Ubuntu Linux

Sysprof as the system-wide performance profiler for Linux systems is now set to be installed by default on Ubuntu 24.10 and moving forward with future Ubuntu Linux releases. Currently users need to sudo apt install sysprof to enjoy this GUI and command-line driven program but now is to be installed by default on the Ubuntu desktop.

Last Wednesday, we temporarily suspended upgrades to Ubuntu 24.04.1 LTS due to unforeseen issues with dependencies of installed kernel headers after release upgrades. These issues were tracked in bug 2078720 and have now been resolved, and upgrades to 24.04.1 LTS have been enabled again.

...

This issue has been fixed in the APT 2.4.13 update in 22.04 LTS, and upgrades from interim releases have been addressed by a fallback to the previous algorithm in the ubuntu-release-upgrader 1:24.04.23 stable release update. We are adding additional checks to our automated upgrade testing to prevent similar issues in the future.

If you are affected by this issue, you can run apt install --fix-broken to remove the old kernel headers and make apt operational again.

As a lifelong Windows user I've just for the first time switched to Ubuntu and I'm learning how to navigate the system but I haven't found an easy way to update my Carbon's X1 Gen 6 BIOS from its hard disk and would appreciate any advice.

I'd be also happy to hear what I should do as a newcomer to Ubuntu to make my experience with it better and have an easier time overall.

A blog post about all the official and community wallpapers in the upcoming Ubuntu 24.10 Oracular Oriole.

Last week, the first point release of Ubuntu 24.04 LTS arrived and with it, upgrades from Ubuntu 22.04 LTS enabled.

Only, those upgrades didn’t go work out well for everyone.

So Canonical has hit pause on upgrades to Ubuntu 24.04 LTS from Ubuntu 22.04 LTS.

...

In reply, Canonical says it halted upgrades “due to a critical bug in ubuntu-release-upgrader in the way it’s using the apt solver” (though other, recurring, issues have been filed on Launchpad and mentioned on social media since last week).

The default wallpaper of Ubuntu 24.10 ‘Oracular Oriole’ (and its official mascot artwork) has been revealed — along with an extra 20th anniversary surprise!

Introduced as part of the Ubuntu 24.04 LTS roadmap late last year (but couldn't make it to the final release), the Flutter-based Security Center is a dedicated application for Ubuntu meant to bring out the hard-to-access “ninja security” features of the distro.

The developers want to focus on four key areas with this app. One is that they aim to make it easy to handle full-disk encryption. The second is that they are planning to move the Ubuntu Pro settings from the “Software & Updates” app into a dedicated section in the new security app.

The third is a dedicated “Network” section for facilitating easy firewall control and enabling “Stealth Mode”. The final one is to introduce a prompting mechanism for apps; more on this one later.

Currently, the Security Center features only a single experimental option to require Snap apps to ask for system permissions. I tried enabling it after installing Security Center on an Ubuntu 24.04 installation on a virtual machine, but it just sent me into a loading loop.

Ubuntu Core Desktop is an immutable distro, takes a different path than most other immutable distros.

• The entire OS is built using snaps, including the kernel and bootloader
• Uses snaps instead of flatpak
• Prefers LXD over distrobox and other projects that use podman

After a two-week delay, the Ubuntu 24.04.1 LTS release was published today by Canonical for all official flavors as the first point release to the long-term supported Ubuntu 24.04 LTS (Noble Numbat) operating system series.

...

In addition to all the updated packages, this first point update to Ubuntu 24.04 LTS also makes it easier to join Ubuntu machines into Windows estates with Active Directory integration and (finally) enables upgrades from Ubuntu 22.04 LTS (Jammy Jellyfish) systems.

From Ubuntu Discourse: Noble Numbat Point-Release Changes

Official Announcement: Upgrade your desktop: Ubuntu 24.04.1 LTS is now available

Thanks to the Canonical decision to commit to shipping the very latest upstream Linux kernels in Ubuntu releases moving forward, Ubuntu 24.10 shipping in October will have the Linux 6.11 kernel that is debuting as stable in mid-September. Canonical's kernel engineers are currently preparing for rolling out that new kernel version in the Oracular Oriole archive.

From Discourse Announcement: Introducing Kernel 6.11 for the 24.10 Oracular Oriole Release:

Given the current schedule of the upstream 6.11 development cycle, with 6.11-rc5 released on 2024-08-25, Ubuntu 24.10 will be considered a Tight Release from the kernel standpoint. This means that the Ubuntu 6.11 kernel included in the 24.10 release might have some limitations or known issues that will be addressed after the release.

This tutorial shows how to enable zswap kernel module to increase usable RAM in your Ubuntu computer or laptop.

...

Swap space can be helpful for computers with limited RAM. But, it’s slow! Too much swap in use will slow down the overall system performance.

As workarounds, Linux includes 2 kernel modules: zram and zswap. Instead of moving inactive pages from memory to disk (swap space), they do similar things by compressing the data into dynamically allocated RAM space.

...

zram creates a block device in RAM, that acts as swap space (or a general-purpose RAM disk). When system needs to swap out inactive pages, zram compress them into the block device. No swap on disk is required.

zswap is a lightweight compressed RAM cache for swap pages. It attempts to compress the pages, that are needed to swap out, and store them into a memory pool in RAM. Poorly compressible data is directly written to disk (swap space). And, when the memory pool is full or the RAM is exhausted, the least recently used page is decompressed and written to disk (swap). A swap space on disk is required!

We’re looking for motivated people that want to join the Ubuntu Community Council!

The Community Council is the highest governance body of the Ubuntu project. They handle Code of Conduct violations, mediate conflict, and support the community.

...

The Ubuntu project turned 20 this year, but is still in constant flux. The advent of new communication platforms, new projects under our umbrella, and the ever-growing popularity of the project requires our community to evolve. We need to make sure Ubuntu is set to tackle the challenges of the next 20 years. It needs a strong and active community council to guide the project forwards.

• You show humanity, gentleness and kindness in your communication.
• You create a welcoming atmosphere.
• You want to invest time in the next two years to handle CoC violations, mediate conflict and help improve the Ubuntu community.
• You are willing to regularly meet with the other council members

...

Nominations are now open and will close on Sunday September 22th, 23:59 UTC. After that, the Community Council will review the submissions and will set up an election.

The DC-ROMA RISC-V Pad II boasts a 10.1 inch (1920×1200) IPS 10-point touch display, and is powered by the same SpacemiT K1 SoC found in their RISC-V Ubuntu laptop (which launched with a confused set of pricing tiers and availability).

That chip comprises eight 64-bit RISC-V cores running up to 2.0 GHz, plus the RVA 22 Profile and 256-bit RVV 1.0 standard to provide “powerful AI capabilities”, and an Imagine Technologies BXE-2-2 GPU, a baseline 800 MHz effort.

Memory wise, the base model offers 4GB LPDDR4 RAM. 8GB and 16GB options are available at extra cost. All versions have 64 GB eMMC, but the 16 GB variant can also be equipped with a 128 GB eMMC – all those upgrades bump the cost, of course.

Also present is a 6000 mAh battery, front and rear cameras, a USB Type-C 3.0 port (with DisplayPort), and a 3.5mm audio jack.

The DC-ROMA RISC-V Pad II ships with Ubuntu 24.04 out the box, but DeepComputing say the 16GB model will also support (a custom build of) Android 15 AOSP in time.

With the exception of critical security issues/bugs, Canonical will be skipping over shipping stable release updates for the Linux kernel in Ubuntu until early October.

From email announcement

Please be informed that we will be skipping the SRU cycle 2024.09.02 due to a critical infrastructure change. This adjustment will allow us to focus on ensuring a smooth and stable transition. Our next SRU cycle will start when the infrastructure is back online. The current estimation is at the beginning of October. Once we know more details, we will let you know the exact date.

October is fast approaching and with it the Oracular Oriole! As with any new release of Ubuntu, our team of developers from Canonical and the community work hard to ensure it’s stable and bug free. You can join our intrepid army of testers and help them squash any sneaky bugs that remain!

This Ubuntu Testing Week kicks off on August 22nd and runs until the 29th. During that stretch, we encourage everyone to grab a copy of the latest build, run some tests and share your results.

I have a mini PC running Ubuntu. I use docker portainer to house Plex and all of the arrs services.

Due to playback issues which I assumed were due to EAC3 audio (a common issue which others reported), I removed Plex from docker and installed it outside.

To my frustration I am still getting buffer problems, so I downloaded the log file. This appears to be reporting constant network notifications. I have copied an extract below.

I have an ethernet cable plugged into the PC and (when I was using Windows pre Ubuntu) I have reserved the IP address in the router for the MAC address for the ethernet adaptor.

I have no idea where to start in troubleshooting this. Is the WIFI adapter trying to connect? Or is the docker network interfering? I have no experience with this so would be very grateful for some pointers.

With this First Look, we will be taking a look at “Tiling Shell”, an open-source window tiling solution for GNOME-equipped systems.

Some key highlights of Tiling Shell include:

• Easy multi-monitor operation.
• Windows 11-like snap assistant.
• Can be used on GNOME 40-46.
• Supports both X11 and Wayland.

The level of control it gives is impressive, there are options to tweak the inner/outer gaps between windows, enable snap assistant, configure the tiling system, add keybinds for window management, and more.

In terms of the layout choices, the possibilities are endless (literally), there are some handy pre-configured ones that are usable. But, the main highlight is the layout editor, which is the star of the show.

As for how the multi-monitor experience is, Tiling Shell doesn't disappoint in that matter. It's easy to tile windows between workspaces and displays using the snap assistant, I didn't feel that this behavior was an add-on, it felt quite native to me.

Prior to the Ubuntu 24.10 feature freeze, the GNOME 47 beta has landed for Ubuntu 24.10 daily builds. The GNOME 47 desktop will be providing the out-of-the-box experience on Ubuntu 24.10. This was expected to happen and great to see it carried out given all the great GNOME 47 changes upstream from Wayland enhancements and more.

Canonical engineers have also continued spending a lot of time on further enhancing the Snap experience on Ubuntu for these sandboxed apps. Ubuntu 24.10 now has progress bars in the dock for Snaps that refresh in the background, improved Snapd handling for the latest NVIDIA graphics driver to behave better with the Steam Snap, seeded Snap tracks for desktop apps, and better Snap track migration handling on Ubuntu upgrades. Ubuntu 24.10's App Center has also seen improvements with its "Manage" page, among other refinements.
