Ubuntu – I recieve “Firmware is not ready to run!” & “PKCS#7 signature not signed with a trusted key” when trying to boot


Title explains my question. The image below contains all the errors. I messed around and eventually got apt upgrade and update to go in recovery mode so all my packages should be good now.

I've done some reading and some people say it may be from my Nvidia GPU? If it helps I have a PNY 1060 6gb.

  • I uninstalled Nvidia drivers with apt-get remove --purge nvidia-* and then apt autoremove and it boots as expected now.
