Title: udev /dev/null incorrect permissions after package auto upgrades Status in systemd package in Ubuntu: New Bug description: I've been attempting to determine root cause of this problem for months. Symptom is group/other permissions being dropped from all /dev/* files. This only occurs on some machines, so some machine udev updates work, some machines quietly fail. Looks like the problem relates to... 1) APT /etc/apt/apt.conf.d/10periodic APT::Periodic::Update-Package- Lists == 1, which triggers auto upgrades for critical packages. 2) This triggers the udev package run as an unattended/automatic upgrade. 3) When udev package updates, /var/log/dpkg.log shows no errors. 4) /dev/* files have group/other permissions stripped. 5) LXD containers become unstable, as containers /dev points to machine /dev. Temp fix is change /etc/apt/apt.conf.d/10periodic - APT::Periodic ::Update-Package-Lists == 0 to disable all unattended upgrades. Someone let me know where I can find APT/DPKG logs detailing exactly what post install hook scripts run for udev, so I can look for errors. Or if log verbosity has to be increased for this level of logging, let me know how to increase verbosity, so next time udev updates, I can provide logging detail sufficient to generate a fix for this problem.
