Your problem is caused by mixing Debian and Ubuntu packages and expecting them to work without any problems.
kvm is not the only package that you are having this problem with. If you look at your own output from 'apt-get upgrade' you will see that both the ntp and pulseaudio packages are not installing correctly. You need to replace the sysv-rc Debian package with the Ubuntu one, and then check if there are other Debian packages installed on your Ubuntu machine and replace those. Then you will have an Ubuntu machine that might have a chance of working. -- apt-get/aptitude fails to install KVM via recommended update https://bugs.launchpad.net/bugs/375825 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
