Hello Rohan,

     With that said, how do I go about adding this link to my list of 
repositories?  Before, I would just have to go to the Update Manager, 
and then I would just add the link, now, as a result of not being able 
to launch Update Manager as result of the bad Python3.2 install, I am 
not able to successfully add the link to my list of repositories.  
Again, I thank you for your help.

Best Regards,

Nevins Duret
