The fluent-bit.repo file for the latest installations of Fluent-Bit uses a $releasever variable to determine the correct version of the package to install to your system:
Depending on your Red Hat distribution version, this variable may return a value other than the OS major release version (e.g., RHEL7 Server distributions return "7Server" instead of just "7"). The Fluent-Bit package url uses just the major OS release version, so any other value here will cause a 404.
In order to resolve this issue, you can replace the $releasever variable with your system's OS major release version. For example:
The most secure option is to create the repositories according to the instructions for your specific OS.
