      Hi John,
      if someone does not give a better answer, I would do a factory reset and reflasch the micro SD card again.

      All configurations will be gone after the firmware update.

        Hi John, I'm sorry you're running into this update issue.

        Thanks for sharing those logs! The error you're experiencing is a known issue when trying to update to 2.5.4. However, there is a workaround you can use.

        SSH into your TinyPilot and run the following commands:

        sudo apt-key adv --keyserver --recv-keys 0E98404D386FA1D9
        sudo apt-key adv --keyserver --recv-keys 6ED0E7B82643E131

        Then run the TinyPilot update on the TinyPilot web interface.

        Alternatively, if you have access to the latest version of TinyPilot Pro (2.6.0), I'd recommend re-flashing your SD card instead. The latest version runs on top of a newer operating system and will continue to receive updates. The version you're currently running on won't receive additional updates beyond 2.5.4 without re-flashing with the new operating system.

        I hope that helps! Please let me know if you have any other questions.

            Thanks, that worked fine. I'll get an SD flash set up but my telescope is about 2000 miles away so it's a to do for later. That's why I wanted to update to 2.5.4 as an interim step. Thanks again.

              Perfect! Thanks for the update - I'm glad you've been able to update.

              Feel free to reach out again in the future if you any any other questions.
