I get the same problem already with upstart 1.3-0ubuntu10 when running a remaster script that unpacks an oneiric live CD, chroots into it, adds universe to the sources and installs cups-pdf. The problem does not occur when running the same remaster script with natty. Neither does it occur when manually starting an oneiric live CD and installing cups-pdf.
Instead of installing cups-pdf, it suffices to do "apt-get install --reinstall cups" to get the same behaviour. root@ubuntu:/# apt-cache policy upstart upstart: Installed: 1.3-0ubuntu10 Candidate: 1.3-0ubuntu11 Version table: 1.3-0ubuntu11 0 500 http://archive.ubuntu.com/ubuntu/ oneiric-updates/main i386 Packages *** 1.3-0ubuntu10 0 500 http://archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages 100 /var/lib/dpkg/status root@ubuntu:/# apt-get install cups-pdf Reading package lists...
