[DNG] eudev missing dependency
Hi, udevd calls mtp-probe: udevd[436]: failed to execute '/lib/udev/mtp-probe' 'mtp-probe /sys/devices/pci:00/:00:14.0/usb3/3-4 3 2': No such file or directory mtp-probe is contained in libmtp-runtime, so eudev should have a dependency to libmtp-runtime.

I'm not so sure we should add that dependency, it is not present in udev (232-25+deb9u1). And issuing: dpkg -S /lib/udev/* shows e.g. hdparm: /lib/udev/hdparm ifupdown: /lib/udev/ifupdown-hotplug libinput-bin: /lib/udev/libinput-device-group libinput-bin: /lib/udev/libinput-model-quirks util-linux: /lib/udev/hwclock-set libmtp-runtime: /lib/udev/mtp-probe consolekit: /lib/udev/udev-acl Of these only util-linux is a dependency of udev. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

We *MUST* *NOT* include that dependency, since that file comes from a library that has nothing to do with the functionalities offered by udev/eudev. Any package can install scripts under /lib/udev/, and the package that install them is responsible for their removal/update as well.

When udevd calls mtp-probe in it's default configuration, then it must be assured that mtp-probe is present.

Ok, but then find this package that causes mtp-probe to be called, and fix that package dependencies. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Anything else is a bug. Indeed but udev was designed to run any of the scripts it finds in /lib/udev. If libmtp-runtime installs /lib/udev/mtp-probe, *that* is the package that should make sure mtp-probe can be executed. I've tried to find an mtp-probe but the only thing that turned up was /lib/udev/mtp-probe itself. This makes me believe that the message is actually not saying that mtp-probe cannot be found but that it can not (or no longer) find /sys/devices/pci:00/:00:14.0/usb3/3-4 for some reason. BTW, on my system libmtp-runtime appears to have been pulled in by vlc.

BTW, on my system libmtp-runtime appears to have been pulled in by vlc. Hope this helps, It seems /lib/udev/mtp-probe is from package libmtp-runtime, while /lib/udev/rules.d/69-libmtp.rules, which is the rule using the program, is from package libmtp-common. But their declared dependency is reversed: the former is declared to depend on the latter, and not vice versa. Thus, if you happen to install libmtp-common for some reason other than installing libmtp-runtime, you'll end up with that log complaint.
