    The line updates available... in the menu is always there on my install, regardless if updates are there or not.
    It is apparently just an entry in the menu where one can open it and see if updates are there or not.
    Even after I update all, this menu entry remains there.

    So I dont see what to worry abt.

    That string should change to "Software Up To Date" when no updates are available.

    The point is no "online" contacting "home" without permission - or more better (as they say) no online outgoing transmissions or inbound "scanning my system" without permission.

    Makes sense from a security standpoint; if "A" automatically checks for updates by seeing what I have here, then why can't "B" check for TS/SCI headers (or whatever) here and store a cookie, a few random bits, or use my broadband to phone home to ET or UBL?

    Thanks.

    Then turn checking for updates off.

    If you are worried about your OS phoning home to <insert government agency here> use a different OS, lock down your outbound firewall or just don your tinfoil hat.

    If you don't trust the distro you are running, use a different distro. Debian, Mint, Fedora, Scientific, take your pick.

    As a sidenote: Even Debian and Fedora check for updates automatically, if that is a huge deal, turn it off and do it yourself.

    In any case, the packages in the repos are signed with GPG, so their integrity can be verified.

    Is this not a security issue?

    My suggestion would be that if you dislike Ubuntu checking your geo-location, time servers and updates, Ubuntu may not be the distribution for you. Ubuntu is designed to be easy to use for most types of users. If you are removing packages you don't like, possibly breaking your installation, you may be better off using a distribution that allows you much more control of what is installed. This means of course that you will have to learn how to do things the Linux way, instead of doing things the same way you do them in Windows.

    If I want to control what is installed, I usually do a Debian net-install, this allows me to install only what I need, without a lot of extra cruft. I have Debian stable installed on an Apple G4, and I rarely do updates on it, it's been up with the same install for the last 3 years, and I doubt if in that time I've done an update more than 2 or 3 times. I have the system blocked from the internet in my router, and I specifically have to unblock it in order to do any updates. The system serves as an mp3 player, and has no need to access the internet. I turn it on when I go out to my shop, it automagically starts playing music, and when I leave, I turn it off.
