Ubuntu 25.10 Unattended Upgrades Broken Due To Rust Coreutils Bug (www.phoronix.com)

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" โ€” it was just giving completely the wrong date.
