Getting the following error while upgrading

Transaction check error:

Error Summary
mv: cannot stat ‘_favicon.ico’: No such file or directory

Data directory is not empty!
Solution
Made changes to install.sh where I have removed entry for moving favicon.ico as the file does not exist

exluding libtiff and wget while installing rpm initially and installing it after all rpm's are installed

The above errors shown as part of the upgrade process
