Hi, After Antonio detect some bad behavior and now it appears Rex Dieter . I started to investigate and tried the rpmfusion tools in a new computer. Conclusion I found that rfpkg started not working correctly in some cases, fas username now have to be defined in ~/.fedora.upn [1] , which is part of kerberos configuration of Fedora tools (is set on Fedora kerberos setup) . I think the best is add rpmfusion-cert sub-package of rpmfusion- packager [2], and instead talking I made the sub-package [3] (some hours of work :( ) . With rpmfusion-cert we can create a new cert with fas credentials, we can verify the cert installed and more important, rfpkg is fixed and read the username from the rpmfusion cert, instead rely on one Fedora configuration ...
