Comment 5 for bug 1256565

This was more a case of worked other than expected. Since it provided feedback ("OK") I had expected that it would also say about the key's presence. So maybe the script is better silent. I have been using it manually and not in another script and usually have followed up with "apt-key list" to verify that "del" ran as expected. It's not a big deal and happens only a few times per year.

An error message with a non-zero exit status would be more what I would expect from the script if it can't find the key. But it sounds like doing that properly is not trivial.
