Hi Marius,

thanks for trying out Yapso. See my comments below:

If you launch octave as the root users, it will be installed globally (in 
[OCTAVE_HOME()
/share/octave/packages] I think).

That's strange, the error seem to be related to the package manager. Can you 
install other octave
packages, like the optim  (http://octave.dbateman.org/optim/index.html) ?

Also does the following command work for you?

octave:1> untar('yapso-0.2.1.tar.gz','test-folder')

As a work-around, you can also specify an absolute path for installing a 
package:

pkg install /home/abarth/Download/yapso-0.2.1.tar.gz

I hope this helps!
Cheers,
Alex
