Definitely the paper- then let it soak well in before putting on the wall.
If it is a heavy grade paper you might even have to repaste it again before
applying. I have even had some cases where i have also had to put a thin
film of paste on the wall (even though the walls had been properly 'sized'
previously) to get good adhesion. Better to spend a little time preparing
than a lot of time repairing!
