I read the man page for udevadm: --reload-rules Signal udevd to reload the rules files. The udev daemon detects changes automatically, this option is usually not needed. Reloading rules does not apply any changes to already existing devices.
However, James' error is quite telling: Jul 31 21:21:46 neptune udevd[409]: specified user 'tss' unknown Jul 31 21:21:46 neptune udevd[409]: specified group 'tss' unknown The package is both adding the user group and a udev rule. It may a bug in udev that it isn't doing another lookup if it can't find the group in its cache, but adding a "udevadm control --reload-rules" seems easy enough and ok for an SRU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959795 Title: package trousers 0.3.7-2ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 137 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/trousers/+bug/959795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
