Step 3
After the installation has been successful, we will create a configuration file taking as a starting point the sample configuration file which is offered using the following command:
sudo cp /usr/local/turbolab.it/zzupdate/zzupdate.default.conf /etc/turbolab.it/zzupdate.conf
Step 4
Now, we will go to the following file to define zzupdate preferences:
