Comment 1 for bug 109843

Sorry, its probably just me, but I don't understand the nature of the bug you are reporting.

It looks like you did a dist-upgrade and are concerned by the fact that kdebase (and other core kde packages) are automatically removed? Looks like aptitude removing what it thinks are unused packages....was kubuntu-desktop installed? If not, then this might explain what happened.

After installing kdebase manually as I see you did at the end of the screen capture above, did aptitude try and remove it again if you try an aptitude dist-upgrade (ie, is this apparent removal of kdebase by aptitude repeatable)?

Cheers,
Craig
