Totally baffled by the secret magic things to allow the developer subscription for 8.3beta to accept updates from some repo somewhere. Baffled. I have had various subscriptions for years and years and usually they are enterprise licenses or just developer licenses. Sure they cost money and that is fine. However I fell away from RedHat when a lot of things where changing after version 7.4 and I simply went elsewhere. Trying to look at 8.3beta and the installation was the usual bulky anaconda graphical thing. That went fine. Afterwards I did try a trivial "yum update" and was told a mixture of confusing messages.

yum update

Updating Subscription Management repositories.
Error: There are no enabled repositories in "/etc/yum.repos.d", "/etc/yum/repos.d", "/etc/distro.repos.d".

OKay so some magic is needed. Something something magic.

So then I tried "# subscription-manager list --installed" which shows me that Red Hat Enterprise Linux for x86_64 Beta is in fact installed.

I know that. I installed it.

So then I tried :

subscription-manager attach

That just tells me :

Product Name: Red Hat Enterprise Linux for x86_64 Beta
Status: Not Subscribed

Unable to find available subscriptions for all your installed products.

So that does not help.

Then I tried :

subscription-manager register --name=thishostname

This system is already registered. Use --force to override

What ??

subscription-manager list --available

This gives me a huge list of stuff. Piles and piles. Great. Available? I do see a magic "Pool ID" number thing that looks like uuid stuff. Great. Magic.

Then I try :

subscription-manager register --username dclarke --password mypasswordthing --auto-attach --force

That does something and kicks out mor magic numbers. HOWEVER the first bit of output says that The system with UUID magic-number-from-above has been unregistered.

WHAT ??

All local data removed
Registering to: subscription.rhsm.redhat.com:443/subscription
The system has been registered with ID: MORE-MAGIC-UUID-STUFF
etc etc etc ...

Great ??

Unable to find available subscriptions for all your installed products.

What is the magic ??

Is there a magic sequence of incantations and spells in some special magic order ??

Regardless yum does not work. There is some baffling magic to this.
