Comment 89 for bug 468589

Please either enable the karmic-proposed repository (see link in Martin's post #88) and then do a system upgrade. Or install one of the packages below which is appropriate for you.

For 32 bit ubuntu:
http://archive.ubuntu.com/ubuntu/pool/main/s/sysvinit/initscripts_2.87dsf-4ubuntu12_i386.deb

For 64 bit ubuntu:
http://archive.ubuntu.com/ubuntu/pool/main/s/sysvinit/initscripts_2.87dsf-4ubuntu12_amd64.deb

Then try to reboot and please report whether it works or not.
