[Bug 1622958] Re: tasksel --task-packages <task> not working

[Dimitri John Ledkov]

Note that tasksel in xenial is significantly newer than the one in
trusty.

The output generated by taksel, is something that apt understands e.g.:

$ tasksel --list-packages server
server^

One can use --dry-run to check what would apt do, when asked to install
the server task:

$ apt --dry-run install server^
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

Title:
  tasksel --task-packages <task> not working

Status in Ubuntu on IBM z Systems:
  Incomplete
Status in tasksel package in Ubuntu:
  Incomplete

Bug description:
  Kernel: 
  Linux lnx 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:05:09 UTC 2016 s390x s390x s390x GNU/Linux

  Description/Reproduction:
  the command "tasksel --task-packages <task>" is not working

  root at lnx:/etc/apt# tasksel --task-packages server
  server^

  The command does not hang. It is the output.
  The 16.04.01 is the first release for s390x. There was no release before.

  tasksel --list-task works fine

  I can also invoke ncurses menu with tasksel.

  Attached you can find the sosreport.

  I expect to see (ppc Ubuntu 14.04.4 LTS):

  root at srv01:~# tasksel --task-packages server
