2.2 Performing the Upgrade ​

bash
dnf update | tee update_log

Note:

  1. If an error is reported during the upgrade, run dnf update --skip-broken -x conflict_pkg1 |tee update_log to avoid the problem. If multiple packages conflict, use the -x conflict_pkg1 -x conflict_pkg2 -x conflict_pkg3 options to skip the packages and analyze, validate, and update the conflicted packages after the upgrade.
  2. Options:
    --allowerasing: Allow erasing of installed packages to resolve dependencies.
    --skip-broken: Resolve dependency problems by skipping packages.
    -x: Used with --skip-broken to specify the packages to be skipped.

2.3 Rebooting the OS ​

bash
reboot
