Register for Red Hat Developer Subscription for Individuals at:

Red Hat Developer Portal

After registering for Red Hat Developer Subscription, register your system:

$ sudo subscription-manager register \
 --username <your_username> --password <your_password> --auto-attach

Update all packages - kernel, glibc, OpenSSL, systemd, everything - to the latest versions available in the RHEL repos.

$ sudo dnf upgrade

Is reboot required? In this case, it was required:

$ sudo needs-restarting -r
Updating Subscription Management repositories.
Core libraries or services have been updated since boot-up:
  * glibc
  * kernel
  * kernel-core
  * linux-firmware
  * microcode_ctl
  * systemd

Reboot is required to fully utilize these updates.
More information: https://access.redhat.com/solutions/27943

To list the affected systemd services:

$ sudo needs-restarting -s

Restart the system.

$ sudo shutdown -r now

For personal machines, especially laptops, you can run:

$ fwupdmgr get-updates 

$ sudo fwupdmgr update

For servers, as of May 2026, it’s recommended not to enable LVFS (Linux Vendor Firmware Service) and not to use fwupdmgr(1). For enterprise servers, use their own purpose-built, out-of-band firmware management tools that don’t require the host OS at all (aka Remote Server Management):

+--------+----------------------------------------------------+
| Vendor | Tool                                               |
+--------+----------------------------------------------------+
| Lenovo | XClarity Controller (XCC) + XClarity Administrator | [*] 
+--------+----------------------------------------------------+
| HP/HPE | iLO (Integrated Lights-Out)                        | [*]
+--------+----------------------------------------------------+
| Dell   | iDRAC (Integrated Dell Remote Access Controller)   | [*] [**]
+--------+----------------------------------------------------+

These tools operate independently of the OS, and you can flash firmware even when the server won’t boot. In contrast, fwupdmgr(1) runs inside the host OS.
