Hi all! This is my first post in the forum, glad to be here!

I have followed the instructions for Update Notifier, now I am waiting for some updates to see how it works.
If I understood right, update-notifier.py starts at boot time, but does the first apt-get update after 4 hours; or I am wrong and it does the first apt-get update at boot time, and then every 4 hours? If the first is correct, could something be added, so there is an apt-get update 2-3 or 5 minutes after boot time?

I also have a problem after installing pk-update-icon and unattended-upgrades, before I found Update Notifier in this thread. Now I have uninstalled pk-update-icon and unattended-upgrades, but in Synaptic, when I click Settings>Repositories, the repositories window does not pop-up, but a "Repositories Changed" window appears. Now I can only use /etc/apt/sources.list to manage repositories.
Can someone help here, or I should better open another thread?
