Title: Update of 12-12-25 ruins the system?
Post by: alexsid on 2025/12/12, 08:37:15
Hi!
Todays update seems to remove xorg and ruin the system. Two attempts to install it via Discover or terminal sudo apt full-upgrade were unsuccessful. Had to restore from Timeshift.

Same here. Xorg will be removed. So will have to wait...

For shure. Main pakages like this will be fixed soon. You will not be the only one having this problem. As you can see in the output of your pakagemanager that the complet xorg installation is deprecated right now. Actuall I'm not sure which pakage is cosing the problem.
But how are you upgrading your system? You are not using a pakagemanager like Discover doing this job, or?

Better run apt / apt-get in a terminal upgrading your system!! (read the manuals )

While writing this post here in a terminal apt-get update /apt-egt dist-upgrade is running fine and system is upgrading ;-)

I do assume the culprit is "xkb-data". [apt-get (dist-)upgrade does not ;) upgrade it (now).]

I just dist-upgrade and xkb-data is being held back for some reason. If I try to manually upgrade it much of X11 will be removed. We'll have to wait for a solution. There seams to be a conflict.
apt depends xkb-data
xkb-data
  Breaks: x11-xkb-utils (<< 7.7+5)
Title: Re: Update of 12-12-25 ruins the system?
Post by: michaa7 on 2025/12/12, 13:15:36
Here apt does not upgrade xkb-data.

@ alexsid
Whatever is happening here, it's a reminder of what you get if you do not care about what apt is telling you in the "remove" section of it's output. And if discover hasn't shown packages to be removed you never ever should use it again.

BTW,
Quote... apt full-upgrade were unsuccessful
will never know what package you miss and repair your system.

Right thing to do would have been apt install xorg which most likely will give you an apt error due to missing dependencies, which packages in a second, third ... try you'll have to append to the install command until it succeeds.

My question is as follows:
Will and when this issue be fixed by Debian or Siduction team? Or shall we find an effor themselves and fix it personally?

Well, the Debian developers are not "retarded", and since even the xkb-utils(!) do not fit the xkb-data package, I expect for the problem to go away within the next 24 to 48 hours.
It would be madness for the Siduction community to try and handle such an extensive number of depending packages. The only thing I could imagine is, for them (@towo?) to provide an older fitting xkb-data package in the meantime for those which can not install(!) the X11-System right now. All others should just sit it out.
[If you are experienced enough, you may have a look at the stable (trixie) and/or testing (forky) xkb-data package - may be it suffices.]

Hopefully it will be resolved quickly. Will a standard apt-update && apt-full dist-upgrade suffice to get the system working again? I ask because I am new to rolling Debian Sid. I would be very disappointed if my system stopped responding now that everything is installed. Anyway, I now know that I don't have to follow discover to the letter in order to perform an update. Unfortunately, this had to go hand in hand with a system that is now unusable.

I did sudo apt full-upgrade first. And got the issue. So it would be wise to wait for a day or two till the issue will be resolved.

So why didn't you read the apt output where all packages to be removed got listed?

The same goes for you, darknetmatrix. As you are new to sid(uction), here one of the most important advices: read the apt output every time and never ever upgrade blindly. Never ever! Otherwise it's like crossing the street without looking at the trafic lights. And then, when you got hit, asking "why?" and "will it get fixed?".

As long as there are no extensive new removals :), you should just do the "full-/dist-upgrade". But since packages were removed previously, not all of them are guaranteed to come back automatically. You could follow @michaa7's advice to do an  apt install xorg.
If you are really curious and willing to install some time, there is a file /var/log/apt/history.log which logs all apt activities, where you can read about the previous removals and then re-install any missing. It is often useful to install only "main programs" (first), not libraries or e.g. "-data" files or the like, since many of them are dependencies, which will be automatically installed also. Anyhow, you can "recover" any package previously removed, this way.

I've learned my lesson for today. Hopefully this will be resolved quickly, otherwise I'll be forced to do a new installation.
Is it also the case in a new installation that all updates would come in and there would be no working system again?

That depends on how you install your system. When you are e.g. doing it from a Siduction ISO, all packages of programs that come with it are already installed (and will not vanish ;)). All additional packages can/will only be installed if all dependencies are met. So on a "full-/dist-upgrade"(du), saying "yes to all", yes, they may get removed again.
Advice is: If a "du" threatens to remove anything you want to keep and that is not just because of a newer version is available, then do not do a "du", but just an "upgrade". This will not remove anything (without replacement) from your system. Just try a "du" from time to time, saying "no" to it as long as anything would be removed, you want to keep.

Interesting...  For me, using apt, I had nothing removed (and all is working) and xkb-data is listed in "Not Upgrading" section.  I think this might be due to the new solver, but I am surprised that at least a few siduction users did not have it held back as well.

Just a simple apt update & apt upgrade  ;D

xkb-data issue (caused by keyboard-configuration apparently):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1122650

And the other issue looks like glibc source package was updated, but some of the packages are unavailable (libc6:i386?)

@ darknetmatrix

But remember: It IS recomended not to use "apt update" regularly, it is a last resort if you need to update, but can't dist-upgrade for whatever reason. Your system NEEDS do be in syc with the general progress of the entirety of packages, which you can only achieve by using "apt dist-upgrade".

Do yourself a favor NOW and issue "apt update && apt dist-upgrade" AND THEN READ, especially the remove section, bevor pressing Y or N. Nothing evil can happen until you press "y". And try to understand the apt output. Ask if neccessary. Most likely apt will not remove the packages discover did.

Long story short: "apt upgrade" is NOT the recommended way of keeping your system up-to-date! It is not the better way!

I recommend Timeshift. It's in the Repos and once set up, updating is stress-free, because you can go back easily to a working state before at any time.

just did the apt du, rebooted the machine and posting from it, so everything is working fine now :D.
Updates from now on will be in the terminal and not anymore in 'discover', lesson learned.

Yes, apt solver is definitely a great option. For me it's built in. If there is a bad package situation apt will tell me which one and hold back the package. You should have the same thing by default. If not use apt solver.
apt dist-upgrade
The following package was automatically installed and is no longer required:
  libsimdutf27
Use 'apt autoremove' to remove it.

  debhelper  libdebhelper-perl

Those are a list of abandon packages. Especially that old kernel. I would make sure there is nothing on the list you absolutely need(likely not) then purge them. It says to use apt autoremove but you better off to use apt autopurge. This will get rid of any config file as well.

No.

1) dist-upgrade and full-upgrade are exactly the same, one is just a link to the other (they are still both existing due to historical reasons)
2) --solver 3.0 is the default solver since a few weeks ago, so no need to select it manually

apt update alleine ist immer unbedenklich und notwendig, um überhaupt zu sehen, welche Aktualisierungen anstehen.

Die Entscheidung ob und was bzw. aktualisiert wird (apt upgrade oder apt full-upgrade) triffst du dann danach.

That looks like a completely different issue than the problem with xkb-data (which was what this thread was originally about): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1122650
You should probably start your own thread. Somehow, this thread turned into a general discussion of apt solvers, Discover, etc.

The bottom line is that folks either need to wait for that bug to be fixed, or, if they can't wait for some reason, they can probably cleanly upgrade everything but xkb-data. But I doubt Siduction devs are going to endorse "selectively" upgrading like that.

Until xkb-data is fixed upstream there is nothing to do but wait. It currently does not have any effect on the system and apt is holding it back. With Sid this happens time to time. That's why it's called unstable.

Well, (for me) it takes too long for the Debian maintainers to fix this thing, which has an immense impact. I am really disappointed. Would someone try an "ab ovo" install of sid/unstable, without coming from a working ISO - like Siduction -, a reasonable X11 install is as good as impossible.

Yes, it's a good idea to have a secundary Linux installed, with the most wantet progs, I am use as secundary debian (old)stable.

My personal way to updates/upgrades:

- looking for upgrade warnings here
- reboot the computer
- switch to a tty: press strg+alt+F3  (don't use a konsole/terminal under X!!!), or, if I'm on an other computer, I'm using ssh with screen
# systemctl isolate multi-user.target; apt update && apt -d full-upgrade
The -d in apt -d full-upgrade does only download the packiges but do not install them. (i use it in a script named mupgr.sh)
- take a look for the summery, if I'm not sure, I look to the details...
- okay:
# apt full-upgrade
- not okay:
# apt upgrade

hope it helps and please excuse my bad english

Currently there is no need to intervene with apt. If you apt dist-upgrade you will be presented with the list of packages to be upgraded. It will also tell you if there are new packages to be installed, if anything is to be removed and if there are any hold backs to prevent breakage.

Not sure if this is the same issue I'm having, I see in this thread that it started on the 15th, but I know that I have dist-upgraded then, and also dist-upgraded on the 16th, but I couldn't boot my intel graphics HD 620 laptop today on the 17th.
I also dist upgraded on the same schedule my good laptop with nvidia graphics in the same days, and it just works today, so this would point to an issue with the i915 driver.

A chatgpt session had me trying to install kernel 6.6, and to disable guc in grub, but nothing changes.
The only way to get a stable tty3 shell is by booting 6.17-11, and do Ctrl-Alt-F3 while there is a solitary blinking cursor where gdm should appear.
If I use any other kernel, or if I try the enable_guc=0 edit, the system will just freeze making it impossible to do stuff in tty3 or sometimes even access it at all.
Sometimes Ctrl-Alt-Del will work to reboot the system anyway, some other times I will have to keep the power button pressed to turn it off.

I couldn't install xserver-xorg to fallback on xfce and be able to access the system, because of a dependency issue ("blahblah is not going to be installed"), and I also have the xkb-data not being upgraded in both laptops.
Running Gnome wayland on both laptops.


I am now scared to try and reboot my good laptop for fear of having an unworkable system here too, and I kinda need this to work.

an easy fix is to reinstall version 2.42 that you can download from e.g. https://ubuntu.pkgs.org/25.04/ubuntu-main-amd64/xkb-data_2.42-1ubuntu1_all.deb.html
Then I used synaptic, locked the package version of the downgraded xkb-data(2.42.1) and then reinstall xorg and deleted packages.
it worked for me.

does this mean that the whole woe comes from the xkb-data package being held to an older version? I don't particularly recall any removals happening during dist-upgrade (except me autoremoving unneeded packages), and xkb-data is at version 2.42-1 which is the same you linked to

Again, Siduction works fine with a held back package. You need to pay attention to what apt is telling you. You would have been notified that x11 plus was being removed and you said yes. You got what you asked for. There is no way I would install a Ubuntu package. You could be creating more problems than you started with.

The current situation is not a new one. This happens once a year and should not come as a surprise if you are running Sid. As a permanent fallback, I have been using a Tumbleweed (a rolling release, too) for years, and it works fine whenever needed. Nevertheless, Debian Sid is inherently risky but challenging. In the worst case, I might have to wait a couple of weeks to get back on track; that is Sid by nature.

My experience over the decades: always have a backup or alternate system (LTS, or even better, an alternative and non-Debian distribution) — we're talking about 20 to 30 GB of disk space here. It's wise to wait before you downgrade. Swapping your home directory from A to B is not that complicated. There may be some inconveniences, but no serious issues.

And in doubt, a simple apt update and apt upgrade (not dist-upgrade or full-upgrade) might help for a while.

Title: Re: Update of 12-12-25 ruins the system?
Post by: Teriarch on 2025/12/17, 23:03:30
Here is the problem:

Recent Debian package keyboard-configuration_1.244_all.deb depends on
Depends: [...] xkb-data (<< 2.42A)

We can easily fix the dependency to
Depends: [...] xkb-data (<< 2.46A)

The system now happily installs the offending package xkb-data_2.46-1_all.deb, but we
run into another very delicate problem: xkb-data_2.46-1_all.deb replaces former
directory /usr/share/X11/xkb by a symbolic link of the same name (pointing to
/usr/share/X11/xkeyboard-config-2), which contains all necessary config files.

But since the old directory already exists, the package manager fails to remove it
in favor of the new symbolic link of the same name (I think this is a bug of the package
manager) with severe consequences:

Sddm is still depending on Xorg in order to start the greeter, but Xorg cannot find its
configuration files in  /usr/share/X11/xkb, since the directory is empty as a consequence
of xkb-data's update and the missing symbolic link. So Xorg fails to start and therefore
the screen remains blank. Now that we know, here is the fix:

1) Modify the ../DEBIAN/control file of keyboard-configuration_1.244_all.deb
by the following lines:

Version: 1.244b
Depends: debconf (>= 0.5) | debconf-2.0, liblocale-gettext-perl, xkb-data (>= 2.42~), xkb-data (<< 2.46A)

Install the modified package and du to include the recent xkb-data_2.46-1_all.deb file.
Remove  /usr/share/X11/xkb:

$ sudo rmdir /usr/share/X11/xkb

Manually create the missing link:

$ cd  /usr/share/X11
$ sudo ln -s ../xkeyboard-config-2 /usr/share/X11/xkb

That does the trick.

Regarding my setups, I made a "mistake" by shutting down my good laptop with nvidia card when I got off it, but when I just turned it back on, yes it gave me a small stroke because the blank screen with cursor on top left stayed on for one too many seconds, yet at the end GDM greeted me.
This laptop is better specs than the other one, has a fairly good, for the times, nvidia card, and also keeps rolling with xkb-data being held back.

The other laptop, an even older HP with intel graphics, has been dist-upgraded every day, and both of them have not had weird removals during dist-upgrades, apt is nice that way, to show you in bright red when things are planned to be uninstalled, and I make sure to  closely examine what's in there, and none of the two had any removals planned in the last days.

But, the slower laptop with intel graphics, which I just managed to boot to alternative shell on 6.17-12, was dist-upgraded once more a little while ago, rebooted, and still no GDM.

Everything points to graphics drivers being the issue.

@Teriarch: Thanks for deeply analyzing the problem and the (viable) solution!
But I am still mad on the maintainer not having introduced an interim solution - like yours - or a final one. This small package - and is it really that important? - obstructs so many things (e.g. a working debootstrap as soon as any X11 components are involved, even as dependencies, only). Offering nothing for now nearly a week is a shame!
[Even you were faster :). A pity that you can not "inject" your solution in the official repository.]

 @terroreek

> [...], or do you all think its better to just sit tight for now?

Yes, that's maybe the best. I falsely assumed that the Debian package manager
is to blame, but it is not. The man page of  dpkg-maintscript-helper in section
"Switching a directory to symlink" clearly reads:

"If a real directory is switched to a symlink, you need to make sure before
unpacking that the directory is removed."

xkb-data version 2.46-1 does not remove directory xkb prior to symlink it.
It's not an easy task, because you must ensure that no other packages
use that same directory beforehand. In case at hand the package

keyboards-rg: /usr/share/X11/xkb/symbols/eo_rg

could share the directory, so the package manager keeps the directory
even if it's empty. Hence the symlink has no effect. The recent version
of package xkb-data is definitely broken since they do not follow the
guidelines of dpkg-maintscript-helper, so we have to wait...

Well that depends. They dropped the user space api support. If some of your applications
still needs shared library /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0, say,
then you are out of luck, unless the native nvidia drivers provide that very same library
(which I doubt).

I'm not completely familiar with this xkb-data problem. But if you install siduction and then set on hold xkb-data
(apt-mark hold xkb-data)
there should be no problem with a dist-upgrade. You won't be able to have all packages upgraded as long as xkb-data isn't fixed. but why is this a problem?

nala upgrade
Ok, your system is fine, but I would have done a dist-upgrade instead.

If I hold back a package because of known problems it creates, I would like to keep back all packages which depend on  said package and I would like all dependencies to be calculated. Which can be accomplished only by dist-upgrade.

But I'm not an expert.

Is only my 2 cents

You can probably delete those files. Or, if you think you need them, temporarily move them out of /usr/share/X11/xkb/, do the upgrade, and put them in /usr/share/xkeyboard-config-2

dpkg -r xkb-data
apt autoremove -y

I am not sure if related but I updated the laptop few days ago and now I have issues with the launch of KDE.
Basically there is the kernel log output stopping on Session 2, I press ctrl+f2 and appears sddm with a strange theme asking me to login.
I insert the password and KDE starts but without systemd for the user, so I have to execute manually systemd --user and restart pipewire (that doesn't detect the bluetooth devices).
In logs I have various errors for missing permission and dbus seems doesn't working, probably because isn't the right session.
I think that everthing happened because I was using xorg and not wayland...
I am getting tons of dump i nthe home folder and inspecting them it is seems that kwin has issues to creating a wayland socket.

I did a dist-upgrade and I don't have any package pending but I ithin that is something is wrong.

I don't think that I removed a package but there is a bug somewhere.
The last update on my laptop it was in october so something in the middle broke something.
Attached the systemd log if someone can help.

I saw that various packages were removed but I didn't say anything that could create that issue.
