I recently followed a guide to configure Samba but I couldn't get it configured properly. After realizing that the guide was six years out of date I thought I should start again.

I reinstalled samba by first using these commands:

sudo apt-get purge samba
sudo apt-get install samba

But after reading my configuration file (/etc/samba/smb.conf) I noticed that it was the same file, containing the same edits I had made. I then proceeded to delete the directory and then re-install samba again.

However, the directory is not replaced after re-instillation and now I don't appear to have a configuration file. How do I get it back? Or install Samba correctly?
