The Ubuntu 25.10 transition to using some Rust system utilities continues proving quite rocky. Beyond some early performance issues with Rust Coreutils, breakage for some executables, and broken unattended upgrades due to a Rust Coreutils bug, it’s also sudo-rs now causing Ubuntu developers some headaches. There are two moderate security issues affecting sudo-rs, the Rust version of sudo being used by Ubuntu 25.10.
The price of being on the bleeding edge.
But also, trust the process, it’s a feature not a bug.
ALL software has bugs. Doesn’t matter what the language is.
