According to a statement released by Canonical, a flaw has been discovered in the Rust-based version of uutils bundled with Ubuntu 25.10. The bug prevents the system from automatically applying available software updates, affecting cloud deployments, container images, as well as desktop and server editions of Ubuntu.
To determine whether a system is impacted, users can run the command dpkg -l rust-coreutils to check the package version. Systems running version 0.2.2-0ubuntu2.1 or later are unaffected, while earlier versions remain vulnerable to this issue.
To resolve the problem, users may manually trigger updates via the apt command or other utility mirrors, such as by executing sudo apt install --update rust-coreutils. Once the component is updated, the system will resume its ability to automatically check for and apply updates.
This Rust-based component is part of Ubuntu’s broader initiative to “oxidize” the distribution—an effort introduced with version 25.10 that replaces traditional GNU utilities with uutils and sudo-rs. The goal is to evaluate whether these Rust-implemented tools can meet the stability and performance standards required for Ubuntu’s upcoming Long-Term Support (LTS) release scheduled for April 2026.
