Linux, no link with OpenBCI HUB [resolved]

Hello everyone,
I'm a new BCI'er and just setting up my kit (Cyton+Daisy, Ultracortex Mark IV headset). I followed the setup instructions very methodically (working on Linux). I made sure my username was in the dialout group, installed the standalone app and I kept getting an error about not being able to connect to OpenBCIHub. I first got those errors while I was waiting for the equipment to arrive, so I thought it would all go away once everything was plugged in. Sadly not. The standalone application just didn't work for me so I followed the instructions to run it in Processing. I've just set everything up and followed every point in the tutorial and got it running to the exact point where the same message fails again. If I've set everything up in Processing, got the latest OpenBCIHub, put it in the sketch folder and all that, but still can't connect to OpenBCIHub, what could the problem be?

Is there any command I can run that might reveal what the problem is? If I can find a USB-USB-C converter then I will try on my Macbook, but I really did want this working with my Linux laptop (Ubuntu 18.04).

Thanks
Alex

    Please understand that we have already removed the Hub from the next version of the GUI,and that previous versions need to simply:
    - Run Hub
    - Hub needs to be allowed to communicate with network
    - GUI 4.2.0 allows quite some time for the GUI to connect to Hub. PLEASE WAIT and don't just mash buttons.

    On Linux, I think you can try running the app with/without using sudo. Also, you can try to go into the data folder and run the Hub by itself first and maybe accept permissions.

    Hi retiutut :)
    Thanks for your reply. After some playing around I saw what was causing the error and luckily the fix was easy enough:
    sudo apt -y install libgconf2-4
    Now it all connects and I can run my fingers along the pins as the tutorial describes and can see the response in the GUI.

    @algmur Glad to hear that you got it to work! As I just shared in another forum post, GUI v5 will not have these kinds of problems. Happy Hacking!
