How did you put the MediaWiki files into the folder? Did you upload them with the shell or did you use FTP (or SFTP)? With (S)FTP I expect such errors to happen way more frequently than when you are using the shell. With the shell, you basically only run an untar command directly on the server - I am not 100% sure, but I would say: Nothing should go wrong then. :-)
