Comment 1 for bug 1703423

Thanks for taking your time to report this issue and help making Ubuntu better.

The version string 1:2.8+dfsg-3ubuntu2.3~cloud0 seems to indicate it might be coming from a different archive (~cloud0). Could you please post the output from `apt policy qemu-system-x86` to see where it is from? As you mention, the xenial and xenial-updates repos should have only 2.5 releases.
