Oh my, I think I can actually help with this one…
If you run: (to fetch the GPG key to verify your package):
gpg --recv --keyserver pgp.mit.edu 0x0EC4FE05
Then export it:
gpg --armor --export 0x0EC4FE05 > bd-pack.key
Then import it to the rpm key ring:
rpm --import bd-pack.key
The key should then be available when you run the file. I think this is just to verify the package hasn’t become corrupted.
You can run all future updates though the application (I went for the GUI as I know naff all about command line at the moment).
