thanks
I have gotton past that stage now and it has download and installed the package.
I re-run the following command and I got the same results
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys FDA5DFFC
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedi r /tmp/tmp.MwVuaHgf2V --no-auto-check-trustdb --trust-model always --keyring /et c/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.u buntu.com --recv-keys FDA5DFFC
gpg: requesting key FDA5DFFC from hkp server keyserver.ubuntu.com
gpg: key D9B78493: “NzbDrone contact@nzbdrone.com” not changed
gpg: Total number processed: 1
gpg: unchanged: 1
and then I was able to run sudo apt-get update
but now I have two questions,
First with the script what do I need to put in
path to mono bin
DAEMON=$(which mono)
if I have mono 3.10 ?
and also what should I see in top when I reboot the raspberry, as I have tried it as default so far, and I am not able to web onto the Sonnar http://ip.address:8989
