[Wine] What's the problem with my wine install?

[jammanuser]

i'm trying to install wine on my recently installed ubuntu 8.10, which i installed using wubi-installer to install it on top of my Vista OS, but it wont work!  :?  the first time i tried it, i did it the first method, i.e. adding the repositories in Software Sources, and then ATTEMPTING to download and save Scott Richie's key to my desktop by clicking on that link on the download page...but it just opened up in a web page, and i couldn't figure out how to download it using that method! 

next i tried the command line instructions, following it all the way up to the "T", and that time i managed to get Scott Richie's key in Software Sources, but when i tried to install Wine afterwards, by clicking the install link on the download page, but i got some kind of error! i thought i might be able to go around it, using the Add/Remove feature in ubuntu, but it still wouldn't work! i even tried synaptic, but still obtained an error, saying it had failed to install!

Does anyone know what could be the problem, or if wine can even install on such a setup, i.e. ubuntu being installed on top of Vista, using wubi-installer?????

Thanks to all honest replies!  :(
