I'm on Ubuntu 12.04 using Unity. To try it out, I installed the xubuntu-desktop package. Ever since I have a orange or red update notification (see attachment) in my Unity indicator panel, telling me about recommended and security updates, respectively.
Q: How can I disable the notifications?
What i expect to happen: There is an option to show these updates when you press the update notification. I disabled it and thought it wouldn't show again after a reboot. In addition, I ran dconf-editor and manually checked if the option to hide updates is enabled.
What happened instead: The update notifications are still there, the only way to get rid of them is to do the updates.
