Today I used tasksel to add "lubuntu-desktop" to an "ubuntu-desktop" installation. Already installed and noticed by tasksel was additionally: "SSH-Service" and "Print Server".
The installation of "lubunut-desktop" went fine. I logged in to lubuntu- desktop and now I wanted to remove the "ubuntu-desktop" only ... because it is an odroid and disk space is precoius. I ran tasksel and deselected "ubuntu-Desktop". I was logged in and was able to see how my desktop, start menue, icons ... were removed / uninstalled until in the end a completely naked dektop was left. I was not able to run tasksel again. So I had to reinstall again. :(( Ubuntu 18.04 on odroid u3.

Boot Lucid LiveCD 2. run "sudo tasksel" and select "virtual machine host" 3. run "sudo tasksel" and deselect "virtual machine host" 4. watch how tasksel uninstalls your system OBSERVATIONS What seems to happen is that apt vengefully removes ALL of the items associated with one task, including several base dependencies of other tasks (e.g. ubuntu-desktop) One illustrative example is the openssh-server task: This one includes the packages openssh-server, tcpd and libwrap0. From a normal ubuntu-desktop (e.g. ~liveCD) both tcpd and libwrap0 are already installed, and the task-install pulls in only openssh-server. However when the task is removed, all these three packages (openssh-server, tcpd and libwrap0) are forcefully removed. Since libwrap0 is a core dependency of gnome, a large part of gnome will be removed alongside the removal of the task.
