Rust on Ubuntu shares updates about how we are using the Rust 
programming language on Ubuntu. This update is for updates and news that happened during July 2026. Admin note: this month’s update is being published early due to the Canonical mid-year break.
The Rust Foundation is strengthening Rust Infrastructure Security with Ubuntu Pro.
Canonical is providing GitHub Actions self-hosted runners to the Rust Project in cooperation with the Rust Infrastructure Team for the s390x architecture. GitHub-hosted runners only have amd64 and arm64 machines. This will enable better support for the s390x-unknown-linux-gnu target. Other machine architectures will be added in the future.
