    SUSE Leap update to a new service pack 15.4

    In contrast to Redhat based systems with yum/dnf, SUSE updates are only happening inside the current service pack.
    A zypper update only brings you to the latest updates within a service pack.

    But if you skim the update instructions it boils down to the following commands, which I performed today to bring my server from SP3 to SP4.


    1. Bring your server to the latest patches for your current service pack and reboot:

    zypper update
    reboot

    2. Swich to the new repositories

    zypper --releasever=15.4 refresh

    3. Update to service pack 4

    zypper --releasever=15.4 dup

    4. Final reboot

    reboot

    5. Check Linux version

    cat /etc/os-release


    Of course you should backup and check if you have any special conditions required for applications installed.
    But for a standard server this should be the required steps needed.

    Oh the hole process just takes a couple of minutes and the first reboot was needed, because the kernel changed.
