Software:

• FOG Version: 1.5.10.1615 Installer/Updater
• FOS kernel N/A
• OS: Ubuntu 22.04.4 LTS

Additional context
if multiple ip addresses are set on the primary network interface, the extra IP address causes the function
openssl req -new -sha512 -key /opt/fog/snapins/ssl//.srvprivate.key -out /opt/fog/snapins/ssl//fog.csr -config /opt/fog/snapins/ssl//req.cnf
to fail as req.cnf has extra lines in it.

User mitigation:
(temporarily) removing the additional IP address, will allow the script to complete.
