can you give me the full output of the terminal please ?
if it is the error I think it is, type this into terminal :
sudo mv /var/lib/dpkg/info/nvidia-352.postrm /var/lib/dpkg/info/nvidia-352.postrm.bad
then type :
sudo apt-get remove nvidia-352
then all should be well again.
if not, post your full terminal error please.
