E: Unable to locate package gvfs-smb
EDIT: Solved the Samba installation problem, but my main problem is still open :/
EDIT 2: Finally! Googled the whole web and find a answer. I was missing some packages like gvfs-backends, gvfs-common, gvfs-fuse etc. After i installed then i was finally able to find my Windows PC.
Thanks for the help
