Ubuntu 26.10 completes the distro’s move to Rust-based core utilities, with the commands previously held back due to security issues now migrated to memory-safe versions. cp ,  mv  and  rm  were held back on their GNU versions in Ubuntu 26.04 LTS due to a crop of TOCTOU (time-of-check to time-of-use) issues that needed to be fixed in the  uutils  versions.  With those issues resolved upstream, Ubuntu 26.10 finishes the job.

Canonical donates €40k a year to help fund work on Rust software Canonical’s engineers began ‘oxidising’ the distro – replacing foundational software with Rust alternatives – in 2025.
