Up2date will silently exit after clicking "Cancel" during the "Package Retrival" stage. I dont know if it was designed to be that way or if its just a bug, but I think it should display a confirmation dialog in case the user accidentally clicked "Cancel".
Definitely agreed. I end up doing this accidentally once every couple of days. The confirmation box would be good logic, as would fixing the cause of hitting cancel in the first place: at least in my case, it's because the width of the box is variable, which moves the buttons around. Instead of accepting the update, I'll forget to move the mouse over an inch and hit cancel instead. -Chris Kuivenhoven
up2date was replaced by pirut and put (package pirut) as of FC5. Only FC5 and FC6 are currently fully supported; FC3 and FC4 are supported for security fixes only. If this bug occurs in FC3 or FC4 and is a security bug, please change the product to Fedora Extras and the version to match. If you can verify that the bug exists in RHEL as well, please change the product and version appropriately. The codebase for pirut and pup is quite different, but if a similar bug exists in pirut and pup in FC5 or FC6, please change the product to pirut and the version appropriately and update the bug report. We apologize that the bug was not fixed before now. The status will be changed to NEEDINFO, and if the bug is not updated with evidence that it is a security bug or a bug that affects RHEL, it will be closed.
Closing per previous message.
