OK I started the process using the Repository option.

I added deb http://www.duinsoft.nl/pkg debs all using Software Sources 
from the system menu, then tried to import the gpg key:

~$ sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 5CB26B26
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring 
--secret-keyring /etc/apt/secring.gpg --trustdb-name 
/etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring 
/etc/apt/trusted.gpg --keyserver keys.gnupg.net --recv-keys 5CB26B26
gpg: requesting key 5CB26B26 from hkp server keys.gnupg.net
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error

I've tried it a couple of times with the same result.  Does this look 
like a temporary problem that will clear up or something else?

Thanks,  Jim
