[System] Microsoft Secure Boot certificate expiry June 2026

[Elliot Alderson]

I've just watched this very helpful video from the excellent Christopher Barnatt:

It explains what the situation is, how to check and how to take action if necessary. I've disabled Secure Boot, but following his instructions I've established that I have the new Microsoft certificates already.

It *shouldn't* be an issue here, and probably on most of your normal desktop-focused distros. Kubuntu, and any KDE setup using Discover for the most part, will run fwudmgr to update the keys/certificates. I have seen this on all of my machines already.



But I am sure some will miss it, or have disabled the fwudmgr option in Discover.
