Hello! I have a snap-installed Maas 3.7.2 environment in which Ubuntu 24.04 deployments fail starting approximately Thursday May 12, 2026 at 5pm EDT. I also have another snap-installed MaaS 3.7.2 environment in which Ubuntu 24.04 deployments continue to correctly function. I’m rather at a loss as to the differences between these two environments, and what I need to change in the problematic environment so as to allow deployments of Ubuntu 24.04 to succeed. Based on the lack of questions I’ve seen regarding this type of error, I’m of the mindset that the issue is rather local to my environment in which it’s occurring and not a more widespread issue.
In the failing environment, I can see the from the logs that curtin successfully updates the repository metadata and then downloads linux-generic and its dependencies:
Running command ['unshare', '--fork', '--pid', '--', 'chroot', '/tmp/tmpikc6zv7n/target', 'apt-get', '--quiet', '--option=Acquire::Languages=none', '--option=Dir::Etc::sourcelist=/tmp/tmpizvkblnq/sources.list', '--option=Dir::Etc::sourceparts=/tmp/tmpizvkblnq/sources.list.d', 'update'] with allowed return codes [0] (capture=False)

The only difference I can find in these environments is the version of curtin being used.
Version of curtin from the environment in which Ubuntu 24.04 deploys succeed:
curtin: Installation started. (23.1.1-1118-g3977ce90-0ubuntu1~ubuntu24.04.1)
Version of curtin from the environment in which Ubuntu 24.04 deploys fail:
curtin: Installation started. (23.1.1-1124-g7324b43b-0ubuntu1~ubuntu24.04.1)
I’ve tried removing and re-adding the 24.04 boot source with the thought that perhaps the environment is using a corrupted version of the image, but based on the speed with which the image is synced after re-adding the 24.04 boot source I am doubtful that removing the source actually removes the image from the controller.
This issue is having quite the impact on my team’s use of our MaaS environment, and it has me very puzzled. Any thoughts, suggestions, or advice would be greatly appreciated, and thank you in advance for your time.
