[Hudlug] another go at upgrading

[MICHAEL WEAVER]

I maty take a backup or just copy the file that contains the reposotries 
that you have helped me get permission to access to in order to get 
Luke's Orca package so if the worse comes to the worse and I have to do 
a complete clean install heaven forbid then I can copy the list of 
addresses we have told Ubuntu to go to to get the Orca package back to 
where it belongs so we don't have to configure them again.
I presume the file I would have to make a copy of is something like 
ect/apt/sources.list which holds the data for the reposotries we set.
