1. Update the current Fedora release.

   sudo dnf upgrade --refresh

2. Update the system plugins.

   sudo dnf install dnf-plugin-system-upgrade

3. Download the new Fedora release (e.g. Fedora 37).

   sudo dnf system-upgrade download --releasever=37

   Tip: If dnf upgrade returns the error "The operation would result in removing the following protected packages: kernel-surface", skip the kernel update using:

   sudo dnf upgrade --refresh --exclude="kernel-surface*"
   sudo dnf install dnf-plugin-system-upgrade
   sudo dnf system-upgrade download --releasever=37 --exclude="kernel-surface*"

4. Reboot to upgrade the system.

   sudo dnf system-upgrade reboot

5. Install uming and ukai fonts to display CJK characters.

   sudo dnf install cjkuni-ukai-fonts cjkuni-uming-fonts

6. Modify or create the config file at /et/fonts/local.conf. Use the content from local.conf.

   Tip: To better rendering Japanese characters, install Google Noto fonts.
