I think the “Ubuntu Core 22” means it is the snap based version of Steam rather than the deb version.

If you look at the snapcraft.yaml for the Steam snap, it uses core22 as its base.

Looks like a number of patches are landing in Ubuntu to address this: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/2082335

Update: CUPS Remote Code Execution Vulnerability Fix Available

This is a great summary. Thanks!

It looks like you are running XFCE instead of GNOME (the normal Ubuntu desktop). I’m not sure how that happened… but you an always just install another desktop.

For instance, you can try to make sure you have the ubuntu-desktop or ubuntu-desktop-minimal metapackage installed:

sudo apt install ubuntu-desktop-minimal

After that, the login manager should allow you to select the Ubuntu session rather than the XFCE one.

Still using mutt after two decades (with isync for fetching).

Yes, based on the diagrams on their blog, it looks like this only impacts Snaps.

From the Discourse Blog:

The Linux desktop provides XDG Desktop Portals as a standardised way for applications to access resources that are outside of the sandbox. Applications that have been updated to use XDG Desktop Portals will continue to use them. Prompting is not intended to replace XDG Desktop Portals but to complement them by providing the desktop an alternative way to ask the user for permission. Either when an application has not been updated to use XDG Desktop Portals, or when it makes access requests not covered by XDG Desktop Portals.

Since prompting works at the syscall level, it does not require an application’s awareness or cooperation to work and extends the set of applications that can be run inside of a sandbox, allowing for a safer desktop. It is designed to enable desktop applications to take full advantage of snap packaging that might otherwise require classic confinement.

So this looks like it complements and not replaces the XDG Desktop Portals, especially for applications that have not implemented the Portals. It allows you to still run those applications in confinement while providing some more granular access controls.

On Ubuntu, there is a program called “Firmware Updater” which uses LVFS to retrieve and install firmware updates (including BIOS/UEFI).

According to this page: https://fwupd.org/lvfs/devices/com.lenovo.ThinkPadN23ETXXW.firmware your Carbon X1 Gen 6 should be supported.

I think you meant Pop!_OS (is developed by System76). TuxedoOS is developed by Tuxedo Computers, which is a European Linux focused hardware company.

That said, the point stands… there are hardware companies making Linux supported devices.

The default “App Center” does not support flatpaks (only snaps). However, if you install the GNOME software center with the suggested dependencies:

$ sudo apt install --install-suggests gnome-software

Then you will be able to install flatpaks, debs, and snaps.

I think the WINE project was maintaining a fork of Mono that was used to support running certain Windows applications:

So in addition to translating traditional WIN32 system calls, WINE also supports .NET applications, which a number of Windows programs require.

Depends on your perspective, I guess. To me, GNOME is now pretty mature, stable, and reliable. That is one of the reasons why I left Pop-shell for a more vanilla GNOME experience.

COSMIC has a lot of hype right now, but based on my experience (and others), it is not at all stable or ready as daily driver. That is not to say it isn’t exciting but at this point in time I value stability and being able to just use my computer and GNOME provides that.

As the Linux luddites used to say, not all change is progress :)

Coincidentally, I received a firmware (EFI) update from Dell today via LVFS. Really nice that it works so smoothly on native Linux (no more manually downloading firmware to USB drives, or relying on Windows).

This reddit post seems relevant. A user mentions:

I found out that only the containers having these kind of networking problems where all running the container in “host” networking mode.https://docs.docker.com/network/drivers/

Since I don’t need host mode, I can just comment that line out, and it will start using the standard Bridge (which will be used by default if you don’t specify any networking settings for your containers)

This is running under docker as you had in your initial configuration.

Another reddit post mentions setting the gateway and DNS server if you have a static IP:

It turned out to be nothing to do with Plex but rather was the fact that there was missing information on my static IP setup. Once I added in the gateway and DNS information those extraneous messages went away.

I’m not sure if that will help, but it’s perhaps something you could consider as you debug this issue. Good luck.

The reasons for this shift in budget away from funding Free Software and the NGI initiative seems to be an allocation of more funds for AI, leaving internet infrastructure by the wayside. Meanwhile, the EC has thus far declined to comment to share its official reasoning for striking this funding from its budget.

Sigh. It appears that they are chasing after the latest “shiny” thing instead of investing in existing infrastructure. Not surprising, but disappointing.

+1 For xournal++. That is what I usually use for annotating slides and drawing with my wacom tablet.

I’m a masochist, so I usually do “New”. Lemmy is small enough that I can usually get through most of the new posts in a reasonable amount of time.

That said, if I want to a bit chiller experience, I will use “Scaled” which sometimes bubbles up something I might have missed.

Finally, I will use “Active” if I’m really bored and what to see what most people are engaged with… but that is pretty rare.

It should be noted that Ubuntu 24.04 comes with Tiling Assistant, which provides some basic manual tiling features but not as extensive as Tiling Shell described in the article.

That said, from my personal experience, the provided Tiling Assistant is good enough for my workflow and that’s what I use without any major issues.

I currently use Ubuntu for all my machines (desktops, laptops, and servers), but I used to use Void Linux on my machines for about 6 years, including on a couple of VPSes. Since you are familiar with Void Linux, you could stick with that and just use Docker/Podman for the individual services such as Matrix, Mastodon, etc.

In regards to Debian, while the packages are somewhat frozen, they do get security updates and backports by the Debian security team:

https://www.debian.org/security/

There is even a LTS version of Debian that will continue backporting security updates:

https://www.debian.org/lts/

Good luck!

Not a bad list. Off the top of my head, I would say it is missing two things:

1. Discrete Math (formal logic, sets, probability, etc)
2. Theory of Computing (not just algorithms, but things like Turing machines, NFAs, DFAs, etc.). These may not be strictly the most practical courses, but I think a Computer Science degree would be incomplete without these.

The “Introduction to Operating Systems” link no longer works (redirects to “Autonomous Systems” courses). Instead, I would recommend using Operating Systems: Three Easy Pieces, which is the textbook I use in my OS course.

Finally, something like The Missing Semester of Your CS Education would also be a nice extra.
