Canonical is reporting an outage of Ubuntu's package archives, and our team has confirmed some workloads are unable to reach them. We'll continue to monitor availability and update this incident if the situation improves.

Workloads running on GitHub Actions are automatically rerouted to different mirrors.

Some Docker builds using Ubuntu base images are seeing degraded performance and errors.

A temporary workaround can be added to your Dockerfile until registries recover:

Ubuntu 22.04 and earlier:

RUN sed -i 's%http://\(archive\|security\).ubuntu.com/%http://azure.archive.ubuntu.com/%g' /etc/apt/sources.list

Ubuntu 24.04 and later:

RUN sed -i 's%http://\(archive\|security\).ubuntu.com/%http://azure.archive.ubuntu.com/%g' /etc/apt/sources.list.d/ubuntu.sources

We recommend undoing these changes once registries recover to remain aligned with base images.
