problem in first installation step: cannot find archive

I am following the instructions from
https://developer.nvidia.com/cuda-downloads
for ubuntu 14.04 and getting the following problem in the first installation step

root@yitzhak-VirtualBox:~# dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb 
dpkg: error processing archive cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb (--install):
 cannot access archive: No such file or directory
Errors were encountered while processing:
 cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb

You have to download the archive first.

Click the download button immediately above step 1.

After the download is complete, then proceed with step 1.

thanks, that was a lazy miss !
