6.6. Attaching a Red Hat Subscription and Enabling the Certificate System Package Repository

Pool ID: 7aba89677a6a38fc0bba7dac673f7993 Available: 1 ...In case you have a lot of subscriptions, the output of the command can be very long. You can optionally redirect the output to a file:
subscription-manager list --available --all > /root/subscriptions.txt
- Attach the Certificate System subscription to the system using the pool ID from the previous step:
subscription-manager attach --pool=7aba89677a6a38fc0bba7dac673f7993Successfully attached a subscription for: Red Hat Enterprise Linux Developer Suite
