I run testing. I upgraded all my packages a week or so before, then I installed the GUI package. My expectation was that the qemu-system package would be upgraded to match. > At any rate this is definitely not an important issue, with a trivial > resolution too (installing the right version of both components, - which > should be relatively easy to understand from the above error message). It prevents use of the package, you say it's a trivial fix but I only guessed at what to do, and I'm a Debian Developer. Other users may find themselves stuck. >> A versioned dependency would ensure that I had the correct versions of >> things and everything would work together. > > Which package, in your opinion, should depend on which? The -gui package should depend on qemu-system-* relevant for the platform first, or any other qemu-system-* package to avoid installing the one for the platform if another one is already installed. Although maybe that's not right either and apt just isn't built for this scenario. > Please note that qemu-system-x86 already recommends qemu-system-gui > with proper version.

Nope, this is my desktop that I use every day, it's not some weird setup, it's as close to standard Debian defaults as is possible. Thanks, Iain.
