As predicted, the “Re-written in Rust” versions of the GNU Core Utils (known as “uutils”) have been causing problems on the recently shipped Ubuntu 25.10. In this case, the Rust-developed clone of the “date” command had significant issues that caused automatic system update checks on Ubuntu to fail to occur. Worth noting that the Rust-based “date” clone only passes 2 of the 8 test cases for the utility — that’s a 75% failure rate. And some other Rust-based Core Utils clones fare even worse. The Ubuntu team knew the Rust “uutil” failure rate was this extreme when they chose to replace the well tested GNU Core Utils. Fortunately, this specific issue has been fixed and made available to Ubuntu users. Unfortunately… Considering the extremely large number of known test failures of the Rust “uutils” — and the fact that those existing tests only cover a tiny fraction of the total functionality of the GNU Core Utils which these Rust versions are meant to replace (meaning most missing functionality and errors will not be caught by the tests) — it seems like a reasonable bet that this is only the beginning of the issues which Ubuntu will see in the coming months.
