barman is on the same server as database

when I launch barman check server

What's wrong here ?

Thanks for you time.

it's in the man pages 

Upgrading from Barman 1.X

Version 2.0 requires that users explicitly configure their archiving strategy. Before, the file based archiver, controlled by archiver, was enabled by default.

When you upgrade your Barman installation to 2.0, make sure you add the following line either globally or for any server that requires it:

archiver = on

Additionally, for a few releases, Barman will transparently set archiver = on with any server that has not explicitly set an archiving strategy and emit a warning.

Besides that, version 2.0 is fully compatible with older ones.
