I can't execute the skype file.
I have the permissions I need. What's the meaning of filename* in the ll output?

I suggest you should use the packaged version of Skype. Just enable the Canonical partners repositories in Software Sources (How do I enable the "partner" repository?), click Close, then update the list. After this you will be able to install Skype from Ubuntu Software Center, and it will run properly.
