virt-manager is certainly in the repos. Did you not have Internet? Maybe it cut out during this process? Is it repeatable?

[Leó Kolbeinsson (leok)]

@wxl Walter - yes it is repeatable - received on 2 machines 1 barebon and 1 VM - will retest and report back. (Internet was working - that is how the bug was reported)

[Leó Kolbeinsson (leok)]

@wxl - tested on 3rd machine (barebone) and same failure result if selecting full installation with 3rd party apps -- if installed (normal) no 3rd party apps then all good.

Some interesting observations:
 1. This occurs on Kubuntu and Unity
 2. This does NOT occur on Lubuntu
 3. The apt cache (in /var/lib/apt/lists) that comes with the ISO only includes Packages files associated with the ISO on Kubuntu and Unity
 4. The above makes installing virt-manager impossible without doing an update first in Kubuntu and Unity
 5. The apt cache that comes with the ISO additionally includes Packages files for noble and noble-updates (at least universe) on Lubuntu
 6. The above makes installing virt-manager possible without doing an update first in Lubuntu

The only thing I don't understand: why is the apt cache more robust in Lubuntu?

Maybe this is irrelevant. It seems that without Internet, this isn't even exposed as an option. Given that, we could probably just include an update. This probably makes sense. We include one with the third-party software, so we should include one with virt-manager (and also the option to apply updates).
