but I get a loading screen then pop nothing happen again, I tried clicking on the download button multiple times but same problem
can anyone help me identify the problem and how to fix if possible
It’s interesting that you only get firmware updates proposed via GNOME Software. Do you see a reason for that (e.g. you’ve just performed an update, and it’s only the firmware updates that couldn’t be updated for some reason)?
GNOME Software acts as a frontend for the fwupdmgr tool in this case. Does the command fwupdmgr refresh proposes the same updates as the GUI? If so, you could try updating via CLI by running fwupdmgr update.
I agree about updating via the terminal.
The dbx can be updated with the command fwupdmgr and you can use the -h option to see the help screen for commands to use. I would use fwupdmgr get-updates to see the available updates and fwupdmgr update to install all available updates.
The rest can be done from the command line with sudo dnf upgrade --refresh
