Some template builds are failing when they install packages with apt. Ubuntu's package servers (https://status.canonical.com/) are currently unreachable, so build steps that run apt-get update or apt-get install may fail.

Running sandboxes and sandbox creation are not affected.

If your build fails on an apt step, please retry it or wait once the upstream issue is resolved. Templates that don't install Ubuntu packages are expected to build normally.

We're monitoring the issue and will post an update when builds are back to normal.
