An eror occur while installing VM2

[sarpan]

Hi
I have  got a problem while trying to install VM 2.0.20 into  Joomla 2.5.9, with gantry framework 4.1.8

I am using my local Apache server in Linux Ubuntu.

Only the message I got after pressing upload & install is:

"There was an error uploading this file to the server"


What would be the problem ? Any tips and suggestions would be highly appreciated  .
Regards
Sarpan
