I have 7.7 running. Part of the update went ahead with --skip-broken,
but qt5-webkit (epel) and libreport-rhel-anaconda-bugzilla still caused
problems.
qt5-webkit from epel-testing pulled in others of the family, and I don't
see the libreport-rhel-anaconda-bugzilla package in the repos I use, so
I erased it.
HTH,
