Systemd: package udev 175-0ubuntu9.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Systemd is installed and running instead of the default upstart. It seems the udev package is still looking for upstart anyways.

Ubuntu packages are built with upstart support (only), we do not support another init system at the moment. The failing "start" command in the maintainer script is generated by dh_installinit, and it is not appropriate at all to hack in these manually. This does not only apply to udev, but to all Ubuntu packages which ship an upstart script.

The best solution for now would be for the systemd packages (whichever you use) to provide a compatibility "start" script which starts a service using systemd. Or just do something like "sudo ln -s /bin/true /sbin/start; sudo ln -s /bin/true /sbin/stop" which will disable startup of services completely.
