We have been using Red Hat free developer subscription for years, and everything is so far, so good.

However, the testing virtual machine popped an error saying the OS is missing updates because there is no valid subscription.

So, I used the commands in the below screenshot, trying to refresh the subscription on the virtual machine. All the Red Hat account login credentials are correct, and the portal shows 8 virtual machines registered under the current account, so it is within the limit. However, the command got an error Unable to find available subscriptions for all your installed products. , and the registration was unsuccessful.

The virtual machine's OS is Red Hat 7.9, though. We have this testing virtual machine because our production environment is still on this version.

So, we wonder what the culprit in this subscription issue might be. And we highly appreciate any hints and suggestions.

The screenshot of command history:

[root@hostname logs]# subscription-manager clean

[root@hostname logs]# subscription-manager register --auto-attach

We tried the below two operations, and the issue disappeared. So, we don't know which change was directly effective, but we registered the OS.

  • In the context of "Red Hat Account Portal > Systems", there used to be 8 systems of type "Virtual System", so we removed all of them.
  • During the previous attempts, we left a window open for the graphic user interface of subscription management (command subscription-manager-gui), so we closed the window.

Then, we called the commands subscription-manager clean and subscription-manager register --auto-attach in a terminal and it worked as expected.
