[Samba] upgrading Samba

[ZdenekChladek_cyber]

Hello,
I have Debian 8(x64) and there installed Samba 4.1.17 from package 
manager

based on "upgrading-samba4.txt"
I have made:
1] /etc/init.d/samba stop
2] /home/user/Downloads/samba-4.2.2$ ./configure 
--prefix=/usr/share/samba [successfully]
3] /home/user/Downloads/samba-4.2.2$ make [successfully]
4] /home/user/Downloads/samba-4.2.2# make install [successfully]
5] /home/user/Downloads/samba-4.2.2# samba-tool dbcheck
Checking 268 objects
Checked 268 objects (0 errors)

but when I try:
samba --version
Version 4.1.17-Debian
as You see there is still previous version

thank You for any help how to do it correctly.

Regards Zdenek
