After 3 weeks of the release date, Ubuntu finally opened the channel for upgrading from Ubuntu 25.04 to Ubuntu 25.10.
Ubuntu 25.10, code-name Questing Quokka, is the latest version that was released on October 9th. It features 9 month support until July 2026, Linux Kernel 6.17, GNOME Desktop 49, new Rust-based core utilities, new Ptyxis terminal emulator, and Loupe image viewer.
It as well removed the classic Xorg session and dropped “Startup Applications” tool. See Ubuntu 25.10 release note for more details.
Just one day ago, Ubuntu finally announced the upgrade channel for 25.04, while Ubuntu 24.04 may also upgrade to 25.04, then to 25.10.
We’re happy to announce that the upgrades to Ubuntu 25.10 (Questing Quokka) are now live!
This cycle also marks the arrival of amd64v3 as an architecture variant — shiny, fast, and ready for testing. If you haven’t already, I’d encourage reading the Discourse post for the full story:
https://discourse.ubuntu.com/t/introducing-architecture-variants-amd64v3-now-available-in-ubuntu-25-10/71312
Happy upgrading, and may your Quokka quest be bug-free!
Ubuntu 25.04 support will end in January 2026. If you decide to upgrade to Ubuntu 25.10, then it’s better to do following steps before getting started:
Ubuntu 25.04 now should automatically pop-up a dialog saying that Ubuntu 25.10 upgrade is available, with buttons to accept or refuse.
If you miss that dialog, then do following steps to manually start the upgrading process.
1. First launch Software & Updates, under “Updates” tab, make sure you set notify for any new Ubuntu version.
For Ubuntu server, edit /etc/update-manager/release-upgrades instead and set Prompt=normal
2. Next, launch Software Updater and install all the available updates. And, restart your computer if it asks.
For server with GUI, run the command below instead:
sudo apt update && sudo apt full-upgrade
3. Finally, either launch Software Updater again and click the “Upgrade” button.
Or, run the command below to start the upgrade process from terminal:
do-release-upgrade
then follow the wizard or terminal output to upgrade your Ubuntu.
NOTE: Don’t go far away from your computer. It will ask few questions during the upgrade process, e.g., whether to keep obsolete packages or not. And, when everything’s done well, it will ask you restart computer to complete.

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.
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.
Ubuntu 25.10's Rust-based coreutils had a bug preventing automatic updates from working. Here's what happened, why it matters, and how it was resolved.

Canonical has released Ubuntu 25.10 “Questing Quokka,” an interim release that introduces a foundational shift toward memory-safe utilities while delivering the latest desktop environment and significant AI-powered application updates. Supported for nine months, this version’s most impactful change is the default implementation of sudo and coreutils rewritten in Rust, a strategic move to improve system-wide […]
The post Ubuntu 25.10: A Major Release Comes with a Rust Core, AI Apps, and GNOME 49 appeared first on UbuntuPIT.
Ubuntu 25.10, code-name Questing Quokka was released! Here are some top things to do, after installed the new Ubuntu desktop release, to make it ready to use.
It’s been many years, GNOME still does NOT have a graphical option out-of-box to create new documents in file manager. Though, it’s easy to enable this feature by putting a file into user’s Template folder.
To do so, launch Text Editor and create a new empty document. Then, press Ctrl+Shift+S to open save file dialog. Finally, choose save it to Home -> Templates with whatever file-name you want to display as ‘New Document’ sub-menu option.
The default “Printer” page in Settings is OK for basic use.
If you have a printer physically connected to the Ubuntu computer, then you may open terminal (Ctrl+Alt+T) and run command to install the graphical CUPS configuration tool:
sudo apt install system-config-printer
Tips: run sudo apt update to refresh cache if it says “Unable to locate package”.
Then, search & launch Printers app to get more controls, such as share printer, remote admin, policies, and default print options.
The left panel, aka Ubuntu Dock, is handled by an extension forked from dash-to-dock.
By going to Settings -> Ubuntu Desktop -> Dock, you may configure the left panel/dock with basic options, such as its position, icon size, auto-hide, shorten panel, show on primary or all displays, hide trash and volumes.
For more, install extension manager either by running the command below in terminal (Ctrl+Alt+T) or by using App Center (filter by Debian package):
sudo apt install gnome-shell-extension-manager
Then you may launch extension manager, and open preferences dialog for the Ubuntu Dock extension, which includes many more configure options for the left panel/dock:
If you chose the “Default Selection” option while installing Ubuntu 25.10, then you’ll see that many default applications are NOT pre-installed!
To install them back, simply launch App Center, then search and install the apps below one by one (mostly filtered by Debian package).
Or, open terminal (Ctrl+Alt+T) and run commands below instead (run sudo apt update to refresh cache first).
sudo apt install libreoffice
sudo apt install file-roller
sudo apt install shotwell
sudo apt install deja-dup
sudo apt install gnome-snapshot
sudo apt install showtime
sudo apt install rhythmbox
sudo apt install remmina
sudo apt install transmission
Due to legal reason, Ubuntu does not include some media codec for video/audio playback, Microsoft TTF fonts, and RAR archive supports.
To get them, press Ctrl+Alt+T to open up a terminal window, and run command:
sudo apt install ubuntu-restricted-extras
While downloading & installing the MS fonts, it will prompt to accept licence, use Tab key to highlight OK and hit Enter.
Flatpak is a popular package format runs in sandbox environment. Tons of applications support Linux through Flatpak package.
To enable Flatpak support in Ubuntu, simply open terminal (Ctrl+Alt+T) and run command:
sudo apt install flatpak
Next, you may install local flatpak files by running command:
flatpak install drag-and-drop-flatpak-file-here
Or, add the Flathub repository into system:
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
For choice, add --user flag for current user only. Then, use the command in a Flathub app page to install (click down arrow besides “Install” button).
Due to this bug, flatpak install may refuse to work. Try running it with sudo at beginning until it’s fixed.
NOTE: After enabled Flatpak support, you need a log out and back in to apply variable changes.
AppImage is another popular way to run applications in Linux. It’s a portable, non-install package format, that can be run directly (after added executable permission) to launch application.
Since Ubuntu 22.04, user needs to press Ctrl+Alt+T to open terminal, and run command to install the required library for AppImage support:
sudo apt install libfuse2
Besides the default Settings (aka Gnome Control Center), they are few other graphical tools to help configure your Ubuntu desktop.
GNOME Tweaks is the popular alternative to Gnome Control Center (aka Settings), which offers graphics options to configure:
The app is available to install either from App Center (filter by Debian package) or by running command below in terminal:
sudo apt install gnome-tweaks
Extension Manager is one of the must-have applications to install & manage extensions in GNOME desktop. It can be installed by running the command below in terminal:
sudo apt install gnome-shell-extension-manager
For dual-boot or multi-boot computers, and users who want to configure the boot menu, Grub-customizer is good choice to make things simple.
To install the app, open terminal and run commands below one by one to get from developer’s PPA:
sudo add-apt-repository ppa:danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer
NOTE: The PPA does NOT support Ubuntu 25.10 at the moment of writing, check the PPA page for details.
If you want to change the login screen background, then GDM settings is a good choice that also supports configuring fonts, top-bar, colors, etc for the login screen.
NOTE: GDM Settings has the potential to break your login screen. Use it at your own risk!
To install the app in Ubuntu 25.10, run the commands below one by one to get from PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/gdm-settings sudo apt update sudo apt install gdm-settings
For advanced users, there’s also “Dconf Editor” that offers even more hidden configuration options.
To install the tool, run command:
sudo apt install dconf-editor
If you want to hide or tweak the top-panel (e.g., size and position) and panel items (e.g., clock option), configure the desktop behaviors and animations, then Just Perfection extension provides many options that can do the job.
Simply, search and install the extension using “Extension Manager” app, then you can go back “Installed” tab and click open the Just Perfection setting page for the configuration options.
For NVIDIA graphics card, you may launch Additional drivers and select install the latest NVIDIA 580 driver for better gaming performance.
If you prefer launching applications by using desktop shortcuts, then install Extension Manager that’s mentioned above, and use it to search & install “Add to Desktop” extension.
After that, you may right-click on your favorite apps in either app grid or GNOME Overview search result to add them into desktop.
There are even more things you can do to make Ubuntu desktop better for use. The things however differ depend on users. Please leave comment below, if you have any other good advice to tweak the Ubuntu Desktop.
Ubuntu 25.10, code-name Questing Quokka, was officially released today!
This is a new short term release with 9 months support until July 2026. New features include the latest Linux Kernel 6.17, GNOME Desktop 49, and more.
Thanks to Kernel 6.17, the new release features Attack Vector Controls, making easy to manage CPU vulnerability mitigations. It also added AMD SmartMux support for hybrid laptops, nested virtualization on Arm, and better support for AMD processors with mix of classic and dense cores.
Other Kernel changes include Raspberry Pi RP1 PCI device support, touch Bars support on x86 MacBook Pros, new drivers for Lenovo Legion Go S gaming handheld, and more. See more in kernelnewbies.
For Ubuntu Desktop, the installer improved TPM-Backed encryption with passphrase support and regeneration of the recovery key. And, Software Updater window will no longer pop up unprompted. Instead, it shows an icon in system tray, reminding that updates are available.

Due to upstream (meaning GNOME 49), “Ubuntu on Xorg” session is no longer available, though the GDM login screen still supports loading other Xorg desktop sessions, e.g., XFCE, MATE, and Cinnamon.
Ubuntu 25.10 introduced 2 new default apps. It replaced Gnome Terminal with new default Ptyxis container-focused terminal emulator, and replaced Eye of Gnome (EOG) with touch-friendly Loupe image viewer which is written in Rust and powered by the Glycin library, which also handles the desktop wallpaper.

Thanks to Gnome 49, it also added support changing the display brightness in the Quick Settings when HDR is enabled. And, these new HDR brightness controls support external displays, and allow multiple displays to be adjusted at the same time.

Other desktop changes include:
Besides new Kernel and Gnome 49, Ubuntu 25.10 now uses sudo-rs as the default sudo provider. It is a memory safe implementation of sudo and su, written in Rust. For end user, there’s no visual difference as it works just like before.
In addition, the release now use Rust based core utilities. This change however may cause potential issues. In my case, it caused issue (fixed now) discovering other multi-boot operating systems on my computer.
As well, there are updated toolchains, including GCC 15.2, binutils 2.45, glic 2.42, Python 3.13.7 (Python 3.14 also available), LLVM 20 (21 is available), Ruest 1.85 (1.88 is also available), Golang 1.24, OpenJDK 21 (25 and 26 EA are also available), Zig 0.14.1, and .NET 10 preview.
For more about Ubuntu 25.10, see the official announcement and release note.
The official images for desktop, server, and WSL are available to download in Ubuntu website via the link below:
For choice, you may get Ubuntu 25.10 from this page, or choose a download mirror that near to you.
For Ubuntu 25.04 users, the upgrade channel is not ready at the moment of writing. Try installing all updates via Software Updater utility, then run update-manager -c to check if upgrade is available.
If you see the "unable to capture a screenshot, all possible methods failed" error when using GNOME Screenshot in Ubuntu, it is not a bug – but by design.
