I'm trying to install Nimbus on the current ubuntu LTS, which has openssl 1, which seems to have dropped support for SSLv2 due to critical security issues. I cant install nimbus since it seems to require it with cumulus, the installation procedure ends with this error:

Creating Cumulus repository with the following commands:

/home/nimbus/nimbus/ve/bin/cumulus-create-repo-admin Repo

Could not create Cumulus repository.

Can it be easily fixed? We really need to upgrade our infrastructure but we do not want to drop nimbus.
