I'm new at Kubuntu. when I'm trying to install pspp face with this error:sudo apt-get install pspp and result is:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package pspp is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'pspp' has no installation candidate


    sudo apt update

  • You've not provided your release details; I see it available for releases.. but I don't know yours for starters (nor *architecture* as I note it's not available for all architectures for some releases; but that may not be your issue) – guiverc Dec 31 '21 at 12:05
  • how can i find release details ? – hassan hashemy Dec 31 '21 at 12:08
  • Please [edit] your question and show `sudo apt update` also `grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d/` – nobody Dec 31 '21 at 12:08
  • `lsb_release -a` – Error404 Dec 31 '21 at 12:09
  • Does this answer your question? [What does "Package has no installation candidate" mean?](https://askubuntu.com/questions/14685/what-does-package-package-has-no-installation-candidate-mean) – Error404 Dec 31 '21 at 12:09
  • no.actually .i dont know how to add deb http://de.archive.ubuntu.com/ubuntu groovy main universe to sources.list is that help to install pspp? – hassan hashemy Dec 31 '21 at 12:21
  • @hassanhashemy Don't do that! Try using my answer. – Error404 Dec 31 '21 at 12:22
  • I'd agree with skipping the *groovy* PPA add too, my duplicate link has the reason **why** it's not in *focal* (or 20.04) ... I don't use the package so have no experience with it's availability or trustworthiness of the 3rd party/PPA sources so can't comment there sorry. – guiverc Dec 31 '21 at 12:25
