Log into the cluster Installer node (frontend) and manually download https://mirror.unicluster.org/unicluster/unicluster-repo-4.1.2-0.noarch.rpm

Then issue the following commands in a root shell:

rpm -Uvh unicluster-repo-4.1.2-0.noarch.rpm
yum -y update unicluster
/opt/tortuga/sbin/unicluster-upgrade

After upgrading you will need to run the "ngedit" utility and re-deploy SGE to any desired nodegroups.
