FTP/sFTP problem

[william drescher]

As of the upgrade to 16.04 LTS I have been unable to use FTP or 
sFTP to put files on the server.  FileZilla works without error 
but trying sFTP manually always get the error 550 Permission 
denied no matter what directory I chose or what the permissions 
are of the directory tree.

I am suspecting it is a error in configuration that does not 
allow uploads.

I checked GOOGLE, but found nothing helpful except a suggestion 
to look at ftp.conf or vsftp.conf, neither of which I could find 
in /etc.

suggestions ?
