I tried to update clamav with yum (yum update clamav), but I received this message. http://apt.sw.be/fedora/3/en/i386/dag/repodata/primary.xml.gz: [Errno -1] Metadata file does not match checksum Trying other mirror. Error: failure: repodata/primary.xml.gz from dag: [Errno 256] No more mirrors to try. What do I have to do? Can you help me? Thank Andrea
