как установить qemu-kvm в ubuntu?

при установке qemu-kvm я получаю ошибку, как показано ниже:

$sudo apt-get install qemu-kvm 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package qemu-kvm is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  qemu-user:i386 qemu-user

E: Package 'qemu-kvm' has no installation candidate

может кто-нибудь помочь мне, как исправить эту проблему и установить qemu-kvm?
