Solved: Redhat Satellite Subscription error: Unable to find available subscriptions for all your installed products.
Today we will see how to resolve one of the most common error we used to encounter while migrating a host on satellite server.
Error Message

Solution
1. Delete the host from Satellite GUI
Hosts--> All hosts
2. Check out the /var/lib/dhcp/dhcpd.leases file and delete all entries that belong to this host.
In my case, i found two entries to delete.
host host99.ngelinux.com {
dynamic;
hardware ethernet 00:15:5d:fc:6e:11;
fixed-address 10.56.228.15;
supersede server.filename = "grub2/grubx64.efi";
supersede server.next-server = 0a:04:42:45;
supersede host-name = "host99.ngelinux.com";
}
host host99.ngelinux.com {
dynamic;
deleted;
}
After above steps, when i migrated the host , it was migrated successfully.
