Hi,
I have encountered a problem with the update to resilio-sync x86_64 2.5.2-1 through the package manager on the latest Fedora. I have setup the stuff following this blog post https://www.resilio.com/blog/official-linux-packages-for-sync-now-available
Now there is the update to version 2.5.2-1 showing up, but installation fails, because the package is not signed. I have double checked, the key for the repository is installed. So I think it is a error on your side...
