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
datecommand, 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.
I have to start by giving you a simple intro.
I am 78 years old, ex military with 4 grown children, and 1 ex wife.
I decided to investigate Ubuntu about 6 years ago. There were 3 reasons for that. I had had enough of Windows experiences going back to moving away from the Commodre 64.
I used Apple for many many years but their system was not only very expensive but memory hungry and I need to keep things simple and reliable.
The 3rd reason I came to Ubuntu was that Linux was FREE.
I have no mathematical or computer skills. Its a case of monkey see, monkey do, so I launched myself into Ubuntu but stumbled when I could not update it. Back then I obviously didnt read enough to smooth the process, so I stayed with my Apple Mac until frustration forced me back to Linux.
I now run 2 small Dell computers, 1 has Ubuntu 25.10, which you have just helped fix the software on, and the other Dell runs an app called Home Assistant.
Home Assistant is used for me to explore home automation. That is a big wide wonderful world and keeps me on my toes.
The reason I am writing is to tell you that you, like so many other people who write the above articles and dont get the kudos you deserve. There are probably dozens, if not thousands of people like me, who scratch around, mostly in the dark, unable to remember Linux commands, who rely on people like you to keep our systems running.
I am no wiser to Ubuntu or computer languages than previously but I am more confident in looking for answers to questions often found in the command like which will tell me that something is not working properly.
I am going to attempt to buy you a coffee. See how thick I am, I even struggle with that.
So thank you for your dedication and devotion to the computer language.
