I updated my packages Ubuntu 11.10 with Update manager, and got: "The package information was just updated" and "There are no updates to install". But I still have the warning from the restart icon, which is highlighted red. Within it "Restart to complete the updates" is also highlighted in red. I tried sudo apt-get upgrade and got message as:

Fetched 9,465 B in 3s (2,870 B/s) Reading package lists... Done

yifang@Tan02:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Is this a bug for that warning?

    Basically it is the information on updates of critical things like kernel so that the new updates are activated after a restart. You need to restart you computer thats it. – sagarchalise Dec 02 '11 at 05:02
  • I think Ivan is implying that nothing was upgraded during his check of system packages, but he still got the warning to restart regardless? – Scaine Dec 02 '11 at 07:15

I agree with sagarchalise. Certain upgrades like kernel updates, driver updates and critical system and security updates need your system to restart after install. You just have to restart your computer.

I you didn't manually upgrade the system, then it might be that you have configured the updates to be automatically installed.

To check that:

  • Open Update Manager
  • Click on Settings button
  • Click on Updates tab
  • Verify the value next to When there are security updates
  • If it's set to Download and install automatically, then you might want to change that to one of the other values.

Do you have the file /var/run/reboot-required? It is set by some packages to notify the system of the need to reboot. If not, it's probably a bug.

Also see How can I tell what package requires a reboot of my system?
