[Bug 2035406] Re: 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

[Steve Langasek]

The backtrace unfortunately doesn't provide any information that points
to how this could be a systemd problem.  The crashing thread appears to
be:

Thread 12 (Thread 0x7f50a9f2e640 (LWP 282533) "ThreadPoolServi"):

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.
