Discover, which I use for upgrades, reports problems with UEFI. There is an update, which Discover refuses to install. Discover reports this message:

UEFI Secure Boot Forbidden Signature Database
Insecure versions of software from Trend Micro, vmware, CPSD, Eurosoft, and New Horizon Datasys Inc were added to the list of forbidden signatures due to discovered security problems. This updates the dbx to the latest release from Microsoft. Before installing the update, fwupd will check for any affected executables in the ESP and will refuse to update if it finds any boot binaries signed with any of the forbidden signatures. ...
It looks like there is a new version of the UEFI boot system, which can't be installed because of signature issues. Is this correct? Is it anything to worry about? Can anything be done to fix the issue? Is the issue likely to be fixed upstream?
I don't use Discover. I use fwupdmgr directly. I have not seen fwupdmgr refuse to update a component (sans no UEFI). Here's the relevant piece of the script I run daily:
if command -v fwupdmgr >/dev/null 2>&1 ; then if fwupdmgr get-devices 2>&1 | grep -q -c 'UEFI ESRT device' ; then echo "Updating firmware" fwupdmgr refresh --force 1>/dev/null && \ fwupdmgr update 1>/dev/null fi fi
I also noticed the db was updated today.
Very interesting. After running by hand the parts of your script that test whether an update is necessary (It is.), I ran the actual update and got the following output. As you see, I replied "n"; would it be dangerous to try "Y"?
BTW: I've been seeing the error message for about a week.
