Public bug reported:

I'm running both Ubuntu 15.10 and 14.04. I test the Msktutil package all
both machines, however it only works on the 14.04. On the 15.10 the
version is 0.5.1+git8158aa2b-1, and when I try to get the key tab it
will throw out below error message. I downloaded version 0.5.1-1 and it
runs smoothly on 15.10.

Below information is all I can get.

Thanks
