Due to a now-resolved bug in the date command, some Ubuntu 25.10 systems have been unable to automatically check for available software updates. Affected machines include cloud deployments, container images, Ubuntu Desktop and Ubuntu Server installs.
To check if your system is affected, run dpkg -l rust-coreutils and check the version field: Systems with version 0.2.2-0ubuntu2.1 or later are not affected.
If your system is using rust-coreutils <= 0.2.2-0ubuntu2, you can remediate the issue by manually updating the rust-coreutils package:
sudo apt install --update rust-coreutils
If you have been manually updating your system using apt or otherwise, you are likely unaffected by this issue.
