To check for updates in Fedora 32, open a terminal window and enter the following commands:
$ sudo dnf check-update <enter>
$ sudo dnf update <enter>
This will look for updated rpm files and ensure that the system is patched. Note that “dnf” works similar to “yum” used earlier on Fedora.
Actually the update command is deprecated. You should use dnf upgrade now. See man dnf.
Also there is no need to run check-update as the upgrade command will check for available updates and give the option to install them.
