Currently building an intrepid install with ubuntu-vm-builder like ‘sudo ubuntu-vm-builder kvm intrepid’ will produce:
Creating /var/run/network Reading package lists... Done Building dependency tree... Done E: Couldn't find package linux-virtual Error umount target
This is because there’s no intrepid meta package for linux-virtual, which is what u-v-b tries to install by default to get a kernel. Instead build with ‘sudo ubuntu-vm-builder kvm intrepid –kernel-flavour server.
It looks like the Ubuntu Kernel Team is rebuilding the linux-meta package for intrepid and hasn’t added a new linux-virtual metapackage yet. There was some discussion about this not being done yet in May.
