#ubuntu2604 — Public Fediverse posts

I had a weird bug in the Display manager in Ubuntu 26.04 (Gnome with Wayland). I couldn't save changes to my monitor settings -- resolution, arrangement, etc.

Here's the solution:

rm .config/monitors.xml

log out and log back in again

Sachez le, pour retrouver l'application Logiciels et mises à jour et donc l'onglet Pilotes additionnels (aka propriétaires) dans #Ubuntu2604, il faut installer le paquet :

Iată o postare optimizată pentru Mastodon despre noul stack HWE de virtualizare pentru Ubuntu 26.04 LTS, direct în limba română și fără menționarea vreunei surse:

🖥️ Ubuntu 26.04 LTS primește un stack opțional HWE pentru virtualizare!

Canonical extinde conceptul de Hardware Enablement (HWE) – folosit până acum în special pentru kernel – și către tehnologiile de virtualizare. Administratorii de sistem pot acum accesa cele mai noi versiuni ale pachetelor de virtualizare direct pe sistemele Ubuntu 26.04 LTS, fără a renunța la stabilitatea oferită de o versiune cu suport pe termen lung.

✨ Principalele detalii despre HWE-ul de virtualizare:

📦 Componente modernizate în mod continuu:
• Include pachetele dedicate qemu-hwe, libvirt-hwe, edk2-hwe (firmware OVMF) și seabios-hwe.
• Aceste pachete vor primi actualizări dinamic la fiecare 6 luni, preluând versiunile din lansările interimare Ubuntu.

🔐 Sincronizare cu tehnologiile moderne de Confidențialitate (AMD SEV-SNP & Intel TDX):
• Facilitează adoptarea rapidă a noilor funcționalități hardware pentru Confidential Computing, AI confidențial și izolare avansată a mașinilor virtuale.

⚙️ Complet opțional și sigur:
• Instalările standard vor păstra versiunile implicite de virtualizare. Activarea se face la alegerea administratorului.
• Canonical oferă instrumentul ubuntu_virt_helper pentru a gestiona întregul stack ca un ansamblu unificat, prevenind neconcordanțele de versiuni între QEMU, libvirt și firmware.

🚀 Soluția ideală pentru centre de date și Cloud:
• Elimină dilema de a alege între o versiune interimară cu pachete noi și o versiune LTS stabilă – oferind acum ce este mai bun din ambele lumi.

O evoluție excelentă pentru infrastructura enterprise pe Linux! 🚀

Installing .NET 10.0 on Ubuntu proot-distro with Termux on Android

.NET 10.0 is a new version of the modern .NET framework that brings several improvements across different areas of the software development kit, including runtime improvements (JIT inlining improvements, method devirtualization, and so on), new APIs in .NET libraries (new JSON deserialization options, post-quantum cryptography support, and so on), and many more improvements.

Normally, any .NET applications that are built for a specific platform can be run normally, such as Android applications made with MAUI. However, what if you’ve planned to run a CLI .NET application on Android? Or an application for computers? Termux can provide you with a solution.

Recent improvements to Termux involved changing how proot-distro downloads the distribution containers so that it utilizes Docker Hub to download the necessary assets and configure them to be usable. Follow the below steps to install .NET 10.0 with Ubuntu proot-distro.

1. Install Termux from F-Droid.
   • For Samsung devices, you might want to turn off the Auto Blocker feature so that you can install it. You can also use the Play Store version, but we haven’t tested it yet, and your mileage may vary.
2. Open Termux, and let it configure itself. After that, upgrade all packages using pkg upgrade.
   • If you’re prompted to choose whether to keep your own changes or to install the package-supplied version, just press ENTER on your phone’s keyboard.
3. Once all necessary upgrades are complete, you can now install the proot-distro program using pkg install proot-distro.
4. Afterwards, install the Ubuntu 26.04 Docker container with proot-distro install ubuntu:26.04.
   • It might take a while, depending on your internet connection.
5. Now, you can login to the container with proot-distro login ubuntu.
6. Before installing any packages in the Ubuntu proot environment, you’ll have to check to see if there are any package updates with apt update.
   • If there are any, run apt dist-upgrade to upgrade all packages.
7. Install .NET SDK 10.0 or .NET Runtime 10.0, depending on your use case.
   • If you want to build .NET applications, install the SDK using apt install dotnet-sdk-10.0.
   • If you want to just run .NET applications, install the runtime using apt install dotnet-runtime-10.0.
8. If you’ve installed the SDK, verify that the application actually builds.
   • Create a new directory, such as test (mkdir test), and change the current directory to it (cd test)
   • Create a new .NET console project with dotnet new console --use-program-main.
   • Verify that it actually builds using dotnet run.

However, as of now, you may be running into an issue where the building stage of any application may fail with error messages that are similar to this:

 GC heap initialization failed with error 0x8007000E  Failed to create CoreCLR, HRESULT: 0x8007000E 

In this case, you’ll have to add an environment variable that changes the GC heap hard limit value to an acceptable value so that you can build and run applications on Android devices. In order to do this temporarily, append the environment variable before the command, such as this:

 $ DOTNET_GCHeapHardLimit=1C0000000 dotnet build 

If this works, you can add a line that exports this environment variable to your ~/.profile like this:

 $ echo "DOTNET_GCHeapHardLimit=1C0000000" >> ~/.profile  $ . ~/.profile 

Once done, exit and re-enter your proot environment, and you should be able to build and run .NET applications.

Wenn bei euch Windows-Spiele mit Steam/Proton unter Linux nie ein Problem waren, sie nach dem Upgrade auf Ubuntu 26.04 aber nicht mehr starten wollen, kann es evtl. an der neuen Ubuntu-Version oder auch irgendwie am Linux Kernel 7.0 liegen.

Die KI hat mir mehrere mögliche Ursachen und Lösungsmöglichkeiten vorgeschlagen, die alle nichts gebracht haben, bis auf diese hier: Steam als Flatpak-Paket zu installieren. Und tatsächlich, Proton-Spiele starten bei mir jetzt wieder.

Das nur als Hinweis, falls ihr über ähnliche Probleme stolpert.

📢 Ubuntu 26.04 Status Update ⏳

1.5 months post-release, Webinoly is locked, loaded, and ready to ship! However, we are stuck waiting for PHP.

Our ecosystem depends on Ondřej’s PPA, which has unfortunately gone completely silent regarding "Resolute" support.

This delay is entirely out of our hands. We will flip the switch the moment stable PHP packages land. Thank you for your patience! 🛠️

Le frisson de la mise à jour au matin

https://vincentbreton.fr/le-frisson-de-la-mise-a-jour-au-matin/

another day, another Ubuntu upgrade.

- Python 3.14 broke a whole bunch of my tools because the licence file in an add-on library is in the wrong format. Naturally, this makes Python shit the bed and cry.

- GIMP is broken because the ancient script-fu Scheme interpreter is broken, somehow?

- no borders around terminal windows?! How do people overlap windows and stay sane?

- the "... is not responding" window pops up too often

It's very apt that the logo is a trash panda.

Das Upgrade von Ubuntu 25.10 auf 26.04 hat kurzerhand PHP 8.4 deinstalliert... Gut, das liess sich relativ einfach wieder installieren (PHP 8.5). Dann noch ein paar Anpassungen.

Hätte er nicht einfach das alte PHP 8.4 auf dem System lassen können? Oder die 8.5 parallel installieren?

Die Privacy Extensions für IPv6 sind eigentlich eine tolle Idee.

Durch sie bekommen ausgehende Verbindungen eine nur kurzzeitig gûltige IPv6-Adresse.

Allerdings kann das bei Verwendung eines DynDNS-Dienstes zu Problemen führen. Auf denjenigen meiner PCs, die auch aus dem Internet erreichbar sein sollen, habe ich Privacy Extensions darum deaktiviert.

Ubuntu 26.04 hat sie aber beim Upgrade wieder aktiviert, und schon waren meine Nextcloud (samt Passwort-Tresor), mein Paperless, mein SearXNG, mein MollySocket, mein Calibre, mein LibreTranslate, mein LanguageTool... nicht mehr erreichbar.

#Ubuntu2604 #PrivacyExtensions #PrivacyExtensionsIPv6 #IPv6

Na großartig. Bei Ubuntu 26.04 hat sich bei der Konfiguration der IPv6 Privacy Extensions etwas geändert. Die Konfigurationsdatei ist nicht mehr da, wo sie bisher immer war (/etc/sysctl.d/10-ipv6-privacy.conf). Und jetzt sind sie offenbar standardmäßig aktiviert. Heißt, ich erreiche meinen Mini-PC von außerhalb nur noch via IPv4.

Still tracking the Ubuntu 26.04 rollout.

This release introduced several critical low-level changes and improvements that are causing a slower-than-usual turnaround for some upstream packages. While developers work through these complexities, we remain in "stability first" mode.

We’ll pull the trigger on full support as soon as the core stack meets production standards. Thanks for your patience!

Microsoft announces official availability of .NET 10.0 for Ubuntu 26.04 LTS!

Microsoft has announced that .NET 10.0 is now available globally for Ubuntu 26.04 LTS users! This version of .NET brings improved performance and new features, as well as other enhancements across different areas of the framework.

.NET is one of the officially supported development toolchains thanks to Microsoft and Canonical partnering together to ensure that .NET is available and easily installable in Ubuntu. This ensures that .NET works properly across multiple Ubuntu versions.

Ubuntu 26.04 LTS Resolute Raccoon has also seen many changes besides the availability of .NET 10.0, including the usage of Linux 7.0 as the kernel to add support for new hardware and to enhance your computer’s performance and reliability. Besides, .NET 10.0 introduced post-quantum cryptography.

To install .NET 10.0 SDK on your Ubuntu 26.04 LTS installation, follow these steps:

 $ sudo apt update  $ sudo apt install dotnet-sdk-10.0 

Similarly, to install the runtime on your installation, follow these steps:

 $ sudo apt update  $ sudo apt install dotnet-runtime-10.0 

However, to install .NET 10.0 SDK with Native AOT support, you’ll have to install the following packages:

 $ sudo apt update  $ sudo apt install dotnet-sdk-aot-10.0 clang 

To learn more about what’s new for .NET in Ubuntu 26.04 LTS, consult the article below.
