Public bug reported: 1) $ lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04
2) nut-server: 2.7.1-1ubuntu1; udev: 204-5ubuntu20.15 3) On a fresh install of Ubuntu 14.04 (amd64), I installed the nut- server package while the UPS was already connected via USB. After installation, the permissions described by /lib/udev/rules.d/52-nut- usbups.rules should have changed the group of the corresponding /dev/bus/usb/*/* node to 'nut'. 4) The owner/group for the /dev/bus/usb node remained root:root. Manually running 'udevadm trigger --subsystem-match=usb --action=change' changed the group to 'nut'. (From past experience tracking down related udev+nut bugs, unplugging and re-plugging the USB cable would yield similar results.) However, that udevadm command is included in the postinst for nut- server, and it is guarded with a pidof check for 'udevd': # ask udev to check for new udev rules [ -x /etc/init.d/udev ] && pidof udevd > /dev/null \ && udevadm trigger --subsystem-match=usb --action=change This most likely needs to be amended to include the current process name, 'systemd-udevd'. I checked the control files, and unless the udevd process name has changed back, I believe this will affect vivid, wily and xenial as well as trusty. (I will let someone else add those later tags if that turns out to be the case.) ** Affects: nut (Ubuntu) Importance: Undecided Status: New ** Tags: trusty -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to nut in Ubuntu. https://bugs.launchpad.net/bugs/1540008 Title: USB permissions not set at install time (udevd name changed?)
