Current Server running on RedHat 8.0

Hi

Maybe someone can help me, I was running current server hapily on Redhat 
7.3, and everything was fine, but I have upgraded this server to RedHat 8.0

now when I try and create the redhat8.0 channel I get this error for all 
the packages ??

Dec 12 08:1005 : EXCEPTION in /usr/share/current/channel.py, 
_getHeaderFromFilename(), 592 [logException()]

Can anyone tell me why the server works fine on RedHat7.3 but not on 
Redhat8.0
