Something bad happens on RHEL 8 server and it stopped updating. After reading EC2 docs I need to run:
subscription-manager register
But I got an error or message that said:
This system is already registered. Use --force to override
What to do? Shall I pass --force option? Is it safe?
I am not sure how AWS manages. But typically we can list subscription and product information as follows:
subscription-manager list
We run:
subscription-manager refresh
All you have to do is run:
subscription-manager attach --auto
Wait for some time as it takes time. Final confirmation:
1 local certificate has been deleted. Installed Product Current Status: Product Name: Red Hat Enterprise Linux for x86_64 Status: Subscribed
Remove all or specific subscriptions from this system
subscription-manager remove
subscription-manager register
We take help of the following simple command:
subscription-manager --help

This worked. Any idea why it was removed?
It is possible that your subscription with RHEL/RHN was ended. Just my guess.
that make sense. i guess our accounting people renewed it later.
