I am using Ubuntu 9.10 and am bothered by the sometimes pretty long update progress. sometimes i wish to abort the update-manager, apt-get or synaptics because i need to go, but i think it might break anything. could you advice me how to do it safely, even if some cleaning up is required afterwards?
EDIT: I was just wondering because certainly there is a way to preserve the pre-update condition, e.g. when installing a new kernel. but my guess is, that the installation is postponed to restart then.
