The package (which is "experimental", until we have a real Ubuntu package) has been built on a 11.10 Ubuntu, so I don't expect it to run on something as old as 10.04. You can try opening a terminal, running "tagainijisho" from there and copy/paste the error message here so we know what happens exactly, but this will probably be because of too old Qt libraries or the like.
