What is the meaning of this error?
I added the PSQL for the RHEL 8 repository and am struggling to install the PSQL server because of an unknown error (as root):
cd ~
dnf install postgresql15-server
Output:
Updating Subscription Management repositories.
This system is registered with an entitlement server, but is not receiving updates. You can use subscription-manager to assign subscriptions.

Error:
Problem: package postgresql15-server-15.3-2PGDG.rhel8.x86_64 requires postgresql15(x86-64) = 15.3-2PGDG.rhel8, but none of the providers can be installed
- cannot install the best candidate for the job
- nothing provides lz4 needed by postgresql15-15.3-2PGDG.rhel8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
This means that the license for your RHEL operating system is not correctly registered. Assuming you have a valid license, you can use subscription-manager to activate RHEL with your license, and after that dnf command should work as expected.
