Cannot update Logitech Unifying Receiver (version of org.freedesktop.fwupd incorrect: failed predicate [0.9.2 ge 0.8.1])

There's security update for the Logitech Unifying Receiver (see Screenshot).

Clicking the button does nothing.

I came across this post https://ask.fedoraproject.org/en/question/109038/logitech-unifying-receiver-security-update/ Updating via command line doesn't work either

$ sudo fwupdmgr update

version of org.freedesktop.fwupd incorrect: failed predicate [0.9.2 ge 0.8.1]

The only Google result for the error message is https://blogs.gnome.org/hughsie/2017/05/22/updating-logitech-hardware-on-linux/ . But the comment mentioning it doesn't look resolved.

So how do I install the update? Correct me if I'm wrong, but 0.9.2 is greater than or equal 0.8.1 which means the predicate check is just broken?

    I've opened an issue with fwupd. You need fwudp 0.9.2 or greater to update. Ubuntu 17.04 ships with 0.8.1. One solution is to use a live USB of a distribution such as Xubuntu 17.10 b1 which has a more recent version in its repositories. Since it is a firmware upgrade you can use the other distro to update the Unifying Receiver and then boot back into your normal system.

    • get a bootable USB disk with a distro containing a current version (I went with Xubuntu 17.10 b1, which currently has fwupd 0.9.7). Note that you probably want a 64-bit version of the OS - 32-bit fwupd segfaults if device is plugged in.
    • boot the live distro
    • plug in the receiver
    • apt update
    • apt install fwupd
    • edit /etc/fwupd/remotes.d/lvfs-testing.conf - change Enabled=false to Enabled=true
    • fwupdmgr refresh && fwupdmgr update

  2. I only did a simple search for fwupd from Ubuntu software and installed fw-uefi-tools and then fwupd. This solved the problem (for me on Ubuntu 16.04 LTS).

  3. This worked for me:

    sudo fwupdmgr update; sleep 3; sudo fwupdmgr update;

    I lifted the line from here.

  4. On Ubuntu 18.04 I was able to get past this by following the last two steps of Prinzhorn's answer on my running machine with no extra live CD boot. I did not verify that the edit step is strictly necessary, I just did it and it worked.

    • edit /etc/fwupd/remotes.d/lvfs-testing.conf - change Enabled=false to Enabled=true
    • fwupdmgr refresh && fwupdmgr update
