[bug report] Downloading mozilla-openh264-2.4.1-2.fc40.aarch64.rpm aborted the installation

[bxue]

Installing Asahi Linux by "curl https://alx.sh | sh" failed in the step where it was downloading mozilla-openh264-2.4.1-2.fc40.aarch64.rpm. I had set working proxies like:

% env | grep -i proxy
http_proxy=http://somedomain.com:3128
https_proxy=http://somedomain.com:3128

The distribution I chose was "Fedora KDE". I have tried the installation in the different date/time for several times in recent days, and it's 100% reproducible at my side. The installation log was like:
