Hi, following the oVirt upgrade procedure on a CentOS system (https://www.ovirt.org/release/4.2.0/#centos--rhel) I fail at step `yum update "ovirt-*-setup*"` with a YUM dependency problem: $ yum update "ovirt-*-setup*" [...] ovirt-engine-setup-plugin-ovirt-engine conflicts with ovirt-engine-4.1.3.5-1.el7.centos.noarch [...] $ For the complete yum update output see below. I also noticed, that after having installed ovirt-release42, the old oVirt 4.1 repos were still present on the system. I disabled them manually to no avail. `yum update ovirt-engine` results in "No packages marked for update". Does anyone know, how we can fix this problem?
