We’re seeing intermittent template build failures caused by an upstream outage. Any build or sandbox command that installs packages via `apt` may intermittently fail or time out. Retries may succeed. Upstream status: [**https://status.canonical.com/**](https://status.canonical.com/#/) We’re monitoring and will update as it recovers.
