Debian jessie prompt on every apt-get upgrade, that a newer kernel was installed and a reboot is needed. How can this warning be disabled, because i want to reboot when it fits and i know that there is a newer kernel available?

And a similiar dialog is shown for "you need to restart these services because libraries were updated", which is re-shown again and again, even when i already decided "i want to restart this three ones and the two other ones should not be restarted" before.

  • It's not offering to perform the reboot, is it? It's just a warning; ignore it.

    If you upgrade a lot of hosts (i.e. via apt-dater) you do not want to acknowledge the warning every time. So your advice is not really helpful.

This is done by the needrestart package.

To disable this you can create a file called /etc/needrestart/conf.d/silence_kernel.conf with the line $nrconf{kernelhints} = 0;

Other available options are listed in /etc/needrestart/needrestart.conf
