%preun scriptlet (in your case preremove.sh) is called when the package is being removed. This happens even during upgrade, because old package is being removed and new installed. You can check if it is upgrade or not using the value of $1. It is documented for example here https://fedoraproject.org/wiki/Packaging:Scriptlets

  • if [ $1 -gt 0 ] ; then preremove.sh ..... This will be called when you are upgrading package (removing the old version). When you want to call it when the package is really being removed then you have to if [ $1 = 0 ] ; then
