I am trying to install the 10.10.5 update. It seems impossible. Every time I click "update" in the AppStore and confirm the reboot, a dialog pops up: The available updates have changed. When I click "Show details", nothing happens and the update gets added to the installed updates.

Maybe the download is broken? How can I force the AppStore to re-download the patch? Can I install the update anyway? Where does the AppStore put its downloads?
 
Open the temp folder by typing "open $TMPDIR../C/" in Terminal. Remove the files inside com.apple.appstore folder. You can also try to synchronise your system time (system preferences) which can also lead to update problems.

Try downloading and installing the 10.10.5 combo update: https://support.apple.com/kb/DL1832?locale=en_US.

Beginning to think of ignoring it and wait for the next OS X iteration probably coming in a month?
