I can't update my Mac software to the latest version - Error occurred (102) Every time I click the update button to update my Mac software, a pop up shows up - An error occurred while loading the update (102).

I don't know what to do; I can't update my software.  I hope you can help me.
Launch Terminal and type the following command if
 you are running macOS Sierra:

 open `getconf DARWIN_USER_CACHE_DIR`/com.apple.appstore


Move all the files and folders out of com.apple.appstore. Then relaunch Mac App Store.

You can delete all the files and folders later if Mac App Store works well. ​
