I am facing the above errors when executing vagrant up. Server two installed successfully but repo and server 1 installation will not complete.

Same issue here, anyone can help?

It looks like the first error requires a Red Hat account to apply the subscription to the RHEL 8 client. The terminal command for a quick registered subscription (using your Red Hat account) is this:

subscription-manager register --username --password --auto-attach

Also, the sshpass repo can only be used after it is enabled using the subscription manager:

subscription-manager repos --enable codeready-builder-for-rhel-8-$(arch)-rpms
dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

I tried using these commands in line 65 of the Vagrantfile and still got the same error messages as you did @codes4humanity :

Does anyone else have any recommendations for troubleshooting this issue?

Try putting this in there instead. I had the same issue but this line let me get past that point
