**e.meitner** · April 20th, 2019

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):

    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.

Same thing happens to me. I have an Oryx Pro 2018.
