Stable version (recommended)
You can download the latest version of Samba from https://www.samba.org/.
It is always recommended that you install the latest version of the current stable release. If you require to choose a previous series, always choose the last version out of the Maintainance Mode series or at least from the Security Fixes Only Mode. Older version may not contain all improvements, bug- and security fixes. Also if you require help and ask e. g. on the Samba Mailing List, you typically will be told to try a recent version, to ensure that the problem isn't fixed in the meantime.
Further information about Samba Release Plannings and Supported Release Lifetime, you can find at the Samba Release Planning page.
Warning: Never install a development version in production! It may contain untested features and can cause damages to your installation! Development releases are for testing purposes only!

$ git pull
If you receive the following error
fatal: Unable to create '[...]/.git/index.lock': File exists.
