Ubuntu software to install

Hello, I installed Linux Ubuntu on an ASUS laptop after removing Windows a few months ago. It works well! Recently, I see a window offering to install a software: "unknown software, UEFI CA firmware"

I have security concerns and I’m hesitant to install it.

What do you think?

Thanks a lot

    Hello,

    These are the BIOS updates,

    The laptop must be plugged in to mains and not interfere with the process; the PC is supposed to reboot.

      Hello,

      More precisely the update of the Secure Boot security certificates, but curious on two counts: it should have happened earlier because the previous ones expired in June 2026, and it originates from Microsoft.

      On the second point, it is said that there would be a vulnerability even for computers that only run Linux.

      A bit of reading.

        Thank you very much Brucine. I loooove W_in, of course(!), but I switched to Ubuntu to get a change of scenery! I still don’t feel reassured about installing this thing. I don’t know if there can be consequences of not doing it... we’ll see!

        The consequences are that, in the absence of up-to-date certificates, there is no longer a secure boot and malicious software is likely to target, if not the BIOS, at least the UEFI boot partition by registering its own entries.

        They are surely more significant under Windows, notably 11 (effects in terms of reinstallation...), I don’t know their scope under Linux; they are, in any case, quite theoretical, one does not see why a private individual who does not go looking for trouble where they browse or download (including attachments not monitored) would be exposed.
