When running the Spectrum sdiclinux installer, it failed when trying to resolve the hostnames:
Error: We were unable to resolve host xxxx from host yyyy
The machine is configured and has enabled both IPv4 and IPv6 yet only IPv6 was resolving in DNS.
We needed to add the IPv4 address to the local machines etc/hosts as:
IP shortname FQDN
For example:
192.168.1.1 spectrum [email protected]
