Besides the early fallout of switching to Rust Coreutils on Ubuntu 25.10 causing some breakage, a more pressing issue has been discovered: Ubuntu 25.10’s unattended upgrades functionality for automatic security updates is currently broken due to a Rust Coreutils bug.
Earlier this month it was reported that the date -r command can report the wrong date on Ubuntu 25.10 due to a Rust Coreutils difference compared to GNU Coreutils. It was noted that this could cause issues for backup scripts and other software relying on the “date -r” output and behavior being the same as GNU Coreutils
date -r reports current date instead of date specified by reference file
Seems like it was not simply a “difference compared to GNU coreutils” — it was just giving completely the wrong date.
That’s why its in 25.10 before LTS release. To test “early” in real world environments and find these issues. But from the Rust UUtils project side, I wonder how they did not catch this, if its producing different output.
Flatpak support broken, shovelware pile Snap Store pushed down users’ throats, and now this.
Anyone who thinks that Ubuntu is the best choice for new Linux users is fundamentally wrong.
