Error durring the addition of a plugin

Ok, I found the issue...
The command : sudo wget -O /var/www/projeqtor/plugin/translationFrench_V1.2.zip ' www.projeqtor.net/plugins/vmcustom/downl...a.php?uid=7039&pid=2'
return now a wrong zip file. When I try to download the plugin with the navigator, I have the following message 'Permission denied!'.
With the command line, I have no error but i can see that the file size is only of 18o... And it's no possible to unzip it.
How can have a permalink to this free plugin?

$ sudo wget -O /var/www/projeqtor/plugin/translationFrench_V1.2.zip 'www.projeqtor.net/plugins/vmcustom/downl...a.php?uid=7039&pid=2'

I've created a automatised installation script with vagrant.
I just want share with my collaborators a vagrantfile to do a full installation of projeqtor (just to test the tool).
Without permalink, I have to install the plugin manualy each time...

Maybe it will be more easy to propose a vagrant file with database version already initialised and plugin installed....
=> that is the virtual machine and it's too heavy to be shared...

NB : we won't propose permalink as it could open a backdoor to "non free" plugins...
=> ok. I understand... That is not important, I have a workarround... I'll put the zip of the plugin into a synchronized folder (with the vm).
