things too. Mention is also made of some other features we’ll find in xdg-user-dirs 0.20 release.

From Jammy to Resolute: how Ubuntu’s toolchains have evolved

In this blog, Samir Kamerkar covers some of the tools found in Ubuntu’s toolchains that “collapse half a day of setup into a single command or two”. This blog discusses the many changes in toolchains since Ubuntu 22.04 LTS, Ubuntu 24.04 LTS through to the current Ubuntu 26.04 LTS. This is a long and somewhat detailed post covering LTS releases only, with links for those wanting more on specific tools. The focus is somewhat on the latest Ubuntu 26.04 and how it’s a great platform for developers. The blog ends with a preview of the future too.

Meet the Members: Heather Ellsworth

“I am currently the senior developer relations engineer at Mozilla Thunderbird and I’ve been a long time Linux user, starting with Ubuntu 7.04. I remember being in grad school using that early version of Ubuntu and daydreaming of what it might be like to work on Ubuntu and then I got that very opportunity when I was on the Ubuntu desktop team at Canonical for 4 years, before moving onto Thunderbird. I continue to love open source and advocate for its adoption anytime I can.” -Heather Ellsworth
