Leapp upgrade from centos 7 to alama 8

Support
1

Hello,
I have been testing the Elevate script for upgrading in a air gaped environment and i have recently started encountering an issue. where it seems that the Elevate might not respect the proxy settings in /etc/leapp/files/leapp_upgrade_repositories.repo

it is worth noting that I have been able to do this upgrade not that long ago and this seems new.

the preupgrade check fails here.

the curl error is seems to be pointing at the Elevate script trying to reach the host directly instead of via a proxy. which I can connect to if I try directly.
curl --proxy “http://x.x.x.x” “https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=stock&content=almalinux”

so I found a blog post that offered a work around. but it does not seem like it should be needed. the work around is making a bash script that monitors the following file and injects the proxy every time the file is changed.
/var/lib/leapp/el8userspace/etc/dnf/dnf.conf
