> Can you elaborate on this issue please, how to fix it and reinstall that package?
I think he meant like that: Boot from a live CD. Open a terminal. If you don't know, use sudo fdisk -l to check out what partitions you have and on which one your system is installed. Create a directory, e.g. sudo mkdir /media/hda1 (name doesn't matter). Mount the partition with your system into the directory with sudo mount /dev/hda1 /media/hda1 (or the appropriate partition for your system) Chroot there with chroot /media/hda1 Reinstall upstart or whatever your system is missing to boot (kernel? ubuntu-minimal?) with sudo apt-get install upstart -- Kernel 2.6.17-7-generic fails to boot, I get the BusyBox instead https://launchpad.net/bugs/59792 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
