Downsides / Criticisms

| Issue | Details | |-------|---------| | Branding & repos | yum output defaults to Oracle repos, but they are reliable. Some find “Unbreakable” marketing gimmicky. | | UEK quirks | Some third‑party kernel modules (VMware, some HBA drivers) may need testing. RHCK works as fallback. | | Community knowledge | Stack Overflow / AskUbuntu have less OL content than CentOS/RHEL. | | Oracle’s reputation | Their licensing/call‑home perception worries some admins, but the OS itself is pure open source – no telemetry forced. | | Lifecycle | Oracle Linux 8.5 lifetime is through 2029 (10 years support). Fine for most. |

Missing Wi-Fi drivers after install

  • Oracle Linux 8.5, like RHEL 8, focuses on server hardware. Many Wi-Fi chipsets require additional drivers. Use a USB-to-Ethernet adapter or install the NetworkManager-wifi package if available.
