Public bug reported:

This issue was found on Ubuntu 22.04 LTS jammy but affects all Ubuntu
releases where fwupd < 1.9.1.

When the package fwupd is installed, there is fwupd.service. According
to journalctl -u fwupd.service, it can't handle releases for the UEFI
dbx "device":

FuEngine             failed to get releases for UEFI dbx: No releases
found: Not compatible with org.freedesktop.fwupd version 1.7.9, requires
>= 1.9.1

UEFI dbx is the UEFI Secure Boot Forbidden Signature Database.

Downloading the CAB from
https://fwupd.org/lvfs/devices/org.linuxfoundation.dbx.x64.firmware and
trying to install it with the following command doesn't work either.

$ fwupdmgr install Downloads/fc3feb015df2710fcfa07583d31b5975ee398357016699cfff067f422ab91e13-DBXUpdate-20230509-x64.cab
Decompressing…           [***************************************]
Not compatible with org.freedesktop.fwupd version 1.7.9, requires >= 1.9.1

So the machine is potentially stuck on an outdated version of UEFI dbx
and vulnerable to CVE-2022-21894.
