I can't subscribe computers to the ubuntu patch

I have subscribe to the ubuntu patch 2004 site but i can’t select any computer. I have all ready ubuntu computer with the bigfix agent shown in the console. So I don’t have access to the patch fixlets.

Has the Ubuntu site gathered content? In the Site properties, does it show a Site Version, or is it still at version “0” ?

I have install 2 version of ubuntu 1804 and 2004 with a bigfix agent. I haves subscribe to the to site patches for ubuntu 1804 and 2004. But the version of the two sites in the sites properties are stil at version 0.
