Nag: "The update information is outdated"

[peertje888]

I switched off all updates just because I want to let the system update when I tell her to. But this red triangle in my systray is annoying me terribly a coupe of days after an update which actully forces me to just update it! How can I get rid of the evil red triangle?

sudo apt-get update

make it go away?
