Hi Paul,
If I understand well, you are trying NetServer 7 alpha 3.
If yes, please remember that this version is in development and testing mode.
A lot of modules and/or functions are not ready or fully functional (“Temporary unsupported modules: Shared folder, including Samba and HTTP shares (a full refactor is needed”).
From the first announcement (about 12 days ago: NethServer 7 alpha 3 released ), the Dev Team from Nethesis and many of us, works to improve and to test the modules, but we must to wait till when the RC version or the Beta 1 version will be ready.
Till then, a lot of changes can occur every day.
So, PLEASE DO NOT USE OR TRY TO USE THIS VERSION IN PRODUCTION!
THIS VERSION IS ONLY FOR TESTING!
If you need a fully functional version, you can use NS 6.7 full, or even NS 6.8 beta1.
You also need to consider that might not be possible to upgrade from version 6.7 to version 7.2.
