Title:
Ubuntu 22.04: libusb-1.0.25 breaks libinklevel and ink
Status in libusb-1.0 package in Ubuntu:
Fix Released
Bug description:
* Impact
libusb as an incompatibility with previous versions which breaks ink
and maybe some other softwares
* Test case
install ink and
$ ink -p usb
it shouldn't segfault
* Regression potential
libusb is used by fwupd, libfprint, cups, boxes, gvfs and others.
Ensure those services are still working as expected (printing, listing
new usb devices on the desktop, fingerprint login, firmware update,
boxes VM usb hardware detection)
--------------------------------------------
The following packages are installed:
1. libusb-1.0-0/jammy,now 2:1.0.25-1ubuntu1 amd64
2. libinklevel5/jammy,now 0.9.3-3 amd64
3. ink/jammy,now 0.5.3-3 amd64
Command invoked is:
ink -p usb
Result is a segmentation fault. Backtrace in gdb:

I have compiled libusb-1.0.26 into my $HOME and pointed
LD_LIBRARY_PATH to it. Then I get the expected result:
ink -p usb
ink 0.5.3 (c) 2018 Markus Heinz
hp deskjet 5550
Black: 0%
Color: 0%
ldd /usr/bin/ink
linux-vdso.so.1 (0x00007ffe6e47b000)
libinklevel.so.5 => /lib/x86_64-linux-gnu/libinklevel.so.5
(0x00007f479dd44000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f479db1c000)
libusb-1.0.so.0 =>
/home/markus/privat/programmieren/c/printer/libusb-dist/libusb-1.0.26/libusb/.libs/libusb-1.0.so.0
(0x00007f479dafc000)
/lib64/ld-linux-x86-64.so.2 (0x00007f479dd79000)
libudev.so.1 => /lib/x86_64-linux-gnu/libudev.so.1 (0x00007f479dad2000)
So I have the assumption that there is a regression in libusb-1.0.25
which has been fixed in libusb-1.0.26.
On Ubuntu 20.04 there was no problem with libusb and libinklevel /
ink. It just appeared after the update to Ubuntu 22.04 which I did
today.
