linux-firmware issue

[Little Girl]

Hey there,

After the issue of the linux-firmware update timing out and failing
for many of us the other day, I was finally able to install the
linux-firmware update last Sunday.

Updates have worked smoothly since then until two nights ago. Now,
whenever I check for updates with the Discover GUI (I'm using
Kubuntu), I get this temporary pop-up as a caution or warning at the
bottom of the window, regardless of whether there are any updates or
not, with XXX representing the hash that it displays.

Failed to update metadata for lvfs: checksum failure: failed to
verify data, expected XXX

Note that this doesn't prevent me from being able to grab any
available updates.

Tge sudo apt update command and the sudo apt full-upgrade command are
run regularly on this machine and don't solve the issue.

The apt policy linux-firmware command shows that I've got the
available candidate installed.

The fwupdmgr refresh command and the fwupdmgr --force refresh command
produce the same cautionary output when run with or without sudo.

The fwupdmgr update command produces this result, with XXX
representing the device ID when run with or without sudo:

Devices with no available firmware updates: 
 • XXX
No updatable devices

Someone in IRC suggested looking at the
/etc/fwupd/remotes.d/lvfs.conf file and doing either or both of these
things:

Remove this line if you have it:
keyring=gpg

Replace gz with zst in this line, if you have it:
MetadataURI=https://cdn.fwupd.org/downloads/firmware.xml.gz

I didn't have the keyring line and I changed the Metadata line.
Despite that change, the output remains the same, even after a reboot.

Someone else on IRC suggested that the cause for the pop-up is
intermittent IME, that some "old  commands" may not work any more,
and that this is a question for the #kubuntu-devel IRC channel. I
tried asking about it in that channel that yesterday and today and
got no response after several hours.

I'm hoping that someone in here can tell me whether this is at my end
or the server's end and whether it requires either my or the server
folks' attention or can be safely ignored.
