That IP "192.168.99.10" doesn't resolve to anything, because I haven't added it to the DNS server. It's also not in /etc/hosts. It's just the IP for the storage network that doesn't use DNS at all.

Meaning the interface ens802f1 has address 192.168.10.194

Why does the setup script think that my hostname resolves to 192.168.99.10?
Please run above python command and see for yourself. Perhaps you have other means it uses for name resolution. Check /etc/nsswitch.conf, getent, mdns, /etc/hosts, etc. Best, -- Didi
