ASU error when moving files to temporary folder
 

Can someone please help me!!!?
I've been trying to update my OS X for so long. I managed to run the AMD software updater but when I finish downloading the update, it says moving packages to temporary folder and it hangs there after giving me this error:

AppleScript Error

/bin/sh: -c: line 92: syntax error near unexpected token `fi'
/bin/sh: -c: line 92: ` fi' (2)

Someone please help me here. I'm really trying but I'm completely new at this.
