[ovirt-users] OVirt hosted engine setup dnf config

Hi all, I'm currently installing OVirt 4.4 on CentOS 8 in an hosted engine setup and it fails during ovirt-hosted-engine-setup. Because of our corporate proxy, some changes to the dnf.conf is needed (namely proxy_auth_method=basic) and the config is working fine when running dnf commands the normal way. Proxy configuration is provided via http_proxy, https_proxy and ftp_proxy env vars. The setup fails during a DNF call with status code 407 (proxy auth required). Is there another way to provide that config or any other way to resolve this? My googling didn't help me yet. On the same machine I had a running OVirt 4.3 on CentOS 7 running as a test and now wanted to upgrade (after a complete wipe). Thanks for your help, Raphael content of /etc/dnf/dnf.conf: [main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=True best=True skip_if_unavailable=False proxy_auth_method=basic timeout=120 minrate=90 Log of ovirt-hosted-engine-setup: [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup During customization use CTRL-D to abort. Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine. The locally running engine will be used to configure a new storage domain and create a VM there. At the end the disk of the local VM will be moved to the shared storage. Are you sure you want to continue?
