    Unable to check for firmware update: public key mismatch

    Anybody else seen this?

    Problem:

    1. Run system76-firmware.
    2.Output to the shell is:
    Code:
    2019-04-19 22:29:23,142  ERROR  Failed to download firmware for oryp3
    Traceback (most recent call last):
      File "/usr/lib/python3/dist-packages/system76driver/firmware.py", line 414, in _run_firmware_updater

        message, timeout)
    dbus.exceptions.DBusException: org.freedesktop.DBus.Error.Failed: public key mismatch
    3. App window displays:
    Code:
    Could not download firmware. Please check your network connection and try again
    Steps taken:

    • I've confirmed that system76-firmware is communicating with system76-firmware-daemon via DBUS.
    • I see the "public key mismatch" message coming over DBUS.
    • I've confirmed that system76-firmware-daemon is connecting with firmware.system76.com
    • I Purged and reinstalled the system76-firmware-daemon package.


    System:
    • Oryx Pro, model oryp3
    • Ubuntu 18.04(bionic)
    • Ubuntu packages all up to date.

    I have this same issue with my Galago Pro. I even took the step of zeroing my hard drive and reinstalling the system software from scratch.

    There was an update to the system76-firmware package for all releases, the new version is 1.0.4~1555610581.

    https://launchpad.net/~system76/+archive/ubuntu/pop

    The standard update method will upgrade this:

    sudo apt update
    sudo apt upgrade
