Certificate errors when trying to run stored programs in SLC Hub

Nico Chart_21517

When a stored SLC Hub program is executed but does not run due to a certificate error, this may because the administrator did not add the internal hub certificate to the operating system of the worker machine(s) of the Hub. For example, on Red Hat Enterprise Linux node:

Log into the worker node as root and run:

ls -l  /etc/pki/ca-trust/source/anchors

If CA.cert.pem is missing or older than /opt/altair/slchub/var/ca/public/CA.cert.pem then run:

cp /opt/altair/slchub/var/ca/public/CA.cert.pem /etc/pki/ca-trust/source/anchors
update-ca-trust force-enable
update-ca-trust extract
hubctl service stop
hubctl service start
