Bug Description

udev update has broken ubuntu's ability to import photos in digikam, gphoto2 can no longer see usb camera, entangle can no longer see camera
after Upgrade: udev:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd-timesyncd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libpam-systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libpam-systemd:i386 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libsystemd0:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libsystemd0:i386 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libnss-systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libudev-dev:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libudev1:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), libudev1:i386 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10), systemd-sysv:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.10) ubuntu no longer allows gphoto2 or entangle control of my dslr, lsusb sees the camera fine, but the upgrade broke the usage, and cant roll back shows it will break system to roll back please fix ASAP.

Ok that shows ACLs are present. But I also just realized this was about still photography, not video, so those aren't the relevant devices. Less straightforward to find the right devices for a USB camera.

Okay, so looking again at the diff from 249.11-0ubuntu3.9 to 249.11-0ubuntu3.10[1], the only udev change is a new symlink for nvme devices. It seems very unlikely that this is related. The only other change that would be suspicious to me is the systemd.postinst change, i.e. requesting a reboot for this upgrade (because of bug 2013543), and not re-execing systemd.

Since no one has indicated otherwise, can you please tell us if this bug persists after (a) sudo systemctl daemon-reexec, and/or (b) reboot?

I have not yet looked into the details of the packages you are trying to use, so I am not sure if the above will help, but it will be very quick to test.

since we don't see the format string arguments, this doesn't tell us what's being printed that's a problem or how it could be systemd-related.

I'm attaching the /lib/udev/rules.d/60-persistent-storage.rules from the previous version of systemd, 249.11-0ubuntu3.9. Since this is the only change in the new version affecting udev, even though we don't see how it would break your devices, we should test whether reverting this fixes your problem.

Please download the attached file and run the following commands:

sudo cp -a /lib/udev/rules.d/60-persistent-storage.rules{,.bak}
sudo mv 60-persistent-storage.rules /lib/udev/rules.d/60-persistent-storage.rules

Then reboot and report whether this has fixed your problem.

If it has not, we can walk you through a full manual rollback of the systemd package on your system.

I cant roll back or lose functionality and software. Im not sure how all this works together, but that update really messed things up, and I am no Programmer or Engineer, but normally I can with a little bit of digging, figure things out, but this has me very confused, as none of this should be tied together, and the bug has to do with how udev handles protocols for camera to software, because the computer can in fact see the camera when attached, the software is simply blocked from seeing the camera. USB harddrive not affected, I tried to reprogram my hand held Ham radio via usb, worked fine, it simply between what ever protocols ubuntu, udev and software packages use to see and communicate with cameras. And as a digital creator, this is a huge issue for me. If I do a fresh install I lose another 2 days getting everything back up running, not to mention I dont have extra drives right now for backing up, nor the funds to buy one, also the reason I have yet to, is if I do, and go to update, and this all happens again, then I am further behind. So I am trying to figure out how this update broke my system, and fix it so it is right.

More interesting info, so I just tested digiKam-8.1.0-x86-64.appimage and it Can talk to my camera, but the Installed digikam package CAN NOT TALK, but I still can not use gphoto2 to stream my camera, nor can I use entangle to use my camera tethered. Because they can not talk to the camera, I understand the appimage has everything self contained, so it makes sense it works that way. But I wanted to let you know, as somehow it may be useful to figuring out this very odd bug.

Please install the attached apt preferences file to /etc/apt/preferences.d/ (as root) and then run 'sudo apt update && sudo apt upgrade'.

This should offer to downgrade all binary packages from the systemd source package to the current jammy-updates versions, without removing any other packages.

After doing so, you can run 'sudo rm /etc/apt/preferences.d/systemd-downgrade /lib/udev/rules.d/60-persistent-storage.rules.bak'.

Then reboot and let us know whether the problem with digikam, gphoto2, et al persists.

A shorter version that avoids the preferences file is:

sudo apt update && sudo apt install --no-remove '?installed?source-package(^systemd$)/jammy-updates'

Unless something else depends on a newer systemd in which case both don't work, but essentially this should.

PROBLEM STILL PERSISTS, and Now I HAVE NO AUDIO. No I have to do a fresh install. You guys really need to pay better attention to your updates, this is a system break not an upgrade. Im really not happy, and as I love ubuntu, and I really appreciate all the hard work you guys all put into making and keeping it great, sometimes I wish you took just a few extra minuets to verify nothing will break with your new updates. It sure would saved all of us a bunch of work. Now back to re-installing ubuntu and putting it all back together, hoping your update does not break it again.

You didn't show the output of the apt command or otherwise confirm, but I
did stipulate that:

If other packages were removed, but you proceeded with the downgrade, then
there could understandably be other regressions.

If no other packages were removed, but systemd was downgraded to the
249.11-0ubuntu3.9 version that you had installed before the most recent
stable release update, and you are having these problems, then there is no
evidence to indicate these problems are caused by either the downgrade, OR
the upgrade of systemd.

No, that doesn't make sense, because the only point at which any of these
applications, either as appimage or deb, should be interacting with anything
handled by systemd, is when opening the device file and either succeeding
or getting permission denied. This is a question of udev acls, which should
apply equally to the appimage and the native .deb, unless the appimage runs
as a different user with different privileges. (And if it runs with
different privileges, whatever is setting up those "different privileges"
could be the actual source of your bug.)

My next step for debugging this problem would be to run 'strace -efile
digikam 2>&1 | grep /dev.*EPERM' to confirm whether there is a permissions
problem on your device files.

Yours is the only bug report of problems with this SRU and it so far has not
been reproducible. If we continue to be unable to reproduce it and you are
not able to assist with further debugging to isolate the problem on your
system, then this bug will eventually be closed and the update will be
re-published to jammy-updates.

This explains the loss of audio after downgrade.

Unfortunately the semantics of package pins do not match on foreign-arch
packages without explicitly listing the arch name.

And for some reason, you had pipewire installed on your system for the wrong
architecture.

Julian's apt commandline approach appears to avoid this problem.

But you appear to have committed the results of either the pin-based
downgrade or a synaptic downgrade, without paying attention to the caveat
that it should not remove any packages.

So 'apt install pipewire' (NOT pipewire:i386) should have fixed the audio
regression.

It's still the case that, if the camera problem was still visible after
downgrading all of the binaries that were part of the systemd source
package, there is nothing that points to the camera behavior change being
the result of the systemd update.

Tried all your steps, they kept breaking my system more and more. Had to re-install ubutnu from liveusb, installed synaptic downgraded udev and locked verison, read markings, reboot, update, upgrade reboot, get my audio and bluetooth up and working again reboot, everything works, its your udev update, dont know how, dont know why, and not sure how my system is the only one effected, but its your udev update. Thanks for your help, hope you figure it out before it causes more issues wide spread. Im out for now on this bug. As fresh install and down grade udev and locking version has everything working again.

To reproduce your problem, can you specify steps to reproduce (with version numbers)? Which Ubuntu image did you use for installation? To which udev version did you downgrade? Which camera do you have and how did you connect it to your computer?

Your original bug report was about an upgrade from 249.11-0ubuntu3.9 (the previous SRU version we've now rolled back to) to 249.11-0ubuntu3.10 (the withdrawn SRU which is currently in jammy-proposed).

> Downgrade: udev:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.7), libudev1:amd64 (249.11-0ubuntu3.9, 249.11-0ubuntu3.7)

This shows that after reinstall, you installed the -0ubuntu3.9 version that you reported you already had installed before encountering this bug; and then downgraded to -0ubuntu3.7, the version in jammy-security.

If you are saying that, after upgrading to -0ubuntu3.9, the problem with camera devices was still reproducible for you, then it is definitively not caused by any of the changes in -0ubuntu3.10.

I will therefore be re-releasing the -0ubuntu3.10 SRU.

We are still more than willing to assist you in determining the cause of the problems you're experiencing, but the evidence is not there that this is caused by the latest SRU.

I downgraded to 249.11-0ubuntu3.9, 249.11-0ubuntu3.7 Because I know for a Fact I had no issues with it, My last install was working with 249.11-0ubuntu3.9, you rolled out the update to 249.11-0ubuntu3.10 and that is when all this started. I simply went back to an older version after a fresh install to be safe, one computer and already lost 2 days on it, could not afford to try out 249.11-0ubuntu3.9 again and hope it all worked, I also know for a fact it Broke on 249.11-0ubuntu3.10. Again I am no programmer or software engineer, so you do what you feel is best for the code, I know what broke, when it broke, but I will never know why it broke. Close this bug out if your comfortable with rolling out 249.11-0ubuntu3.10.

I tried to reproduce the failure on a fresh Ubuntu 22.04 installation and was able to reproduce it (see bug #2036244 for it), but I saw this behavior regardless of the used systemd/udev version. I tried different kernel version, but I failed to pin down a set of packages where it worked reliable.
