[Touch-packages] [Bug 574287] Re: tasksel: forcefully removes packages when tasks overlap

[Peter Ludwig]

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.
 Image name: 
"ubuntu-18.04-4.16.0-v7-desktop-odroid-u2-u3-20190308_shrink.img.xz"

  TEST CASE

  1. 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.

Have you tried to disable the UFW 
sudo ufw disable
to check if the Firewall is interfering? You can enable it again with 
sudo ufw enable 
if the firewall it not the culprit.
