I have something similar (tasksel: aptitude failed 100) for some tasks while not the same for the end.
fresh install of ubuntu 8.04 2.6.24-18-generic To reproduce any time on my machine sudo tasksel choose DNS, hit ok, this works, bind is installed sudo tasksel choose audio suite (or video suite or 2D3D suite) hit ok then the window shows "installing packages for 2 seconds then exits and back to the terminal command prompt with tasksel: aptitude failed (100) the tasks in /usr/share/tasksel/ubuntu-tasks.desc looks ok to me (but I am no expert). Both following commands are ok and it would install everything apparently. apt-get -s install ubuntustudio-audio aptitude -s install ubuntustudio-audio Anything to do with the fact that it has to install 2.6.24-18-rt?
