I debugged the problem and it turns out that there is a bug in the new install-task code.

The reason is that TryToInstall() was used with BrokenFix=False. But unfortunately this mean in apt-speak that apt will fix any broken package automatically and this means that ones it encounters ubuntu-desktop it will auto-install all dependencies and mark those as auto-installed. Calling TryToInstall() with BrokenFix=True (newspeak!) means it won't autofix it and things work fine.

The fix is trivial (but too late for beta :(

A workaround is to just empty /var/lib/apt/extended_states after the livefs build.
