On the same host, same user, same shell environment can you curl -OL https://rules.emergingthreats.net/open/suricata-7.0.11/emerging.rules.tar.gz? Typically if that works, Suricata-Update should work as well.
Usually when I see the download failing at 99% there is some proxy, or WAF that thinks the rules are malware and dropping the last packets which can result in what you are seeing.
