F22 to F23

Hi list   I would use the Easter days to upgrade my Fedora 22 system til Fedora 23, but, as you can see, i ran into some problems.    Command used to upgrade: DNF SYSTEM-UPGRADE DOWNLOAD --RELEASEVER=23 Result: /   package clamav-scanner-sysvinit-0.99-2.fc22.noarch requires clamav-scanner = 0.99-2.fc22, but none of the providers can be installed./ /   package clamav-server-sysvinit-0.99-2.fc22.noarch requires clamav-server = 0.99-2.fc22, but none of the providers can be installed./ /   package perl-MythTV-0.27.6-2.fc22.noarch requires perl(:MODULE_COMPAT_5.20.3), but none of the providers can be installed./ /   package perl-XMLTV-0.5.67-2.fc22.noarch requires perl(:MODULE_COMPAT_5.20.3), but none of the providers can be installed./ /   package mythtv-0.27.6-2.fc22.x86_64 requires perl-MythTV = 0.27.6-2.fc22, but none of the providers can be installed./ /   package mythtv-backend-0.27.6-2.fc22.x86_64 requires perl(MythTV), but none of the providers can be installed./ /   package xmltv-0.5.67-2.fc22.noarch requires perl(XMLTV::Date), but none of the providers can be installed./ /   package xmltv-grabbers-0.5.67-2.fc22.noarch requires perl(XMLTV::Date), but none of the providers can be installed./ /   package mythtv-setup-0.27.6-2.fc22.x86_64 requires mythtv-backend = 0.27.6-2.fc22, but none of the providers can be installed/ /   (try to add '--allowerasing' to command line to replace conflicting packages)/   And it is not an option to use '--allowerasing' or to set packages to user installed   regards,   peter med venlig hilsen Peter Meyland Søndermarksvej 15, 1.th. 4200 Slagelse Tlf.: +45 2122 3345
