I am currently trying to install KX Platform 4.7.1 on a fresh Ubuntu 20.04 install but I keep getting a checkhost error and looking at the logs I can't find the specific error that is causing problems

&nbsp;

If anyone can offer any advice I have attached the log mentioned.

&nbsp;

# $ ./install.sh

# == install.sh [2.1.7] ==

_Kdb+ licenses (`k4.lic`) are tied to the hostname of a machine and specifically the hostname in FQDN (`<HOSTNAME>.<DOMAINNAME>`) format.&nbsp;_

&nbsp;

The installer expects the hostname to be the the required FQDN format .i.e `server1.company.com`
