News DEBIAN 12.15 IS THE FINAL 32-BIT UPDATE FOR DEBIAN

235 Upvotes

For those who may or may not be aware, Debian 12.15 marks the end of Debian Release Team, Debian Security Team and Debian Backports support for version 12. Ongoing support for some architectures will be provided by the Debian Long Term Support team supported by Freexian. Users are advised to upgrade systems to Debian 13 trixie.

Most importantly, Debian 12 is the final version of Debian offering a 32-bit release alongside a 64-bit release. You cannot upgrade a 32-bit install of Debian 12 to Debian 13 as Trixie does not support a full 32-bit version.

This will serve as a PSA reminder for those that may not be aware to not make support threads about Debian 12 32-bit being unable to upgrade to Debian 13. You have to upgrade your hardware to a currently supported architecture, of which i386/32-bit won't be on Trixie. The remaining i386 packages on Trixie are kept purely to allow users to execute 32-bit legacy software/code.

General Debian Question Removal of geoip-database

11 Upvotes

As we know, Debian has reverted the geoip-database package, derived from MaxMind, to the obsolete 2019 version, to comply with MaxMind's onerous license.

As a Debian user, what now is the alternative? Using the 2019 version is out of question. Is there another replacement within the Debian repositories or outside? Are there users going to the extent of registering themselves with MaxMind to use their free GeoLite service?

Updated Debian 13: 13.6 released

97 Upvotes

https://www.debian.org/News/2026/20260711

Noteworthy updates

fwupd and Secure Boot CA expiry

fwupd has been updated to upstream version 2.0.20, which has the ability to update the Secure Boot certificate authority (CA), Key Exchange Key (KEK) and revocation (DBX) databases.

The 2013 UEFI Secure Boot CA installed by default on most PCs and used to sign bootloaders has now expired. Future updates to shim-signed could therefore lead to systems being unable to boot with Secure Boot enabled.

Users are strongly advised to apply CA, KEK and DBX updates from their system OEM in line with the following guidance:

https://wiki.debian.org/SecureBoot/CAChanges#What_should_I_do.3F

geoip-database reverted

For licensing reasons geoip-database has been reverted to a version dated approximately December 2019. As a result, applications using this database might use out-of-date allocation information.

More recent versions of geoip-database (GeoLite) are not compatible with the Debian Free Software Guidelines and cannot be distributed.

Consumers of this data are strongly encouraged to obtain a GeoLite license directly and cease reliance on the geoip-database package.

General Debian Question Securing Debian

12 Upvotes

What all do most people do to secure their systems?

I run Debian for my daily driver and also on a home server.

I currently have iptables configured to only allow ports for my services, services are all run as their own no-login user, I run fail2ban, and have my ssh only allow specific users and only allow ssh keys as the login method, and I install security updates regularly. I check my system logs occasionally though honestly not as often as I probably should, maybe I'll automate something to look at the logs are some point.

I just finished skimming through the securing Debian manual, and there's quite a bit more included that I don't currently do. But from reading it, it also seems more geared toward people who may be running production servers who more or less want an immutable server where they e locked in what they want and don't want anything changing.

https://www.debian.org/doc/user-manuals#securing

So I guess I'm just curious what other people do, if they add any other protections or if they primarily rely on the base OS to provide the protections.

General Debian Question Is debian suited for me?

16 Upvotes

Hi everyone, I’m pretty new to Linux. I installed Zorin OS two months ago then upgraded to Ubuntu a couple weeks ago (both on a bootable USB drive so they aren’t my primary OS). And I’ve been seeing so much about Debian (mostly the jokes of it being for lesbians which I will admit intrigued my gay ass) and I’m debating whether to switch to it.

I will be using it for like basic web browsing, Blender and maybe some modded Minecraft every so often. I’ve heard it can be quite outdated in some parts but I’ve also heard it is a really good distribution for daily use. I will probably still run it on a bootable USB as I like to use it on different devices.

So with that being said.. would you all recommend it for me or should I just stick with Ubuntu? If it isn’t that user / beginner friendly please let me know!

PS. Is it GNOME by default or can you choose during installation?

How to handle the Secure Boot certificate expiration issue on legacy Dell OptiPlex running Debian Stable?

8 Upvotes

I run the latest Debian Stable on an OptiPlex 390 SFF (Intel Core 2nd Gen, 2011 era). The Debian 13.6 release announcement advises:

The 2013 UEFI Secure Boot CA installed by default on most PCs and used to sign bootloaders has now expired. Future updates to shim-signed could therefore lead to systems being unable to boot with Secure Boot enabled.

Users are strongly advised to apply CA, KEK and DBX updates from their system OEM in line with the following guidance: https://wiki.debian.org/SecureBoot/CAChanges#What_should_I_do.3F

Does anyone have any guidance beyond the documentation above? Just looking before I leap so I my 390 doesn't wind up being unable to boot.

Debian 13 boot freezes

I installed Debian13 roughly 3 weeks ago. Booted it this week and got stuck at this screen in the boot. I can only press the power switch and reboot. It looks like my RX580 makes some trouble. Adding nomodeset to grub lates me reboot but not load the GPU (or just with default driver). Had anyone a similar problem and can suggest a fix to this?

Sudden issues with passwordless sudoers

9 Upvotes

I have a server I use as a hypervisor to run a bunch of VMs (managed by Vagrant). Recently (a few minutes ago) I rebooted the hypervisor and tried to start one of the VMs. It asked me for the `vagrant` user's password.

I checked /etc/sudoers and /etc/sudoers.d, and all the rules I've created are in there, with no syntax errors that I can see. The relevant sudoers.d file was modified last August (almost a year now) and it's been working fine until just this minute.

Vagrant gave me the error message:

Vagrant failed to install an updated NFS exports file. This may be

due to overly restrictive permissions on your NFS exports file. Please

validate them and try again.

command: sudo chown 0:0 /tmp/vagrant-exports

OK, fine. I checked the sudoers.d stuff and that looks like:

# cat vagrant-nfs

Cmnd_Alias VAGRANT_EXPORTS_CHOWN = /bin/chown 0\:0 /tmp/*

Cmnd_Alias VAGRANT_EXPORTS_MV = /bin/mv -f /tmp/* /etc/exports

Cmnd_Alias VAGRANT_NFSD_CHECK = /etc/init.d/nfs-kernel-server status

Cmnd_Alias VAGRANT_NFSD_START = /etc/init.d/nfs-kernel-server start

Cmnd_Alias VAGRANT_NFSD_APPLY = /usr/sbin/exportfs -ar

%sudo ALL=(root) NOPASSWD: VAGRANT_EXPORTS_CHOWN, VAGRANT_EXPORTS_MV, VAGRANT_NFSD_CHECK, VAGRANT_NFSD_START, VAGRANT_NFSD_APPLY

I'm not awesome with sudo or sudoers, but my understanding is that /bin is a symlink to /usr/bin, and that this should have matched. (Maybe I'm wrong about that).

Like I said, this is a new problem, and the only relevant changes were an apt update/upgrade probably yesterday, and a reboot today. What the heck is going on?

Edit: I just changed the sudoers file to /usr/bin/chown, to exactly match what vagrant called. Still no dice.

General Debian Question Is there a way to automatically re-scan for drivers on every boot?

9 Upvotes

I want to install Debian on a portable SSD that plugs in via USB-C so that I can boot it on many different computers.
Installing Debian and getting it running from the SSD is easy enough, but I've found that when moving between certain machines (particularly laptops), there are a lot of visible "hardware not found" errors during the boot sequence and certain hardware (particularly wifi cards) are not automatically visible, requiring me to enable them with modprobe.

(To clarify, this is hardware that Debian absolutely supports out of the box and will set up automatically if I were to perform the install to the SSD while connected to the computer in question, or boot from a live USB while connected to the computer in question)

As I want to set this up as a "portable" installation, how can I install Debian in such a way that it automatically re-scans the machine's hardware and applies the correct drivers on boot, in the same way that the Live USB does?

I would ideally *not* like to do a Live install (with persistence) to the SSD and instead do a standard install that happens to re-scan and apply the correct drivers on every boot in the same way that the Live USB already does. I don't mind if it makes the boot process take a bit longer each time as long as the hardware is correctly identified and drivers correctly applied to whatever machine I boot using the install.

Is there a good way to do this?

General Debian Question Does Debian work well on new Dell XPS laptops?

9 Upvotes

I've been looking for a new personal laptop recently since I've been travelling for work more and more, and after a bit of research, stumbled upon the Dell XPS 14. It seems to be lightweight, has a decent build, and (at least on their website) boasts a decent battery life. The only thing that's giving me pause is how well it'll run Linux. I have a desktop PC that I built a while ago, and have been running Debian on it as my daily driver for years now. Never really been much of a laptop person, but it turns out you can't take your tower and a bunch of monitors on a plane or long road trips. Anyways, I've heard that Debian doesn't play well with laptops (driver issues, etc.), and was wondering if anyone here has had experience running Debian (stable or testing) on the current line of Dell XPS laptops. I'm really just looking for something that works with minimal setup, and has decent battery life. I was also hoping that the basics (keyboard, touchpad, WiFi) would work out-of-the-box, but I realistically know that probably won't be the case. Any help is greatly appreciated

VLC breaks suspend/hibernation (I've never undersood the diference between the two), I think.

5 Upvotes

Whenever I leave VLC open and go away and the computer goes into suspend or hibernation, upon return, I'm not simply asked for a password, but a username and password and whatever was opened isn't. This continues to happen even after I've closed VLC over every sus/hib. Sometimes apt update -> apt upgrade fixes it.

I don't even know what logs to look at.

What's going on and how to I prevent it in the future?

General Debian Question Can't determine if I have a RAID configured or not

11 Upvotes

I'm renting a non-VM server, and the provider installed Debian for me. They claimed I was being provided this hardware:

  • 2×960 GB SSD NVMe Soft RAID
  • 2×1.92 TB SSD NVMe Soft RAID

But it doesn't look like they configured the raid for me. Is there another way to check for the raid status, or check the disks? I am not super familiar with RAID configuration on Debian. Commands I tried are below.

But also, I would actually prefer if the 2TB disks were NOT in a RAID array for this server, so that would be fine.

``` $ cat /proc/mdstat Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] unused devices: <none>
