ເປັນຫຍັງການອັບເດດລະບົບຂອງທ່ານໃຫ້ທັນສະໄໝຢູ່ສະເໝີຈຶ່ງມີຄວາມສຳຄັນ

ສ່ວນນີ້ຈະອະທິບາຍສັ້ນໆກ່ຽວກັບຄວາມສຳຄັນຂອງການອັບເດດລະບົບຂອງທ່ານເປັນປະຈຳ.

All software contains bugs. Often, these bugs can result in a vulnerability that can expose your system to malicious users. Packages that have not been updated are a common cause of computer intrusions. Install security patches promptly to end discovered vulnerabilities quickly, so attackers cannot exploit them.

The following steps describe how to manually download and install new updates by using GUI.

ການອັບເດດດ້ວຍຕົນເອງໂດຍການໃຊ້ CLI

The following steps describe how to manually download and install new updates by using the DNF package manager.

Fedora recommends applying updates offline: packages are downloaded while the system is running normally, then applied during a reboot. This avoids conflicts caused by updating libraries or services that are actively in use.

ຂັ້ນຕອນການດຳເນີນການ

  1. Download available updates:

    $ sudo dnf offline-upgrade download

    ຢືນຢັນເພື່ອດາວໂຫຼດແພັກເກດທີ່ມີຢູ່.

  2. Reboot to apply the updates:

    $ sudo dnf offline-upgrade reboot

    The system reboots, applies the downloaded updates, then starts normally.

  3. Optionally, use the rpmconf command to merge any configuration file changes introduced by the package updates:

    $ sudo rpmconf -a

    To use the advanced merge option, set the MERGE environment variable to an editor capable of performing that function (e.g., export MERGE="vimdiff"). See the man page for details.

    If you install the rpmconf DNF plugin, rpmconf runs automatically at the end of each upgrade:

    $ sudo dnf install python3-dnf-plugin-rpmconf

The dnf-automatic package provides a systemd timer that can automatically download, install, or alert you about available updates. Whether the timer downloads only, installs, or just notifies the options in the /etc/dnf/automatic.conf configuration file.
