For users of Ubuntu 25.10 Questing Quokka, Ubuntu team announced how to fix the issue that automatically check of updates not working in desktop, server, cloud, and container.

As you may know, Ubuntu replaced GNU Core Utilities with Rust in 25.10. Most core command line tools, such as chroot, dd, du, echo, ls, mkdir, pwd, sudo, who, and more, are now the “memory safe” Rust-based utilities, though for end users, they can be used just like before.

Ubuntu 25.10 switched to Rust based core-utils

This Rust rewritten coreutils so far has many issues that break things in Ubuntu 25.10. And, Ubuntu and upstream developer team keep working to fix them.

As far as I know, Grub bootloader did not (fixed now) find and load dual- or multi-boot operating systems, who command does not show who is logged in, stty command seems to return invalid or non-standard argument format that breaks interactive terminal applications.

Ubuntu by default checks and installs security updates automatically, which is useful to keep your system (especially for public server) safe.

Ubuntu by default automatically check & install security updates

However, due to bug in date command, some Ubuntu 25.10 systems may be unable to automatically check for available. It’s announced few days ago:

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.

As mentioned in the announcement, the issue may affect users who have rust-coreutils <=0.2.2-0ubuntu2. And, it can be easily fixed by installing/updating to rust-coreutils 0.2.2-0ubuntu2.1 or later.

• For Ubuntu Desktop, simply launch “Software Updater“, then install all the available updates.
• If you’re OK with Linux commands, then run the command below to refresh cache and update the package:

  sudo apt install --update rust-coreutils

  

If you found other issues about core utils, then you may either report to this Ubuntu page or the upstream Github page.

And, this discourse thread provides the choice to revert back the old GNU based core-utils for those who need it.

BleachBit, the CCleaner alternative system cleaner app, released new 5.0.2 in last week with support for cleaning more app caches.

BleachBit is a free open-source application for Linux and Windows that can free up disk space by deleting cookies, cleaning internet history, discarding junks and removing logs.

It support cleaning thousands of applications, such as Firefox, Chrome/Chromium, Opera, and more, removing apt, bash, and system caches, shredding files to prevent recovery, wiping free disk space, and vacuuming Firefox to improve speed without removing any data.

The last major 5.0.0 version, which was released in May, added cleaning more apps support, including Librewolf and Microsoft Edge for Linux, beta and snap versions of Discard.

In the new 5.0.2 version, it now supports cleaning caches for pacman, the default package manager for Arch and Manjaro etc Linux Distributions.

For Ubuntu and other Linux have apps installed as snap packages, the release also added support removing snap packages that have been disabled. It will trigger native snap remove command running silently in background to remove all disabled snaps, though it was not working good in my case as it stuck at Sl sleeping status waiting for something.

Besides that, the new version also updated its UI. Like web browser, it now supports Ctrl+Scroll or Ctrl + +/- keyboard shortcuts to change text font size, and F11 to toggle full-screen mode.

Other changes are mostly bug-fixes and translation updates. They include:

• Fix Firefox vacuuming error for version 140 and later.
• Improve KDE stability by skipping KDE files when leaning system cache.
• Improve compatibility in headless and restricted environments such as crontab.
• Add description for Exaile music player, and update description for Audacious.
• Add new Gaeilge and සිංහල translations, and update 68 languages.
• Add packages for AlmaLinux, Debian 13, Linux Mint Zara, and openSUSE Leap 15.6 and 16.0.

In addition, the release uses a newly renewed digital certificate that may cause temporary security warnings from antivirus software in Windows. For more, see the official release note.
